Introduction
We congratulate you on the purchase of your Jaeger-LeCoultre watch and thank
you for your confidence.
Representing a new generation of divers' watches, the Master Compressor
Diving watch is distinguished by its ultra-high resistance case. Perfectly suited to
exploring the ocean depths, it ensures optimum readability thanks to oversized
numerals and hour-markers, along with luminous hands. The unidirectional bezel
serves to calculate elapsed diving time using its luminous reference triangle.
We invite you to consult the operating instructions and we wish you great
pleasure with your Jaeger-LeCoultre timepiece.
