Oris Watch Big Crown ProPilot Big Day Date. 01 752 7760 4164-07 8 22 Since it produced its first pilots watch in the 1930s, Oris has pioneered a number of innovations that have made it a favourite among flyers. Boasting a cool, clean and classic look, this Oris Big Crown ProPilot Big Day Date watch is no exception and is inspired by the world of aviation, an industry which Oris has had a passion for since birth. The 44mm stainless steel case and coin edged bezel are inspired by powerful jet engine turbines while the clear dial and bold hands are reminiscent of aircraft dashboards and their easy legibility. At the heart of this Oris Big Crown ProPilot Big Day Date watch is the powerful Oris 752 automatic winding movement which equips the timepiece with classic hour, minute and seconds function, an enlarged date and day window at 3 o clock and a power reserve of 38 hours. The striking black dial is housed beneath scratch resistant sapphire crystal glass coated in an anti-reflective treatment and decorated with Arabic numerals and large propeller style hands layered with glow in the dark Superluminova. For the finishing touch, this Oris Big Crown ProPilot is fitted with a sophisticated stainless steel bracelet and a classic folding buckle.
