Golden Legacy: MB&F Unveils Legacy Machine Perpetual in Yellow Gold Limited Edition

Since its introduction in 2015 - and subsequent award for Best Calendar Watch at the 2016 GPHG - MB&F's Legacy Machine Perpetual has run the gamut of case materials in its various incarnations, all of them very limited in number - rose gold, white gold, platinum, and titanium For the latest, founder Max Büsser and his talented team of "Friends" have turned to a more classical precious metal, 18k yellow gold, pairing it with an of-the-moment blue dial for the latest 25-piece limited edition of the LM Perpetual Designed and developed in cooperation with Irish independent watchmaker Stephen McDonnell, the Legacy Machine Perpetual not only boasts a high-complication movement built entirely from the ground up - no base caliber, no module - but also puts its revolutionary design on full display on the dial side, ensconced beneath a large suspended balance.

The manually wound, 581-part caliber in the LM Perpetual differs from traditional perpetual calendar movements in a few significant respects Traditional perpetual calendar mechanisms can also be easily damaged if the owner makes an inadvertent adjustment while the date is changing; in MB&F's caliber, the adjustment pushers automatically deactivate during calendar changes, so this risk is avoided The movement accomplishes these feats with the use of a "Mechanical processor" in place of the grand levier system more commonplace in perpetual calendar calibers, which also drives the leap-year adjustment by means of a simple quick-set pusher.

Moving clockwise around the dial, the three other skeletonized subdials, mounted on hidden studs, display the day of the week at 3 o'clock, the month at 6 o'clock, and the date at 9 o'clock. . Source
