In 15 years at MB&F, only one Machine has ever been created from yellow gold: the LM101 Frost YG.
And now MB&F is coming back to this beautiful precious metal with the Legacy Machine Perpetual Yellow Gold!
First launched in 2015, the LM Perpetual series is one of our best sellers – awarded Best Calendar Watch at the 2016 Grand Prix (GPHG) – with previous limited editions in white gold, red gold, platinum and titanium. The vast majority of these variations are sold out; it was time to introduce a new 18k yellow gold case with a deep blue face, limited to just 25 pieces.
Developed in collaboration with independent Irish watchmaker Stephen McDonnell, the 581-component LM Perpetual movement completely reinvented the perpetual calendar complication, eliminating the usual drawbacks such as skipping dates or jamming gears. The calibre was designed from scratch for trouble-free, user-friendly use. Its secret? A default 28-day month that adds extra days only as required. But putting aside the remarkable technical aspects of this Machine, it’s the open dial revealing the full complication and suspended balance wheel that really steal the show.
Retail price of the LM Perpetual Yellow Gold is CHF 158,000 + VAT (USD 167,000 or EUR 147,000 + tax).
