What hasn’t changed is the caliber, aside from the increased power reserve and the new FlexRing surrounding it. The LM101 Caliber, upon its introduction in 2014, was the brand’s first in-house caliber, designed alongside the legendary watchmaker Kari Voutilainen. As a result, its large, sweeping bridges, gold chatons, and wide Geneva stripes remain the same on the caseback. It’s this tribute to classic watch finishing that earns the “Legacy” in “Legacy Machine.” The flying balance wheel continues to use Moser’s Straumann double hairspring, beating away at a leisurely 18,000 VpH, or 2.5Hz.
