How to Use an OMEGA Speedmaster: A Complete Guide
Key Points:
The OMEGA Speedmaster combines traditional timekeeping with chronograph functions and a tachymeter scale for measuring elapsed time and average speed.
Manual-winding models such as the current Moonwatch Professional must be wound by hand, while automatic Speedmaster references use a rotor and may be suitable for a watch winder.
Correct use of the crown, pushers and subdials is essential for setting the time, operating the chronograph and reading elapsed minutes and hours accurately.
Barrington Watch Winders offers adjustable TPD and rotation direction settings for compatible automatic OMEGA Speedmaster models.
The OMEGA Speedmaster combines conventional timekeeping with chronograph functions and a tachymeter scale, giving the watch far more capability than its dial may initially suggest. The subdials, pushers and bezel can look complex at first, but the main Omega Speedmaster functions are straightforward once you understand what each control does and how the chronograph is operated.
Learning how to use an OMEGA Speedmaster also means identifying the exact version you own. A Moonwatch Professional with a manual-winding movement is operated differently from an automatic Speedmaster or a model with a date complication. These OMEGA Speedmaster instructions explain the dial, winding, time setting, chronograph, tachymeter, everyday care and when a watch winder may be useful.
OMEGA Speedmaster Functions and Key Features
The main Omega Speedmaster functions combine conventional timekeeping with the ability to measure elapsed time and calculate average speed. On the classic Moonwatch, the hour and minute hands show the time, while the continuously running seconds are displayed on a subdial. The large central seconds hand belongs to the chronograph and normally remains at 12 o'clock when the chronograph is not being used. The tachymeter scale around the bezel works with this hand to calculate rates such as average speed over a known distance.
The key features found on a classic Speedmaster configuration include:
-
Hour and minute hands for conventional timekeeping.
-
A running seconds subdial.
-
A central chronograph seconds hand.
-
Chronograph counters for longer elapsed periods.
-
A tachymeter scale for calculating average speed.
-
Luminous hands and hour markers for improved visibility in low light.
It is important to identify the exact watch before following any Omega Speedmaster manual or operating instructions. The current Moonwatch Professional with calibre 3861 and the modern Speedmaster Calibre 321 are manually wound, while the wider collection also includes automatic models. Speedmaster Reduced, Racing and various other references may use automatic movements, while date complications appear only on certain models. Historical Speedmasters even include quartz versions. The controls, winding procedure and additional functions therefore depend on the reference and calibre.
OMEGA Speedmaster Dial Explained: Subdials, Crown and Pushers
An Omega Speedmaster dial explained through the classic Moonwatch layout is considerably simpler than its appearance might suggest. The three subdials divide normal timekeeping from chronograph timing. On the current Moonwatch Professional, the subdial at 9 o'clock displays the continuously running seconds, the counter at 3 o'clock records up to 30 chronograph minutes, and the counter at 6 o'clock records elapsed hours.
One of the most common sources of confusion concerns the large central hand. This is the Omega Speedmaster chronograph seconds hand, not the watch's ordinary seconds hand. When the chronograph is stopped and reset, the central hand remains at 12 o'clock even though the watch itself continues running normally.
The main controls are equally straightforward:
-
The Omega Speedmaster crown at 3 o'clock is used to wind the movement and set the time.
-
The upper pusher at approximately 2 o'clock starts and stops the chronograph.
-
The lower pusher at approximately 4 o'clock resets the chronograph after timing has stopped.
These descriptions apply to the classic Moonwatch arrangement. Other Speedmaster references may include a date, additional time-zone functions or different subdial layouts, so their controls should be checked against the instructions for the specific calibre.

How to Wind an OMEGA Speedmaster and Set the Time
How to wind an Omega Speedmaster depends first on whether the movement is manual or automatic. The current Moonwatch Professional uses the manually wound calibre 3861. With the crown in its normal position, turn it forwards to wind the mainspring. Continue until the crown reaches a definite stop, then stop applying pressure. OMEGA advises against forcing the crown once this point has been reached.
OMEGA recommends winding the current manual Moonwatch once a day. Calibre 3861 provides approximately 50 hours of power reserve when fully wound, so the watch can continue running for longer than a day, but a regular winding routine helps keep it ready for use.
An automatic Speedmaster works differently. Movement of the wrist causes an internal rotor to rotate and wind the mainspring. If an automatic model has stopped after being left unworn, it can generally be given an initial manual wind before being worn, although the precise procedure should be checked for its calibre.
