MB&F - Legacy Machine Perpetual EVO Titanium

0 0 Wednesday, 20 October 2021 Edit this post

Last year, MB&F introduced a sportier version, identified by the EVO suffix, of its acclaimed Legacy Machine Perpetual, thus bringing to the market their most robust and water resistant timepiece (we wrote about it here).

In 2021, the Geneva-based brand is presenting the second edition of this model, the Legacy Machine Perpetual EVO Titanium or, in abbreviated form, the LM Perpetual EVO Titanium.

Compared to the traditional LM Perpetual, the EVO version comes with a redesigned, sleeker case, ergonomic double-sprung pushers, an integrated rubber strap, Super-LumiNova-enhanced hours and markers, a specially developed shock-absorbing system, and a 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.

After a first edition with a case in zirconium, the new version is crafted from Grade 5 titanium, an alloy that offers a brighter appearance compared to Grade 2 titanium.

Measuring 44 mm in diameter and 17.5 mm of thickness (crystal glass included), the case has no bezel in order to leave space to the stunning dial with all the calendar indications and the sculptural suspended balance slowly beating at 18,000 vibrations per hour with an autonomy of 72 hours. The domed sapphire crystal is fused directly to the case using a sophisticated thermal bonding system.

The FlexRing is an annular dampener in stainless steel fitted between case and movement to guarantees 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.

For its perpetual calendar MB&F implemented a solution that solves some limitations of traditional perpetual calendar mechanisms that use a 31-day month as the default and "delete" superfluous dates for the months with fewer days by fast-forwarding through the redundant dates during changeover.

Instead, the LM Perpetual makes use of a mechanical processor that utilises a default 28-day month and adds extra days as required. This means that each month always has the exact number of days required; there is no fast-forwarding or skipping redundant days.

The transparent caseback reveals Haute Horlogerie finishes at the highest standards with internal bevel angles, polished bevels, Geneva waves and hand-made engravings.

Matched to a black rubber strap with titanium folding buckle, the new MB&F Legacy Machine Perpetual EVO Titanium edition retails for CHF 152,000 + VAT / EUR 142,000 + tax / USD 176,000. mbandf.com
