Inside the watch’s 42-mm polished and satin-finished rose-gold case is the new manual-winding Caliber BM12-1975M, designed by Baume & Mercier in collaboration with the movement specialists at Manufacture Horlogerie Valfleurier. The movement, which has 18 jewels and a 28,800 vph frequency and boasts a power reserve of 90 hours, is equipped with the exclusive TwinSpir technology, which incorporates a number of technical innovations developed by the Research & Innovation department at Richemont, parent company of Baume & Mercier and a number of other luxury watch brands.
The TwinSpir technology is centered around a newly developed hairspring with a composite structure combining two layers of silicon, alternatively oriented and bound through an extra layer of silicon dioxide, which also acts as a thermo-compensating element. Combined with the movement’s other noteworthy technical element — a newly designed, inertia-type balance wheel— the technology has several benefits, according to Baume & Mercier. These include enhancing the precision of the movement in various positions and over time; limiting the movement’s sensitivity to surrounding magnetism; and ensuring a greater resistance to small shocks and repeated vibrations.