To set the time on the current Moonwatch Professional, the basic sequence is:
-
Pull the crown out to the time-setting position.
-
Turn the crown forwards or backwards until the hour and minute hands show the required time.
-
Use the stopped seconds display for more precise synchronisation when required.
-
Push the crown fully back into its normal operating position.
The Moonwatch Professional does not have a date display. Other Speedmasters may include a date complication, but how to set the date on an Omega Speedmaster depends on the movement. Some use an additional crown position, while other calibres have different correction systems. Avoid applying the date-setting procedure from one Speedmaster reference to another without checking its manual.
How to Use the OMEGA Speedmaster Chronograph and Stopwatch
Learning how to use the Omega Speedmaster chronograph requires only two pushers. The chronograph operates independently of the normal hour, minute and running seconds display, allowing an event to be timed without changing the time shown by the watch.
Press the upper pusher at approximately 2 o'clock to start timing. The central chronograph seconds hand begins moving around the dial, while the minute and hour counters advance as the measured interval becomes longer. Press the upper pusher again to stop the measurement. If required, pressing it once more resumes timing from the same point.
To reset the chronograph, first make sure it has stopped. Press the lower pusher at approximately 4 o'clock and the central chronograph hand and elapsed-time counters return to their zero positions. On the current Moonwatch, OMEGA specifically warns against forcing the reset pusher while the chronograph is running.
To read the Omega Speedmaster stopwatch, use the displays together. The central hand gives elapsed seconds, while the subdials record minutes and hours. For example, a journey lasting 1 hour, 18 minutes and 25 seconds can be read by combining the hour counter, minute counter and central seconds hand. The same principle works for sporting events, meetings, journeys and other timed activities.
How to Use the OMEGA Speedmaster Tachymeter to Measure Speed and Distance
The tachymeter is one of the Speedmaster's defining functional features. It converts elapsed time into a rate, most commonly average speed, using the chronograph seconds hand and the numbered Omega Speedmaster tachymeter scale around the bezel.
The basic calculation behind the scale is 3,600 divided by the elapsed number of seconds. If one unit of distance takes 30 seconds to cover, for example, 3,600 divided by 30 equals 120. The central chronograph hand will therefore point to approximately 120 on the tachymeter.
To measure average speed with an Omega Speedmaster:
-
Choose two points exactly one mile or one kilometre apart.
-
Start the chronograph as the vehicle passes the first marker.
-
Stop the chronograph as it passes the second marker.
-
Read the number on the tachymeter bezel indicated by the central chronograph hand.
-
Interpret that figure as mph when measuring one mile or km/h when measuring one kilometre.
For example, if a car travels one mile in 30 seconds, the central hand points to 120. The average speed over the measured mile was therefore 120 mph. If the same 30-second interval was measured over one kilometre, the result would instead be 120 km/h. The figure represents average speed across the complete measured distance, not the instantaneous speed at the finishing marker.
Knowing how to use an Omega Speedmaster tachymeter also allows measurements over shorter distances. The indicated rate must then be multiplied by the fraction of a mile or kilometre actually covered. If an athlete completes 200 metres, or 0.2 kilometre, while the tachymeter indicates 225, multiplying 225 by 0.2 gives an average speed of 45 km/h.
How to Use an OMEGA Speedmaster for Motorsport and Everyday Timing
The Speedmaster was created as a practical chronograph and its timing functions remain useful well beyond watch collecting. In motorsport, the chronograph can measure a lap by starting it when a car crosses a chosen point and stopping it when the car returns to the same marker. If the distance is known, the tachymeter can also be used to calculate average speed.
The chronograph does not require the tachymeter for ordinary elapsed-time measurements. This makes the watch useful for many everyday tasks, including:
-
Timing a journey or individual stage of a trip.
-
Recording a workout, run or sporting event.
-
Measuring cooking and preparation times.
-
Keeping track of a meeting or presentation.
-
Timing a parking period or another short interval.
In each case, how to use the Omega Speedmaster stopwatch remains the same: start with the upper pusher, stop with the same pusher, read the elapsed time and use the lower pusher to reset after the chronograph has stopped.
OMEGA Speedmaster Water Resistance, Cleaning and Daily Care
Good daily care helps protect both the appearance and mechanical performance of a Speedmaster. Omega Speedmaster water resistance varies by reference, so the specification for the exact watch should always take priority over general advice. The current Moonwatch Professional, for example, has a stated water-resistance rating of 5 bar, equivalent to 50 metres under test conditions.
