**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 [[barrel]]s 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]].
