Additional information about the functions of the 900 model

What functions can be derived from a chronograph caliber with a second time zone? How do you fit as many time-based measuring units into an extremely small space? How complex can the design of an instrument chronograph be? The answer to all these questions is our multifunctional chronograph 900.

The starting point for the multifunctional chronograph is the reliable Valjoux 7750 movement with a 24-hour UTC design. The special functions implemented by our engineers on this basis go far beyond what's available in a conventional instrument chronograph. The case und features create the prerequisites for reliable functionality, a long service life and indestructibility.

The combination of all the technologies used in the watch protect it against water, cold, over- and underpressure, magnetic fields and scratches – an all-round protection that makes multifunctional chronograph 900 the ideal timepiece for expeditions. You'll find a more detailed description of the special function scales on the pages “Special Characteristics”.