A water-resistance figure should not be treated simply as permission to use every watch function at the corresponding depth. OMEGA advises against operating chronograph pushers in water unless the particular watch is specifically designed for such operation. The crown should also be returned fully to its normal operating position after adjustment. Periodic water-resistance testing is particularly important for a watch regularly exposed to moisture.
Routine cleaning is relatively simple. A few sensible habits can help preserve the watch:
-
Wipe the case and bracelet with a soft cloth to remove fingerprints, perspiration and dust.
-
Rinse a suitably water-resistant watch with fresh water after exposure to seawater, following the manufacturer's care instructions.
-
Avoid unnecessary contact between leather straps and water, cosmetics, oils or chemicals.
-
Protect the watch from strong impacts and extreme temperatures.
-
Keep older Speedmasters away from strong magnetic fields unless their movement specifications provide suitable magnetic resistance.
OMEGA gives a general servicing guideline of approximately five to eight years, although the appropriate Omega Speedmaster service interval depends on the model, use and operating conditions. Water resistance may need checking more frequently than the complete movement requires servicing.
Barrington Watch Winders Comment: A watch winder can help keep a compatible automatic Speedmaster running between wears, but it does not replace routine care or servicing. Water resistance, seals and movement condition should still be checked periodically, especially if the watch is regularly exposed to water or worn in demanding conditions.
OMEGA Speedmaster Watch Winder Settings for Automatic Models
An Omega Speedmaster watch winder is useful only for references equipped with automatic movements. A watch winder rotates the watch so that its internal rotor moves, helping maintain the mainspring's state of wind while the watch is not being worn. A manual-winding movement has no winding rotor, so simply rotating the watch cannot wind it.
This distinction is particularly important within the Speedmaster family. The Moonwatch Professional calibre 3861 and Speedmaster Calibre 321 require manual winding and receive no winding benefit from a watch winder. Automatic movements, however, have appeared across Speedmaster Reduced, Racing, Broad Arrow, Date and other references.
For an automatic model, Omega Speedmaster watch winder settings should be selected according to the specific movement rather than the collection name. The two principal settings are Turns Per Day, commonly abbreviated to TPD, and rotation direction. Depending on the calibre, winding may be clockwise, counter-clockwise or bi-directional.
Barrington's TPD Database allows owners to search for the recommended winding programme for individual OMEGA models and references. Barrington watch winders provide adjustable TPD and rotation settings, making it possible to configure the programme for the movement rather than relying on a universal Omega Speedmaster TPD figure.
Barrington Watch Winders Comment: Before placing an automatic OMEGA Speedmaster on a watch winder, check the exact reference and movement rather than relying on a generic setting. The correct combination of Turns Per Day and rotation direction helps ensure the watch receives the winding programme intended for that calibre.
Best Watch Winders for OMEGA Speedmaster Watches
For an automatic OMEGA Speedmaster, a watch winder can keep the movement running between wears and reduce the need to reset the time and other indications after the power reserve has been depleted. Barrington offers watch winders with adjustable Turns Per Day and rotation direction settings, allowing the winding programme to be matched to the requirements of a compatible Speedmaster calibre. The options below range from compact single-watch winders to models designed for larger collections.
Barrington Oxford Single Winder - Black
(The Barrington Oxford Single Winder in Black is a compact option for keeping a compatible automatic OMEGA Speedmaster wound between wears. Its five Turns Per Day settings of 650, 750, 850, 1,000 and 1,950 can be combined with clockwise, counter-clockwise or bi-directional rotation, allowing the programme to be matched to the requirements of the watch movement. The winder uses an ultra-quiet Japanese motor and returns the watch to the 12 o'clock position when resting, while Omni and Micro cushion options accommodate different strap and bracelet sizes. It can run from AC mains or four AA batteries, and Barrington's Jump feature allows several single winders to share one AC power source. At just 12 cm wide, 12.5 cm high and 19 cm deep, it is particularly suitable for an owner who wants a dedicated winder for one automatic Speedmaster without taking up significant display space).
