MB&F LM Perpetual EVO Now Comes In An Icy-Blue Edition

MB&F creations have transported their wearers to destinations that exist only on maps of the imagination, from star-cruisers to deep-sea jellyfish.

The LM Perpetual EVO was initially launched in three limited editions in zirconium, followed by a titanium edition with green CVD dial-plate. In 2024, MB&F introduces a new icy blue dial-plate in the same highly-resistant titanium case, replacing its green predecessor. All editions feature a closely-fitted, integrated rubber strap for the smoothest wearing experience of any MB&F Machine ever.

A 44mm case in zirconium or titanium, modern metals with material properties surpassing stainless steel. A case profile that emphasises openness and extreme clarity. A specially developed monobloc shock-absorbing system – “FlexRing” – that makes for the most robust Machine ever to emerge from MB&F. The LM Perpetual Engine, designed by Stephen McDonnell, an award-winning perpetual calendar that replaces traditional constructions with an innovative mechanical processor.

The previously circular pushers for adjusting the perpetual calendar have been enlarged into double-sprung oblong actuators, boosting the tactile comfort and ease of adjustment. The LM Perpetual EVO is rated at 80m of water resistance, enabled by its screw-down crown. A small, but essential, detail of implementing a screw-down crown is the débrayage of the winding stem, disengaging the crown from the winding mechanism when it is pushed in and tightened, which eliminates the chance of manually over-winding the mainspring barrel.

The LM Perpetual uses a “mechanical processor” consisting of a series of superimposed disks. This revolutionary processor takes the default number of days in the month at 28 — because, logically, all months have at least 28 days — and then adds the extra days as required by each individual month. This ensures that each month has exactly the right number of days, and removes the possibility of the date jumping incorrectly. An inbuilt safety feature disconnects the quickset pushers during the date changeover, so that even if the pushers are accidentally actuated whilst the date is changing, there is no risk of damage to the movement.

In design, in technique, in spirit, Legacy Machine Perpetual EVO has been an evolution of your story with MB&F.

The LM Perpetual EVO is not a watch for sports. It is a watch for life.
