Omega Speedmaster Moonwatch Chronograph Moonphase 304.63.44.52.02.001 Functions & Care Guide

Tim from Govberg Jewelers explains how to use and care for the Omega Speedmaster Moonwatch Moon Phase chronograph: winding, setting time, moon phase and date, chronograph use, water resistance and sho

Key Takeaways

  • Correct setting and chronograph sequence (stop before reset) prevent movement damage.
  • Avoid quick-setting the date and moon phase between 8 p.m. and 4 a.m.
  • Leather straps must be removed before water exposure, and controls should not be used when the watch is wet.
  • Annual water-resistance testing and periodic service keep the watch reliable.

What the video covers

  • The watch is automatic but can be manually wound; the audible click of the bridal mainspring signals full winding, preventing overwinding.
  • Time is set by synchronizing to an atomic clock reference by pulling the crown to stop seconds and pushing it back in at the correct second.
  • Quick-set functions adjust the date (counterclockwise, one-day steps) and moon phase (clockwise), set by starting from a new moon and advancing by the moon's age.
  • Quick-set adjustments should not be made between about 8 p.m. and 4 a.m., when the automatic date and moon phase turnover occurs, as this can damage the watch.
  • The chronograph must be stopped before it is reset; resetting a running chronograph can damage the movement.
  • The tachymeter bezel calculates speed from elapsed time over a known distance, with an example of a jet car covering a kilometre in about seven seconds (about 500 km/h).
  • The watch is water resistant to 100 meters, but leather straps are never water resistant and should be swapped for textile or rubber before water exposure.
  • Crown and pushers should not be operated while the watch is wet or submerged, to avoid letting water past the case seals.
  • Water resistance degrades over time, so an annual dry water test at an authorized service center is recommended.
  • The watch should be protected from hard impacts and sharp surfaces, and activities like batting, golf, ATV or mountain biking should be avoided; a comprehensive mechanical overhaul is advised every four to five years.

Questions about this video

When should I avoid adjusting the date and moon phase on this Omega Speedmaster?

The presenter advises against using the quick-set functions between approximately 8 p.m. and 4 a.m., when the watch performs its automatic turnover of the moon phase and date. Attempting to adjust during this window can damage the watch.

Can I wear the Speedmaster while swimming?

The watch is water resistant to 100 meters, which is sufficient for swimming, but the leather strap is not water resistant and should be replaced with a textile or rubber strap first. Crown and pushers should not be used while the watch is wet.

How do I know when the watch is fully wound?

When winding manually, you can listen for an audible click or tick from the bridal-style mainspring, which signals that the watch is fully wound. The slipping mechanism prevents accidental overwinding.

