MB&F has expanded and updated its popular Legacy Machine 101 collection, which features one of the independent watchmaker’s most compact (40mm) creations and the first to be powered by a movement entirely designed and built by the watchmaker’s own engineering team.
A dramatic suspended balance wheel still dominates the LM101, but this latest design enhances the dial display with a double hairspring. You might recognize the addition: It’s the same hairspring found in the LM101 MB&F x H. Moser collaboration, which sold out quickly after its debut last year.
Reading the time and the power reserve on the new LM101 is also made easier thanks to larger subdials and a slimmer bezel than we’ve seen on previous versions of the watch. Underneath the new hairspring and larger subdials MB&F is offering a new dial for this latest LM101.
In addition to the three new lacquered dial colors, note the new finely engraved sunray pattern, which MB&F places directly on top of the movement plate.
And finally, one of the three LM101 debuts is cased in steel, which MB&F utilizes fairly infrequently as a case material. The debut includes three editions: white gold with a striking purple dial, red gold with a handsome dark blue dial ($68,000) and in a stainless steel case with a light blue dial ($56,000).
