When you love mechanical watches, do you begin your critique of a new piece looking at the case front or back? The new ProPilot X Calibre 400 is designed to inspire joy no matter what angle you come at it from.

The dial-side is defined first by its 39mm titanium case. The taut, angular lines of the aviation-inspired form are satin and sand- blasted, giving the watch its raw, technical look, and complemented by the familiar ProPilot bezel and a muscular, sculpted titanium bracelet. The oversized crown is also titanium, and flanked by protectors.

Beyond, the launch collection offers a choice of three dial colours: grey, blue and salmon. This is a fresh, expressive palette, chosen to augment the cases dynamic proportions C and to bring life and colour to your wrist.
