Jaeger-LeCoultre Master Compressor Diving GMT
This model of the series Master Compressor, presented in spring 2007, has the enormous water resistance up to a depth of 1,000 meters. Here the special design of the compression key system developed by Jaeger-LeCoultre shows its benefit, because the crown can be sealed perfectly and without long screwing. At this depth on the 3.60 mm thick sapphire crystal already weighs a pressure of 890 kilos - roughly the weight of a small car!
The blue/white display of the power reserve can be read at a semicircular recess at 6 o'clock. The watch is equipped with a second timezone in 24 hours mode.
Like all models from the Master Control series also this watch has to pass the strict 1000 hours test in accordance with the company's internal demands.
The watch is delivered in two sizes: Over-sized with 46.3 mm diameter and normal size of 44 mm diameter.
