Legacy Machine Perpetual EVO is a sporty iteration of their most complex watch, now water-resistant to 80 meters and fitted with a rubber strap. Developed by Irish watchmaker Stephen McDonnell, the LM Perpetual was launched in 2015 to widespread acclaim; it won the Best Calendar Watch award at the 2016 Grand Prix d'Horlogerie de Genève (GPHG).

The LM Perpetual EVO’s production was extremely limited – just 15 pieces were made in each dial plate coated in “atomic orange”, blue, and black. The LM Perpetual EVO uses a case made of Zirconium, a silvery grey metal known for its hypoallergenic and anti-microbial properties. This is also the first MB&F wristwatch fitted with a screw-down crown and is water-resistant to 80 meters. The calendar adjustments are made via pushers that sit in recessed sections on the case band.

This timepiece has a “FlexRing” annular dampener, fitted between the case and the movement, which offers shock resistance along the vertical and lateral axes. Strikingly complex and rare, this is an opportunity for collectors to acquire a one of a kind perpetual calendar.
