The LM Perpetual series, one of MB&F’s bestsellers, is now crafted with beautiful Yellow Gold
January 30, 2020: At watchmaker MB&F, the LM Perpetual, since being launched in 2015, has been crafted in red gold, platinum, white gold and titanium. A new 18k yellow gold case with a striking blue face now joins the series: in a limited edition of 25 pieces.
MB&F and independent Irish watchmaker Stephen McDonnell have completely reinvented that most traditional of horological complications: the perpetual calendar. The result is Legacy Machine Perpetual, featuring a visually stunning in-house movement – developed from the ground up to eliminate the drawbacks of conventional perpetual calendars.
LM Perpetual features a fully integrated 581-component calibre − no module, no base movement − with a revolutionary new system for calculating the number of days in each month. And it holistically reinterprets the aesthetics of the perpetual calendar by placing the full complication on dial-free display underneath a spectacular suspended balance. The fully integrated movement of Legacy Machine Perpetual has been designed from scratch for trouble-free use: no more skipping dates or jamming gears, and the adjuster pushers automatically deactivate when the calendar changes.
In an interesting technical twist, that eye-catching balance hovering on high is connected to the escapement on the back of the movement by what is likely to be the world's longest balance staff. Using an innovative system developed especially for Legacy Machine Perpetual, the subdials appear to "float" above the movement with no visible attachments.
The Legacy Machine Perpetual won the Best Calendar Watch Prize at the GPHG (Grand Prix d’Horlogerie de Genève) in 2016.
