The new Jaeger-LeCoultre Calibre 912 features two additional functions that globetrotters had hitherto dreamed of in vain: world time, in order to get their bearings instantly amid the maze of time zones and an alarm mechanism endowed with a state-of-the-art gong.
Instead of the traditional gong fixed to the back of the case, a closed and angled circular gong surrounds the movement and is secured to the case middle by two pins. It is struck by the hammer at a precise point near this point of attachment. The geometry has been specifically reviewed so as to optimise the qualities of the sound emitted. Finally, a special secret alloy has been used to produce it. These innovations guarantee a powerful and harmonious tone endowed with consistently identical intensity and characteristics, whether the watch is on or off the wrist.
The 24 time zones can be read off by means of the city disc and rotating 24-hour ring. The watch dial also carries a date window with fast adjustment integrated into the alarm function crown, a first on the Memovox alarm movement. The 36.2mm diameter automatic movement, Calibre 912 is equipped with the latest feats of ongoing research: a variable-inertia balance fitted with adjusting screws on the outer rim; unidirectional winding; as well as an oscillating weight with ball-bearings in ceramics - a high-tech offering the invaluable advantage of requireing no maintenance or lubrication.
The Master Compressor Extremem W-Alarm unites for the very first time all the qualities that are indispensable to adventurers of the extremem, for whom borders are only a distant memory.
