Over the past two decades, independent luxury watch brand MB&F has reshaped horology with its dazzling and complex mechanical creations. Now, Maximilian Büsser and friends are at it again with the just-unveiled LM Sequential EVO, the studio’s first-ever chronograph.
Housing the 20th original caliber released by MB&F in 17 years, the LM Sequential EVO is far from your average, run-of-the-mill chronograph. The brainchild of Stephen McDonnell, the man behind MB&F’s perpetual calendar movement, the 585-component LM Sequential EVO movement features two column-wheel chronographs — but the double action is not what sets this watch apart. Rather, it’s the movement’s unique “Twinverter” binary switch that inverts the current start/stop status of each chronograph, allowing for an unprecedented number of timing modes.
The display features two 60-second chronograph registers side-by-side in the center of the skeletonized dial, with corresponding 30-minute counters above each and a time display above 6 o’clock. The right side of the zirconium case looks traditional enough, with a screw-down crown at 3 o’clock and chronograph pushers at 2 and 4. On the left side of the case is where things get interesting, as there are two more chronograph pushers at 10 and 8, along with the aforementioned Twinverter pusher at 9 o’clock. The left and right chronographs can function in four different modes: Sequential Mode, which is a highly capable lap timer, Simultaneous Mode, which functions like a split-seconds chronograph, Independent Mode, which uses the two chronographs entirely separately to time two dissociated events, and Cumulative Mode, which tracks the individual cumulative durations of two discontinuous events.
Measuring 44mm across and boasting a water resistance rating of 80m and a power reserve of 72 hours, the MB&F LM Sequential EVO is available in two distinct colorways: Black on a white rubber strap and Orange on black rubber. Both are available via waitlist on MB&F’s website, where they are priced at 172,000 CHF (~$179,541).
