The LM Perpetual features a fully integrated 581-component calibre − no module, no base movement − with a revolutionary new system for calculating the number of days in each month. And it holistically reinterprets the aesthetics of the perpetual calendar by placing the full complication on dial-free display underneath a spectacular suspended balance. Bringing together the horological complexity and craftsmanship of the innovative perpetual calendar mechanism created by Stephen McDonnell with the bold sophistication of colorful gemstones, these new editions are limited to just 8 pieces each – making them among the rarest LM Perpetuals ever crafted.