Speaker A
[Music] hi I'm Tim welcome to our Channel and thanks for logging on today we're discussing the proper usage and care of your Omega Speedmaster moon watch coaxial master chronometer moon phase chronograph this is an automatic winding timepiece nevertheless you can manually
00:18
Speaker A
wind it take the crown in its first position clutch the case and turn it 30 to 40 turns to start the watch now the watch can automatically wind itself at this point you can set the moon phase the date operate the Chronos at the time
00:30
Speaker A
and the watch will continue to wind itself via the kinetic energy of your wrist but if you wish to fully wind the watch up to its maximum rated power reserve of 60 hours simply continue turning to fully energize the watch will
00:42
Speaker A
require 80 to 100 turns but you can listen for the audible click or tick of the bridal style mainspring the watch automatically slips that bridal mainspring to relieve excess strain or tension so you can't accidentally over wind the watch listen for that click or
00:56
Speaker A
tick as your audible sign that the watch is fully wound the timepiece does feature some subsidiary setting modes that allow you to set the moon phase the date as well as the time of day let's start with the most basic which is the
01:10
Speaker A
setting of the time itself find an online reference such as an atomic clock set your time zone that you know to be accurate follow the constant seconds at 9:00 o'clock because that is your seconds for the time at center and then
01:22
Speaker A
pull the crown out two steps this is what's known as stop seconds 31 because it's a coaxial indicator of the date as well as constant seconds is our 60 or 0 now what I want to do is I want to set
01:33
Speaker A
the time to the correct and current hour but I want to set to the next nearest minute so let's say I want to clear the mono counter at 3 o'clock I'm gonna set my watch it's currently 709 I'm going to
01:48
Speaker A
set my watch to 7:10 so the reference timer is at most 60 seconds behind me I'm gonna wait until that reference catches up so that the same minute hour and second is displayed on the atomic clock and the seconds this
02:00
Speaker A
watch and the display time coincide push that crown all the way back in now you've synchronized to a reference time you also know that the chronograph will stop during that precise setting of the time the timepiece features two quick set functions so if I pull the
02:16
Speaker A
crown to an intermediate position between flush winding and all the way out stop seconds I have the ability to quick set two functions one is the moon phase and one is the radial date so you'll know when I turn the crown in a
02:29
Speaker A
counter clockwise direction I step the date in one day increments and when I turn it in the opposite direction clockwise I step the moon phase let's talk about setting a moon phase in general what you want to do is look up
02:44
Speaker A
the current age of the moon then set the watch to a new moon so get rid of the moon set it to a new moon and then add the age of the moon so if the age of the
02:58
Speaker A
Moon is 11 days from the new moon you're going to turn 11 individual increments and you can see how there are steps increments so you start with the new moon and then you turn the correct number of days corresponding to the age
03:10
Speaker A
of the moon all right so those are the fine setting functions of the moon phase and the day patrols going on keep in mind you don't want to use them 24 hours a day there is a period from
03:21
Speaker A
approximately 8 p.m. to 4 a.m. when the watch is engaged in the automatic turnover of its moon phase and date you don't want to use those quick sets during that period that's the automatic turnover attempting to choose the quick
03:34
Speaker A
set during that period can damage the watch so always take care not to use the quick set for the moon and the date between 8 p.m. and 4 a.m.
03:41
Speaker A
always push the crown back in when you're done using it to preserve the water resistance of the watch as well as to avoid shearing or impact damage now the timepiece does feature a chronograph that has a try register so seconds at
03:53
Speaker A
center and a mono counter at 3 o'clock with co-axial hours and minutes I'm gonna reset it let's talk about using the chronograph there is a sequence to be followed you start and you stop and then you were set you only reset a
04:07
Speaker A
stopped chronograph so always stop before you reset attempting to reset a running chronograph can damage the movement significantly you'll note there's a tachometer bezel the tachometer is used to get to the speed of an object generally a very fast
04:20
Speaker A
object as it's calibrated from 560 units let's say you are looking at a very fast race there are three factors there's time there's the tachymeter calibration there's the distance and that will yield an additional factor which is the speed
04:35
Speaker A
so let's start the chronograph as the race car begins a standing kilometre and when the race car completes that standing kilometre I am going to stop the chronograph now let's say that very fast race car maybe a thrust SSC jet car
04:52
Speaker A
crosses the kilometer and you can see it did so in approximately seven seconds well adjacent to seven seconds is five hundred five hundred kilometers per hour is the speed of that car we set now let's talk about the care of your watch
05:07
Speaker A
a couple of handling restrictions you're going to want to keep in mind water although this watch is water resistant to 100 meters which is sufficient for swimming leather as featured on the strap is a natural porous material that
05:19
Speaker A
is never water resistant so always ensure that the watch is on of water resistant bands such as textile or rubber before immersion or water exposure it's also important to remember that you can help avoid accidental drowning do not wind pull or replace the
05:34
Speaker A
crown do not use the chronograph pushers while the watch is submerged but also while there is water on the case so if the watch is wet diss use all functions until the watch is dry as attempting to use these controls can bypass the case
05:48
Speaker A
seals and introduce water to the interior with catastrophic consequences we wish to avoid that so always remember you can help avoid accidental drowning by just using these controls while your watch is wet it's important to remember the water resistance is not a static
06:02
Speaker A
feature of your watch unlike mechanical specification it does AB with time and change as seals age and lubricants degrade therefore Omega advises on a yearly basis taking the watch to an authorized service center for a dry water test to ensure that the factory
06:17
Speaker A
rated hermiticity is maintained it's also important to note that this is a good time to have the total condition of your watch cosmetic chronometric precision as well as water-resistant hermeticity checked by your authorized service center just in case a full
06:31
Speaker A
service might be needed it's also important to remember that the timepiece should be shielded from high impacting concussion magnetism is no longer the threat it was thanks to omegas si 14 silicon hair spring technology the watch is effectively a magnetic shock however
06:48
Speaker A
remains an age-old hazard to a fine mechanical watch and though this timepiece does meet the Swiss and ISO standards for a internationally acknowledged shock resistant watch nevertheless there are some extremes that should be avoided such as concussive sports batting tennis golf
07:04
Speaker A
firearms marksmanship or the riding of ATVs and mountain bikes dis use the watch during these activities also protect the crystal as well as the sera gold ceramic bezel from hard sharp blows although both surfaces are extremely scratch resistant and will continue to
07:23
Speaker A
look new indefinitely under most circumstances hard blows against unyielding surfaces can crack or fracture these hard materials so always ensure that the watch is kept a safe distance from hard and sharp surfaces that might create a shadow risk for the
07:40
Speaker A
sapphire and ceramic surfaces of your watch ultimately every four to five years pearl Mecca a fine mechanical timepiece will need a comprehensive mechanical overhaul have you watched checked at an authorized service center every year during your water tests because some
