From a purposeful standpoint, the watch has a 30-minute chronograph counter situated at three o’clock, with a operating seconds counter positioned at 9 o’clock. That is all powered by the hand-wound MB M13.21 motion – the current-day descendent of the Minerva Calibre 13.20 – seen by means of a show caseback. Practically each element of the motion – aside from jewels and a handful of screws – was made in-house in Villeret. With a 60-hour energy reserve, the motion has a screw stability with Philips curve, Rhodium-coated German silver bridges with Côtes de Genève, round graining on either side, and hand-chamfered edges.
