The general look is certainly vintage-inspired, but similar to a number of those new-vintage layouts for your Reverso, these sector dial versions stand on their own along with the chronograph has a mass appeal that’s difficult to contend with. It’s 39mm wide and rocking JLC’s signature Geographic GMT disadvantage, the Master Geographic displays two time zones (along with AM/PM from the away zone). The second timezone is selected using a town disk at six and the crown in 10. In case you’ve ever used this complication you’ll know it’s a practical and easy-to-manage GMT function that borrows just enough out of a world timer to be greater than your casual GMT.The dial design is more asymmetrical (using the offset am/pm indication), but I believe that is the coolest of the 3 models. The sector dial blends well with the complication, and that I feel the GMT is only the ideal functionality to get a yearlong everyday watch. Another plus with the Geographic complication is the fact that it works both when shifting time zones for travel, or assessing other time zones when connecting with colleagues or friends.Those that understand JLC’s offerings understand that they have a lot of beautifully made watches under $10,000. So, while the price point of these sector dial variations is attractive (especially against the backdrop of SIHH), the real achievement here’s the available sizing and the designs which are both lovely and distinctive among their siblings. While I am certain that some will take umbrage with the lack of lume or the exceptionally vintage-inspired hand choice, the layout works so well when viewed as a whole.

The Jaeger-LeCoultre Geophysic Universal Time is, as its name indicates, a universe timer and to the best of my understanding, it is the only world timer available now that also has a deadbeat seconds hand. For those uncertain of how it functions, a universe timer is a drawback that allows the wearer to tell the time in almost any part of the world with the help of the city disc and the 24-hour disc. The precise mathematics requires a little learning curve and some general understanding, but it’s a rather intuitive system.A deadbeat moments is a bit more uncommon, as far as mechanical complications go. The simplest way to describe it is to imagine the moments hand behaving exactly the same way as it may on a quartz watch — a different tick for each second. Also called a true moments drawback, this was historically (much before the introduction of quartz) prized by watch owners as it helped them tell time just into the second. Given the mechanical sophistication in designing a true seconds motion along with the attendant premium in cost, it is not completely a surprise that the complication is uncommon. In addition to Jaeger-LeCoultre’s Geophysic watches, the ones I can think of immediately are the Habring2 Erwin along with the Gr?nefeld One Hertz.An intriguing factoid (and one that Ariel is fond of replicating) is that the caliber 772 motion at the Geophysic Universal Time has just one part less than the motion in the time-only Geophysic True Second, the caliber 770. That number is 274. I’m not completely certain how Jaeger-LeCoultre was able to bring a universe timer complication but reduce the total number of components by one, however they have.The grade 772 can also be equipped with the brand’s proprietary Gyrolab equilibrium. The Gyrolab balance was made to be more aerodynamic and also to improve rate keeping precision with time. The grade 772 beats at 4Hz and provides 40 hours of power reserve. The motion is visible through the caseback and contains the usual decoration in the kind of Geneva stripes, heat blued screws, beveling, and a decorated gold strand.

The history of the dials is somewhat hazy, and nearly all of the big watchmakers made them at one time or another (maybe not a surprise, since most brands were using the identical dial makers). They arise sometime in the late 1920s or early 1930s and can be traced to two programs — officers watches for the military and scientific watches for laboratory use. It’s unclear which came first, however, the style flourished in the ’30s and ’40s, for both pocket watches and wristwatches, with Patek Philippe, Omega, and IWC producing a number of the most lauded cases. Sometime in the late ’40s or early ’50s the prevalence of sector dials began to wane before almost completely evaporating from catalogs.However, recently, the design has become popular again and watchmakers are producing new takes on the classic style. Whether it’s anything to do with the mania for mid century everything that’s cropped up over the last half-decade or not is another matter for another time, but there’s no doubt that sector dials are hot at the moment. And this watch might be one of the trendiest examples.The Jaeger-LeCoultre Geophysic was initially found in 1958 as a special edition watch and has since become a popular favorite for vintage collectors. In 2014, JLC revived the Geophysic tag for a brand new line of watches. The Geophysic Universal Time in steel has been a part of this lineup, followed by a gold version. Here, we examine the steel model onto a bracelet and it’s actually rather interesting how a simple modification like buying a leather strap for a steel bracelet can significantly change the identity of a watch. I am aware this point appears to be self-evident, but the shift from very dressy to quite casual is primitive here, particularly considering that the timeless universe timer dial.
