The ProPilot X is where Oris’s modern engineering shows most clearly. It takes the aviation family into lightweight titanium and gives it Calibre 400, the in-house automatic that changed what people expect from the brand.

Calibre 400 is the headline. It stores five days (120 hours) of power, so the watch keeps running over a long weekend on the nightstand, and it was designed with strong resistance to magnetism. Oris backs it with a 10-year warranty when the watch is registered with MyOris and recommends service only every 10 years, a rare promise at any price. You can see the movement through the sapphire window in the screwed titanium caseback.

The 39mm multi-piece titanium case and matching titanium bracelet with folding clasp make it light and comfortable on the wrist, and the cool grey dial suits the industrial material. A screw-down crown gives 100 meters of water resistance.
