BASELNEWS 2011 With a 950 platinum case: Breguet Marine Tourbillon 5837
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.
