Independent Irish watchmaker Stephen McDonnell and MB&F have come together to create a new variation of the LM Perpetual watch. The LM Perpetual Stainless Steel is the latest addition to the LM Perpetual family and features a salmon-colored dial, a first for MB&F. The new edition comes with ergonomic corrector pushers that were first introduced in the LM Perpetual EVO editions.
The MB&F LM Perpetual is a complete reinvention of the traditional horological complication, the perpetual calendar. The in-house movement of the LM Perpetual is a fully integrated 581-component caliber that eliminates the drawbacks of conventional perpetual calendars. The perpetual calendar is a great traditional complication that calculates the varying numbers of days in each month, including the leap year.
Traditional perpetual calendars have a few drawbacks; dates can skip, and the complications are usually compromises of modules powered by base movements. The MB&F LM Perpetual features a fully integrated, purpose-built movement that is designed for trouble-free use. It eliminates skipping dates or jamming gears, and the adjuster pushers automatically deactivate when the calendar changes.
The LM Perpetual turns the traditional perpetual calendar system on its head by using a “mechanical processor” instead of the conventional space-consuming grand levier (big lever) system architecture. The subdials of the watch appear to “float” above the movement with no visible attachments. The skeletonized subdials rest on hidden studs, which is technically impossible with traditional perpetual calendar mechanisms. The limited edition MB&F Legacy Machine Perpetual is priced at $180,000.
