Engaged in a constant quest for quality, Baume & Mercier introduces its first in-house mechanical self-winding calibre, the Baumatic BM12-1975A, pushing back the existing limits of efficiency and reliability. The advent of the Baumatic movement represents first combined introduction of a silicon balance-spring and a high-performance escapement. Antimagnetic, three times lighter than the ordinary alloys used for hairspring, resistant to corrosion and less sensitive to small impacts and repeated vibrations, silicon enables spectacular progress in terms of horological innovation. Despite its intrinsic qualities, a watch is impacted by a number of inherent and external factors that can inconvenience its user. With the Baumatic BM12-1975A calibre, Baume & Mercier is enhancing the user experience in four key sensitive areas.
