Master Compressor Diving Chronograph

Jaeger-LeCoultre: Master Compressor Diving Chronograph/2007

Measuring 44 mm in diameter, the Master Compressor Diving Chronograph is water resistant to 1,000 metres - an exceptional feat for a chronograph watch, as well as pushpieces fitted with the compression system.

The hours and minutes, as well as the Chronograph seconds, are shown by central hands moving over the main dial, whereas the chronograph hours and minutes appear in subdials at 3 and 9 o'clock. The date is displayed through an aperture between 4 and 5 o'clock, while the luminescent movement operating indicator is shown in a semi-circular opening at 6 o'clock. The outer dial ring features a pulsometer enabling one to determine the number of heartbeats per minute. This is done by starting the chronograph seconds hand and stopping it after the 30th heartbeat measured. This function is particularly appreciated by sports enthusiasts wishing to optimise their training by taking account of their maximum pulse rates. It proves indispensable for free-diving, precisely because the diver's task consists in reducing their heart rate. Endowed with a comfortable 65-hour power reserve, the Master Compressor Diving Chronograph is available in satin-brushed pink gold, or in a limited edition of 1,500 in satin-brushed grade 5 titanium.
