Greetings, and welcome to the world of Jaeger-LeCoultre. Today, I’ll be your guide to the Jaeger-LeCoultre Reverso Tribute Moon caliber 853. Caliber 853 is a manually wound, manufactured movement that can be energized by taking the crown in its first position, flush the case, and turning it in a clockwise direction. Turn it gingerly with your fingers loose on the crown. As resistance builds, that’s the watch’s signal to you, that it’s approaching a fully wound main spring.
Do not turn past the point of stiff resistance, as this is the point at which the watch is fully wound, an additional wounding will damage the movement and overwind the watch. Now, there are a number of ways to set the indications of the time piece, starting with the most fundamental, which is the winding and setting crown. Flush the case winds the watch, pulled out to a stop allows you to set the watch.
You turn the crown counter clockwise to advance the hours and the minutes. Now, once you’ve set the time, there are two case flanks correctors that are used for adjusting the radial date at 6:00, and the moon phase within the radial date. The pusher corrector on the flank at 8:00 is used to adjust the moon phase. The pusher corrector on the flank at 4:00 is used to adjust the date.
Now, it’s important to take note that a corrector tool, a pusher adjuster, is included in the boxed accessories set with this watch, and that can be used to quickly and easily actuate those case side pusher correctors. There are some handling restrictions. Now, you don’t want to set either mechanism during its change over. The safest way to do this, is to simply advance the watch through the date change, through 12:00 midnight, and bring it to 6:00 AM.
The danger zone for the date is 8:30 PM to 3:30 AM. This is the period during which the date is engaged in an automatic jump. If you attempt to use the manual pusher adjust during the change over, you will crash the mechanism. So, it’s best to simply set both of them at the same time, advancing through midnight, and the change over to 6:00 AM, setting the moon phase and the date before advancing to the current time.
Now, it’s also important to note that you can set the moon phase precisely, that is, don’t rely on your eye because with a 29 and a half day life, the moon cycle is extremely incremental, and can be too fine to set precisely with the naked eye. Go on to a Internet chart that shows the days past the full moon. Advance the moon, so that its equal distant between the two flanks of the moon phase display.
Before we set the reverse side of the watch, the independent second time zone, it’s worth nothing that since 2016, the new Reverso models has included a quick release strap and clasp combination. You can see the pull tabs on the case back allowing the strap to be removed quickly and easily using only a thumb nail, and no requirement of tools for intervention.
The double deployant steel clasp likewise, features a pusher that releases the clasp from its attachment to the strap. So, you can withdraw both sides of the strap and the clasp from the watch. And then, withdraw the clasp from the strap.
That’s how you can help to avoid accidental drowning. Now, of course, water resistance is not a static feature of a watch, and as it moves farther away from factory service, and more time passes after a factory assembly, the watch will have a relatively less water resistance as seals age, and lubricants dry. Therefore, the factory recommends minimally, every year, having the watch water tested at an authorized service center, where the watch can be verified as water resistant. Or, flagged as no longer water resistant.
Shock and concussion, however, pose more permanent threats to the condition of your time piece. As shock and concussion can actually stop a watch, if damage is severe enough. Disuse the watch during ATV, mountain bike and snowmobile operation, fire arms, marksmanship, tennis, golf or batting as all of these are damaging concussive activities.
Finally, every fine mechanical time piece requires a full service, Jaeger-LeCoultre recommends approximately every two years. This will involve cosmetic restoration of your watch, restoration of hermeticity and water resistance, as well as, cleaning, oiling and regulation of your watch. Ultimately, this should be performed only at authorized service centers that have the specialized equipment, trained personnel, and original factory replacement parts to protect the value of your watch as an instrument, and as an investment. Moreover, only these agencies can back parts and labor invested with the Jaeger-LeCoultre factory service warranty.
