Jaeger-LeCoultre Master Compressor Diving Chronograph

Master Compressor Diving Chronograph is a diver's chronograph by Jaeger-LeCoultre.

This model in the series Master Compressor, presented in spring 2007, has - especially for a chronograph - a huge water resistance up to a depth of 1,000 meters. Here the benefits from the special design of the compression key system developed by Jaeger-LeCoultre are used, where not just the crown, but also the chrono pushers can be sealed perfectly and very practically, namely without long screwing. At this depth already a pressure of 890 kilos weighs on the 3.60 mm thick sapphire crystal - roughly the weight of a small car!

By means of its two barrels the watch features the extraordinary power reserve of 65 hours. The blue white display of the power reserve can be read at a semicircular recess at 6 o'clock.

Like all models from the Master Control series also this one has to pass the strict 1,000 hours test in accordance with the company's internal demands from Jaeger-LeCoultre.
