The Master Compressor Extreme World Chronograph houses the first automatic chronograph calibre ever created by Jaeger-LeCoultre in a titanium case with a revolutionary system of shock absorption. The new automatic chronograph movement (751 and 752 respectively) features 28,800 vibrations per hour driven by a column wheel escapement, and a working reserve of 72 hours thanks to its double barrel.
The long-term reliability is reinforced by the winding bearing, whose ball-bearings are made of ceramic and thus require no lubrication. Offering additional protection against shocks, the inertia of the large balance is regulated by four adjustable screws on the felloe of the balance and the spiral laser is soldered.
In addition to showing the hours and minutes, this powerfully designed watch with contrasting lines of colour displays chronographic functions, a power reserve indicator, and a large date as well as the world’s time zones thanks to a disk connected to a two-armed hand that makes one rotation every 24 hours.
The red, white and black Master Compressor Chronograph provides not only chronographic functions, but also has a very readable tachymeter.
