Launched two years ago and a bigger hit than its complexity or price would have predicted, the Legacy Machine Perpetual is MB&F‘s most complicated watch to date, boasting a cleverly constructed perpetual calendar mechanism devised by Irish watchmaker Stephen McDonnell. Having made its debut in white and red gold as well as platinum, it’s now the turn of the LM Perpetual Titanium.

The case is the same size and style, measuring 44mm wide, but now in titanium. That’s matched with a striking metallic green dial, of a similar shade as that found in the LM2 Titanium and LM1 Dubai edition.

The 581-part movement remains the same, with the most interesting bits visible on the front, under the oversized balance wheel that’s a signature of the Legacy Machine series. Almost all of the perpetual calendar mechanism is visible on the dial, and unlike conventional perpetual calendars, it was designed to be robust and easy to set.

Price and availability 

The LM Perpetual Titanium is a limited edition of 50 pieces, priced at US$148,000. It’s available at MB&F retailers and M.A.D Galleries.
