AN UNCOMPROMISING CALIBRE
RM 12-01 TOURBILLON
BRIDGES MADE OF GRADE 5 TITANIUM
The baseplate supports the grade 5 titanium bridges, which are highly original in terms of their three-dimensional construction. Extremely stylized, the sharp, streamlined curves of the skeletonized bridges encircling the barrel, the great wheel and the tourbillon radiate to the end of the manual winding caliber.
This exceptional and architectural caliber can withstand accelerations of over 5,000 g’s.
FAST-ROTATING BARREL (6 hours per revolution instead of 7.5 hours)
This type of barrel has the following advantages:
• The phenomenon of periodic internal mainspring adhesion is significantly diminished, thereby increasing performance.
• Provision of an excellent mainspring delta curve with an ideal power reserve/performance and regularity ratio.
FREE-SPRUNG BALANCE WITH VARIABLE INERTIA
A free-sprung balance with variable inertia and a terminal-curve spring better reliability in the event of shocks, movement assembly or disassembly, and guarantees better chronometric results over time.
