Oris ProPilot X Calibre 400 Laser 39mm Mens Watch

Ref. 01 400 7778 7150-07 7 20 01TLC

The ProPilot X Calibre 400 existed for a year and a half before this version appeared at Dubai Watch Week 2023, and the Laser variant is distinguished by a single, consequential difference: the dial carries no colour pigment whatsoever. Developed with ETH Zürich, the technique uses laser treatment to manipulate the titanium dial surface so that reflected light waves contain only a selected spectrum, producing a shift through blue, green and violet depending on the angle. The inspiration is biomimicry — specifically the iridescent wing structure of certain beetles — and the date complication was quietly dropped to give the effect an uninterrupted field to work across. That alone separates it from most of its ProPilot X siblings. The Calibre 400 underneath is worth understanding on its own terms. Conceived entirely in-house, it runs a twin-barrel design for a 120-hour power reserve, carries over thirty non-ferrous components to exceed ISO 764 anti-magnetic standards comfortably, and is rated to -3/+5 seconds per day with a ten-year service interval to match its ten-year warranty. The rotor uses a low-friction slide bearing rather than a conventional ball-bearing, and the skeletonized caseback makes all of this visible. On the wrist, the 39mm all-titanium build reads larger than the diameter suggests — the turbine-inspired fluted bezel and the integrated bracelet account for that — but the weight keeps it closer to a sport watch than a dress piece.
