When this Marine Tourbillon watch was launched 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 does not require lubrication, it is easier to adjust. The combination of this famous composite mechanism invented by Master Abraham-Louis Breguet has the function of a chronograph, marking the birth of a great generation of watches. The 18K rose gold model debuted in 2007, and now Breguet is about to introduce a 950 platinum case. The matching dial and hands also use this material, because it is expensive, so this material is also unique in the watchmaking industry. Here, the original pointer has been replaced with (Breguet) blue steel pointer. The dial is still made of pure gold, all carved by hand with a rose engine in accordance with the tradition of Breguet. Only the finishing touches changed to silver-plated platinum.
