The joy of mechanics comes to the fore in the new Pro Pilot X Calibre 400, a titanium-cased watch inspired by more than a century of aviation heritage and powered by our five-day automatic. The dial-side is defined first by its 39mm titanium case. The taut, angular lines of the aviation-inspired form are satin and sandblasted, giving the watch its raw, technical look, and complemented by the familiar Pro Pilot bezel and a muscular, sculpted titanium bracelet. The oversized crown is also titanium, and flanked by protectors.
