The MB&F LM Perpetual LM3 ref. 03.WL.P is an exceptional timepiece resulting from a collaboration between MB&F and independent watchmaker Stephen McDonnell. This intensely innovative perpetual calendar timepiece combines contemporary aesthetics and traditional craftsmanship in such a way that is truly revolutionary, much like so many MB&F timepieces that have come before it. First launched in 2015, the Legacy Machine Perpetual LM3 has become a signature within MB&F’s offering thanks to its unconventional and legible display that features the calendar indications—day, date, and month—and a subtle leap year indication within the three sub-dials that are integrated within the Stephen McDonnell-designed movement. This in-house, hand-wound movement has a 72-hour power reserve and is encased within a palladium case that measures 44mm in diameter and 17.5mm in height. With its visually striking suspended balance wheel, which oscillates at 18,000 vibrations per hour, showcasing the ingenuity and artistic vision of MB&F and Stephen McDonnell, the MB&F LM3 ref. 03.WL.P and all of its sister variants are a remarkable fusion of cutting-edge design and traditional watchmaking expertise, featuring a unique perpetual calendar mechanism, captivating aesthetics and craftsmanship that pays homage to “19th century style” as MB&F puts it themselves. This particular 18kt white gold variant, launched in 2016 with a rich purple display, is limited to 25 pieces and features the older-style pushers that are smaller and more discreet when compared with the new EVO iteration that feature a larger square design.

A watch filled with MB&F's intensely unique aesthetic and abundantly novel mechanical merriment, the LM Perpetual showcases how MB&F can take a slightly more conservative design language than they are typically known for and make it entirely their own.
