Reading Time: 2 minutes

Oris has been experimenting with bronze in its diver’s watches for years now, for the first time, the independent Swiss watch company has given its highly competent Big Crown ProPilot Big Date fresh flair by casing it in bronze, too.

The warm tones of the new model come from its bronze case, fluted bezel and signature oversized crown, which are complemented by a deep black dial with printed golden indices. This is a true pilot’s watch, so the hands are filled with white Super LumiNova® and the applied hour markers made from solid Super LumiNova®, creating high contrast and first-class readability.

Finishing off the stylish look is a hard-wearing green Ventile® strap with Oris’s playful ‘ clasp, also in bronze, a device inspired by passenger aircraft seat belt buckles.

As with every Oris, inside the watch is a highly reliable Swiss Made mechanical movement. In this case, that movement is a precision automatic with an oversized ‘ date.
