Editor's Notes

Oris' 'ProPilot X Calibre 400' watch is a tribute to the house's early creations, when aviators relied heavily on their precision for flying. Made in Switzerland, it's cast from lightweight titanium and centred with a grey dial that coordinates seamlessly with the case and bracelet. It has easy-to-read indices and a convenient date window, while the Super-LumiNova® coating ensures legibility in low light.

We offer a two-year warranty for all working parts and manufacturing faults for luxury watches. For more information, contact one of our experts by emailing watches@mrporter.com
