Breguet Marine Tourbillon 5837 Wristwatch in Platinum
When it was introduced in 2007, the Marine Tourbillon was the first watch to have a calibre with a silicon escapement. The balance-spring, balance-wheel and lever all used this material.
The tourbillon carriage was made of titanium. The reason for using these ultra-innovative materials was because they made it possible to obtain a tourbillon that was light, and therefore highly shock resistant; non-magnetic; and easier to regulate since it did not require lubrication.
The combination of this prestigious complication, invented by Abraham-Louis Breguet, with a chronograph function, marked the birth of an exceptional watch. Launched as an 18-carat red-gold version in 2007, it is now being introduced with a 950 platinum case.
The matching dial and hands are also of this material, the use of which remains an exception in watchmaking due to the price. Here, the original hands have been replaced by blued-steel Breguet hands.
The dial is still solid gold, entirely covered with hand engraving done on a rose engine in the finest Breguet tradition. Only the finish has been changed, to silvered platinum.
