Similarly, no new model, but I really like these divers :) )))
In basic functional terms, the Master Compressor Diving Pro Geographic allows the reading of time in two time zones. The first is read off the watch’s central hands, while the second is found on the 24- hour format subdial at nine o’clock. This display is synchronized to the city disc located in an aperture at six o’clock; turning this disc to any of the 24 cities representing our 24 time zones will give you an instant reading of time there in the subdial.
But to focus on the simple second time zone abilities of this timepiece is to overlook its truly remarkable innovation. Strap on the watch and your eyes will naturally be drawn to the lefthand side of the titanic 46.3-mm watch case — home to the most technically advanced, all-mechanical diving device known to man, Jaeger-LeCoultre’s proprietary depth gauge.
This marvel of engineering is composed of 24 elements and represents a relentless 1,500 hours of research and development. It takes two hours to assemble and provides an accurate reading of depth to within one meter from zero to 80 meters below sea level. Look closely at the depth gauge and you’ll find a rectangular opening devoid of sapphire crystal that exposes the alchemic workings, known as the membrane. The membrane is the actual apparatus that translates water pressure into a reading of how deep you’re submerged on the watch dial.
In the process of creating the Master Compressor Diving Pro Geographic, Jaeger-LeCoultre studied all other mechanical depth gauges. It found that the Achilles’ heel of these previous systems was that they depended on water entering the internal mechanism to tell depth, which allowed debris to clog the device. In Jaeger-LeCoultre’s proprietary system, water never enters the internal mechanism.
Instead, the contraction and return of the depth gauge’s membrane as water pressure rises and diminishes is supported by a specially calibrated spring around the rail mechanism that allows consistent and accurate travel for the rail at all times. The correct functioning of the membrane is dependent on the correct calibration of this spring.
The origin of the intricate and brilliant engineering of this device is innately connected to the brand’s famous innovation, the Atmos clock; a clock which requires no winding and derives its energy purely from tiny variations in environmental temperature or pressure. Says Jerome Lambert, “Inside the Atmos is also a membrane that contracts and expands according to environmental temperature.
The only difference is that inside the Atmos is a gas that expands or contracts. The solution we have achieved is a spectacular demonstration of how we’ve used our rich history and the total integration of our manufacture to solve age-old problems with totally new solutions.”
