When Breguet launched this Marine Tourbillon Watch 5837 in 2007, it was the first watch with a silicon escapement movement. Not only the balance spring, but also the escapement wheel and fork lever are made of silicon. The tourbillon base is made of titanium. The reason for using this highly innovative material is that these materials can get a lighter tourbillon, so it also has better shock resistance, non-magnetic, and because it requires no lubrication, it is easier to adjust.

 Now at Baselworld 2011, Breguet has added 950 platinum to the original rose gold model. In addition to the new precious metal material as the case, the dial with a water wave pattern is made of gold with silver plating and platinum coating, and all are carved manually by an old-fashioned engraving machine according to the tradition of Breguet.

 The watch is equipped with a cal. 554.4 manual winding chronograph movement. The 30-minute counter at 3 o’clock, the 12-hour counter at 6 o’clock, and the chronograph second hand in the center. The tourbillon mechanism is located at 12 o’clock. Movement diameter 12 law minutes, 28 stone. Provides a 50-hour power reserve at a frequency of 21600vph. The watch is water resistant to 100 meters.
