Baume et Mercier shows off its own mechanical self-winding calibre in five Clifton models

Speaking of exciting news:  

Baume et Mercier now has its own calibre. 

Named the Baumatic BM12-1975A calibre, the new movement was created in partnership between Manufacture Horlogère ValFleurier and the research  

and innovation teams at Richemont Group. 

The new mechanical self-winding calibre specifically targets four areas that concern the user experience the most: sensitivity to magnetic fields; chronometric precision (accuracy); autonomy (power reserve) and durability (frequency of watch servicing). 

What ensued was out-of-the-box thinking. It houses a silicon hairspring enhanced with Richemont Group’s proprietary TWINSPIR technology. The anchor and the escape wheel are also made of silicon,  enhancing efficiency while reducing the need for frequent servicing. 

The escapement is  improved with POWERSCAPE technology, which uses a uniquely designed anchor and escape wheel, and when paired with an optimised barrel, offers an impressive 120-hour or 5-day power reserve. 

The use of silicon helps enhance its anti-magnetic properties to at least 1,500 Gauss (a watch is considered to be anti-magnetic if it withstands magnetic field of 60 Gauss).

Silicon also helps improve precision in timekeeping, as it is resistant to corrosion. The movement is COSC-certified, only losing or gaining precision by -4 to +6 seconds per day. 

To enhance durability, the movement is lubricated using Richemont’s own oils developed by its research and innovation teams. 

The new Baumatic movement is housed in five 40mm Clifton models, all featuring a transparent caseback to show off the new Baumatic calibre.