2 Watch Winder
(The Barrington 2 Watch Winder is a practical choice for owners of two automatic OMEGA Speedmasters or a mixed automatic watch collection, with two individually programmable rotors that can each be set to one of five Turns Per Day programmes and clockwise, counter-clockwise or bi-directional rotation. Premium Japanese Mabuchi motors and a 12-hour On/12-hour Off cycle help keep operation quiet enough for bedrooms, while each rotor returns the watch to the 12 o'clock position when resting. The cabinet also adds a fingerprint lock with storage for up to 20 fingerprints, a built-in storage drawer and full-function remote control, combining secure presentation with convenient day-to-day use. Because each rotor can be programmed separately, two automatic watches with different winding requirements can be kept in the same unit without using identical settings).
Barrington Oxford Single Winder - White
(The Barrington Oxford Single Winder in White combines the same flexible winding controls as the Black version with a clean, understated finish suited to lighter interiors and display spaces. For a compatible automatic OMEGA Speedmaster, users can select 650, 750, 850, 1,000 or 1,950 Turns Per Day and choose clockwise, counter-clockwise or bi-directional rotation to match the movement's requirements. The ultra-quiet Japanese motor and compact 12 cm by 12.5 cm by 19 cm dimensions make it easy to position on a bedside table, shelf or desk, while the watch returns to the 12 o'clock position whenever the rotor rests. Power is available through AC mains or four AA batteries, and the Barrington Jump feature allows several single winders to operate from one AC power source when a collection expands).
When choosing between these Barrington watch winders, consider not only capacity and design but also how your Speedmaster fits into your wider collection. A single winder may be sufficient for one regularly rotated automatic watch, while a multi-watch model provides dedicated winding positions for several timepieces. Remember that these products are intended to wind automatic Speedmaster models. Manual-winding references, including the current Moonwatch Professional, must still be wound by hand.
OMEGA Speedmaster Instructions: Common Mistakes to Avoid
The most important OMEGA Speedmaster instructions are often about what not to do. Because the collection contains many different movements and complications, assumptions based on another Speedmaster can lead to incorrect operation.
Common mistakes include:
-
Assuming that every Speedmaster uses the same movement, crown positions and controls.
-
Mistaking the central chronograph seconds hand for the watch's continuously running seconds hand.
-
Pressing or forcing the reset pusher while a conventional Moonwatch chronograph is running.
-
Continuing to force the crown after a manual-winding movement has reached its winding stop.
-
Operating standard chronograph pushers underwater.
-
Adjusting a date complication without checking the instructions for the specific calibre.
-
Using arbitrary TPD or rotation settings for an automatic Speedmaster.
-
Expecting a watch winder to wind a manual Moonwatch.
Identifying the exact reference and movement before operating unfamiliar Omega Speedmaster functions prevents most of these errors.
OMEGA Speedmaster Moonwatch History and Why Its Functions Matter
The Omega Speedmaster was introduced in 1957 with a strong connection to precise timing and motor racing. Its chronograph and external tachymeter were practical instruments before the model became associated with space exploration. After passing NASA testing, the Speedmaster was qualified for crewed space missions and subsequently became the first watch worn on the Moon during Apollo 11 in 1969.
The chronograph also played a practical role during Apollo 13. Astronaut Jack Swigert used his Speedmaster to time a critical 14-second engine burn as the crew worked to correct the spacecraft's trajectory. The episode demonstrates why the Omega Speedmaster chronograph is more than a visual link to the model's past. The same basic elapsed-time function remains available to owners today.

Knowing how to use an OMEGA Speedmaster ultimately starts with knowing which Speedmaster you own. Manual Moonwatches need regular hand winding, while automatic references can be kept wound between wears with a suitably configured watch winder. For automatic models, Barrington's TPD Database can be used to identify an appropriate winding programme before configuring the winder.
Conclusion
Learning how to use an OMEGA Speedmaster properly starts with understanding the exact reference and movement inside the watch. The basic principles of winding, setting the time, operating the chronograph and reading the tachymeter are straightforward once the controls are familiar, but details can differ between the manually wound Moonwatch Professional and the many automatic, date-equipped and other Speedmaster variants. Following the instructions for the correct calibre is the best way to use each function as intended and care for the watch over the long term.
For owners of automatic Speedmaster models, Barrington Watch Winders offers adjustable watch winders designed to keep automatic watches wound while they are not being worn. Their configurable Turns Per Day and rotation direction settings allow the winding programme to be matched to the movement, while Barrington's Watch Compatibility database helps identify suitable settings for individual models. Manual-winding Speedmasters, including the current Moonwatch Professional, should continue to be wound by hand rather than relying on a watch winder.
