Watch manufacturer MB&F is back with an exciting product. This time it comes from the LM Perpetual EVO model, which now touches titanium material.

This introduction coincides with one year of the presence of the Legacy Machine (LM) Perpetual EVO. At that time, EVO marked a significant milestone for MB&F, especially for horological fans. With EVO, the roles were inverted: now the watch followed the path decided by its owner – thanks to a redesigned, sleeker case, ergonomic double-sprung pushers, an integrated rubber strap, Super-LumiNova, a specially developed 'FlexRing' shock-absorbing system, a screw-down crown and 80 meters of water resistance. The result was the most comfortable, robust MB&F Machine to date; "Not just a watch for sports, a watch for life."

Legacy Machine Perpetual EVO was first launched in three variations of 15 pieces each in zirconium with orange CVD dial plate, blue CVD dial plate, or black PVD dial plate; and is now available in titanium with a green CVD dial plate. Watch enthusiasts love this Perpetual EVO model that the zirconium model sells out in three weeks.

Using a case measuring 44 mm, zirconium or titanium materials are considered more luxurious than stainless steel. MB&F designed the LN Perpetual EVO with an open and extreme design at the same time. It features a monobloc shock-absorbing system called FlexRing, which makes this watch engine the toughest in the MB&F brand range. This Machine was designed by Stephen McDonnel and won an award as a perpetual calendar engine with mechanical processor innovation.

When it first came with zirconium material, the LM Perpetual EVO came in three PVD/CVD dial plate color options, including atomic orange, the first time ever on a Swiss-made luxury watch. The new titanium material comes with a green CVD dial plate. All editions use a rubber strap for a pleasant wearing experience.

The MB&F collection has welcomed several complications and horologically prestigious mechanisms over the past 15 years, including the record-smashing TriAx that debuted in 2019's Legacy Machine Thunderdome. In terms of combining prestige, tradition, and innovation, however, Legacy Machine Perpetual has remained at the apex of MB&F watchmaking savoir-faire since it was introduced in 2015.

Although the 44mm diameter is unchanged from its 2015 iteration, the new EVO case design features a no-bezel construction. 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 comprehensive 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.

When Stephen McDonnell set out to redesign the perpetual calendar for MB&F, he proposed a system that rethought the entire mechanical basis of the complication. 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 the correct number of days precisely 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 while the date is changing, there is no risk of damage to the movement.

This watch is sold with a price tag of $176,000 or around Rp 2.4 billion.
