Oris Watch Big Crown ProPilot Big Date. 01 751 7761 4065-07 6 20 08LC Since they produced their first pilots watch in the 1930s, Oris has pioneered a number of innovations that have made them a favourite among flyers. Boasting a cool, clean and classic look, this Oris Big Crown ProPilot Big Date watch is no exception and is inspired by the world of aviation, an industry that Oris has had a passion for since birth. The 41mm 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 Date watch is the powerful Oris 751 automatic winding movement which equips the timepiece with classic hour, minute and seconds function, an enlarged date window at 3 o clock and a power reserve of 38 hours. The striking blue dial is housed beneath scratch resistant sapphire crystal glass treated with an anti-reflective coating 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 black calfskin leather strap and a stainless steel folding buckle.
