This hand-wound movement features a generous 10-day power reserve, exceptional compared to most mechanical watches. This is fueled by a mainspring in an oversized barrel, visible through the sapphire case back. The remaining power is displayed through a non-linear indicator at 3 o'clock, which is another innovation in itself, as it is driven by a \"worm gear\" unique to Oris.\u003c\/p\u003e\n\u003cp\u003eFirst introduced in 1938 as a pilot’s watch, the Big Crown has been a collection mainstay ever since, becoming Oris’s signature design. Its oversized crown was originally intended for gloved airmen but now serves a more aesthetic purpose, and a reminder of its inventiveness and purpose-built origins.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMovement: Oris Calibre 113 (handwound)\u003c\/li\u003e\n\u003cli\u003eFunctions: Centre hands for hours \u0026amp; minutes, small seconds indicator at 9H, day, date, month aperture, 52-week pointer\u003c\/li\u003e\n\u003cli\u003ePower Reserve: 10 days\u003c\/li\u003e\n\u003cli\u003eCase: Stainless steel case\u003c\/li\u003e\n\u003cli\u003eSize: 43mm\u003c\/li\u003e\n\u003cli\u003eDial: Green with hands and hour markers coated with Superluminova C1\/C3\u003c\/li\u003e\n\u003cli\u003eCrystal: Sapphire, domed on both sides, anti-reflective coating inside\u003c\/li\u003e\n\u003cli\u003eCase Back: Screwed, exhibition sapphire glass\u003c\/li\u003e\n\u003cli\u003eWater Resistance: 5 bar (50 meters)\u003c\/li\u003e\n\u003cli\u003eStrap: Stainless steel bracelet with folding clasp (21mm lug width)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Oris","offers":[{"title":"Default Title","offer_id":53257630777716,"sku":"01 113 7800 4057-07 8 21 06","price":500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2930\/0774\/files\/oris-big-crown-113-topper.png?v=1757105723","url":"https:\/\/topperjewelers.com\/products\/oris-01-113-7800-4057-07-8-21-06","provider":"Topper Fine Jewelers","version":"1.0","type":"link"}
