First presented in 2015, the MB&F LM Perpetual is one of the MB&F’s absolute superstars. This watch was awarded the Best Calendar Watch prize at the 2016 Grand Prix d'Horlogerie de Genève and since 2015, various limited editions have been announced including several series of 25 pieces in platinum, rose gold, white gold, yellow gold, and in palladium with an aquamarine dial. Additionally, the last LM Perpetual was released in a 50-piece limited edition in titanium with a blue-greenish dial.

Now, MB&F is adding a stainless steel version with a salmon-colored dial which is one of the most unique combinations presented by the brand. Over the last 18 years, they have rarely crafted cases in stainless steel, and only once they have created a salmon dial. Also, this unique combination is not a limited edition but will be limited by production.

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 a dial-free display underneath a spectacular suspended balance.

With its open dial revealing the full complication and suspended balance, it's the harmonious mechanical beauty of LM Perpetual that really steals the show. And in an interesting technical twist, that eye-catching balance hovering on high is connected to the escapement on the back of the movement by what is likely to be the world's longest balance staff. 

Using an innovative system developed especially for Legacy Machine Perpetual, the subdials 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 because they would block the movement of the grand levier. Taking a clockwise tour of the dial, at 12 o'clock we see the hours and minutes nestled between the elegant arches of the balance; day of the week at 3 o'clock, power reserve indicator at 4 o'clock, a month indicator at 6 o'clock, retrograde leap year indicator at 7 o'clock, and date at 9 o'clock. The new MB&F Legacy Machine Perpetual Stainless Steel Salmon Dial is available via the MB&F Authorized Dealer network and through their e-shop.
