MB&F - Legacy Machine Perpetual Stainless Steel

MB&F presented the new LM Perpetual in Stainless Steel with a Salmon Dial. The new Legacy Machine Perpetual in Steel has a price of CHF164,000

Following various versions in red gold, platinum, white gold, titanium, yellow gold and palladium, the Legacy Machine Perpetual has been presented by MB&F in a new variation crafted from stainless steel with a striking salmon-coloured dial, a combination which is a first for the Swiss brand.

The LM Perpetual Stainless Steel will not formally be a limited edition, although it will be limited by the production capacity due to the extreme complexity of this 581-component timepiece.

Its 44 mm x 17.5 mm case inherits the ergonomic corrector pushers that MB&F first introduced in 2020 with the sporty Legacy Machine Perpetual EVO.

Protected by a high domed sapphire crystal treated with anti-reflective coating on both faces, the perpetual calendar complication can be fully appreciated on the dial-free display underneath a spectacular 14 mm suspended balance that beats at 18,000 vibrations per hour (2.5 Hz) delivering an enchanting spectacle.

The hours and minutes subdial is placed at 12 o’clock, between the elegant arches of the balance. The other indications are: day of the week at 3 o’clock, power reserve indicator at 4 o’clock, month at 6 o’clock, retrograde leap year indicator at 7 o’clock, and date at 9 o’clock.

Using an innovative system developed especially for Legacy Machine Perpetual, the subdials appear to “float” above the movement with no visible attachments. The skeletonised subdials rest on hidden studs, which is technically impossible with traditional perpetual calendar mechanisms because they would block the movement of the grand levier.

The Legacy Machine Perpetual uses a unique mechanical processor for its perpetual calendar mechanism. Unlike traditional mechanisms that assume all months have 31 days and discard excess dates for shorter months, this watch assumes all months have 28 days and adds days as needed. This results in each month having precisely the required number of days without skipping or fast-forwarding any days.

In addition to this, the watch also has a quickset pusher for easily adjusting leap years, and its adjuster pushers are automatically deactivated when the calendar changes to prevent any potential problems with the mechanism.

The transparent case back showcases the superlative finishes of this hand wound movement - including polished bevels, Geneva waves and hand-made engravings - as well as the double mainspring barrels guaranteeing a power reserve of 72 hours.

Water resistant up to 30 metres / 100 feet, the new MB&F Legacy Machine Perpetual in Stainless Steel with salmon-coloured dial has a price of CHF 164,000 plus VAT / Euro 172,000 plus VAT / US$ 180,000. mbandf.com
