Greetings and welcome to the world of Jaeger-LeCoultre. Today, I'll be your guide to the proper usage, care, and maintenance of your Jaeger-LeCoultre Reverso Tribute Duo Face in pink gold. Now, it's important to note this is a manually wound timepiece, so take the crown in its first position, flush to the case, and turn it gently in a clockwise direction, to wind the watch. Small seconds at 6:00 will begin to beat when the watch is running. Continue to turn until you feel the crown resist substantially. Resistance will ramp up noticeably as the mainspring approaches its maximum wind and 42 hours of power reserve. Once you feel that resistance, stop winding the watch, as attempting to force the crown past that point will damage the movement.

Now, this is a dual time watch, with two faces, and independent time zones. There are two ways to set the time. The first is the conventional way. Take the crown; pull it out. You'll pull it to a stop, and then set minutes and hours. Now, you'll note, on both sides of the case, always rotate a Reverso case by pushing opposite the crown, and you will see on the opposite dial, the minutes and the hours move in sync, and the day night indicator at 6:00 moves in coordinated motion. Now, to desynchronize the reverse dial and the primary dial, there is a slider adjuster built into the case, that's visible with the case rotated. Simply toggle the slider in one hour increments to set the reverse reference dial to a separate time.

It's important to note that the watch has water resistance of 3ATM, 3ATM being sufficient for splashes and, perhaps, if you're caught out in rain storms, but not for actual swimming or aquatic activity, but more on that in a moment. First, let's talk about the unique strap and clasp system fitted to this Reverso Tribute Duo Face. You can see that there is a pull tab for the spring bar at each lug. This allows you to use nothing more than your thumb, with no resort to tools or jewelers, to remove the strap on both sides. Moreover, the clasp, which is a double folding buckle, incorporates a quick release system underneath. You can see, push here, and indeed, that is where you push to release the clasp from the strap. This is excellent if you wish to change the strap in favor of an alternative from Jaeger-LeCoultre, of which many are available on the website, as well as our website: govbergwatches.com.

Now, there are three primary hazards that you'll face in the usage of your watch: water, magnetism, and shock. We mentioned the water resistance of this Reverso at 3ATM, or 30 meters. Now, that's a static laboratory test depth, and should not be confused with actual aquatic swimming potential or diving potential. No, the watch should not be brought down to 30 meters. It's splash and rain only, at that water resistance rating. However, a natural porous material, such as leather, of which the strap is composed, both alligator and calf, is never water resistant, and therefore, should never be brought into contact with moisture.

Now, water resistance, as stated by the factory, is only valid when the crown is flush to the case and disused, therefore, do not use the crown for winding or setting while the watch is either wet or submerged. You can help avoid accidental drowning of your timepiece by keeping that crown down and disused when your watch is wet. Finally, water resistance, unlike mechanical specifications, is not a static feature of a timepiece. Over time, as seals age and lubricants degrade, water resistance will ebb. Therefore, Jaeger-LeCoultre recommends, on an annual basis, having the watch water tested, to ensure that factory rated hermiticity, seal, and lubricant integrity is still in-tact, and still capable of protecting your watch.

Now, it's important to disuse the watch during concussive activities such as batting practice, tennis, golf, firearms marksmanship, or the riding of snowmobiles, ATVs, or mountain bikes, as all of these can shock the movement sufficiently, to damage its delicate apparatus.

If this is the case, service only with a Jaeger-LeCoultre authorized service center, as these agencies solely have the trained personnel, specialized tools, and original factory replacement parts to protect the value of your watch, as both an instrument and as an investment. Moreover, only these agencies can back all labor and parts invested with an original Jaeger-LeCoultre factory service warranty.
