MB&F Legacy Machine No. 1 caliber in the MB&F LM101 Frost watch announced April 16, 2015.

Bespoke 14mm balance wheel with four traditional regulating screws floating above the movement and dials.

The smaller in-house LM101 is not to be confused with the MB&F caliber LM1, which was developed in collaboration between MB&F’s own engineering team and other watchmaking friends. The best way to distinguish the two is that the LM101 (seen here) has a single time zone and the LM1 has dual time zones.
