First presented in 2020, the MB&F LM Perpetual EVO was first released with a zirconium case and three dial plates in PVD/CVD colors, including black, blue, and atomic orange. A year later, a titanium edition with a green CVD dial plate followed. Now in 2024, MB&F is adding 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.
Although the 44 mm case diameter is unchanged from its 2015 iteration, the new LM Perpetual EVO case design features a no-bezel construction, with the domed sapphire crystal fused directly to the case. The increased openness of this design highlights the equilibrium between the legibility of LM Perpetual EVO’s calendar indications and the cinematic play of the engine components — surmounted by the iconic MB&F hovering balance wheel.
This expansive new presentation of the LM Perpetual Engine was no simple design reconfiguration. New geometries for the sapphire crystal had to be calculated, achieving the mechanically opposing aims of maintaining structural strength and decreasing its height-to-diameter ratio. Freeing LM Perpetual EVO from the bezel also necessitated the use of a sophisticated thermal bonding system between the sapphire crystal and the case. Additionally, the previously circular pushers for adjusting the perpetual calendar have been enlarged into double-sprung oblong actuators, boosting tactile comfort and ease of adjustment. The LM Perpetual EVO is rated at 80 meters 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.
An additional new element of the LM Perpetual EVO is the FlexRing: an annular dampener fitted between the case and movement, providing shock protection along the vertical and lateral axes. Machined from a single block of stainless steel, the dampener imparts exceptional robustness to the perpetual calendar, a function that is associated with classicism and elegance, but is arguably the most pragmatic and utilitarian of all the high complications.
It is time for that Titanium/Green combo to retire and to be replaced by a new edition Perpetual EVO in titanium with an icy blue dial plate.
It is time for that Titanium/Green combo to retire and be replaced by the new LM Perpetual EVO BLUE, in titanium with a light blue dial plate. The new MB&F LM Perpetual EVO Icy Blue is delivered on a white rubber strap with a titanium folding buckle.
