H76736730) is a technical pilot's chronograph that combines Hamilton's long-standing aviation heritage with a sophisticated set of flight-inspired functions. Its substantial 44mm stainless steel case is finished in black PVD, giving the watch a distinctly modern, tactical appearance. The black dial is framed by a bi-directional rotating slide-rule bezel, allowing the wearer to perform aviation-style calculations and conversions directly from the wrist. Rose-gold-tone hands and applied markers add contrast to the predominantly black design, while luminous detailing ensures strong legibility in low-light conditions. A day-and-date display sits at three o'clock, complemented by the three-register chronograph layout for measuring elapsed time.\u003c\/p\u003e\n\u003cp\u003eInside, the watch is powered by Hamilton's automatic H-21-Si movement, an advanced chronograph caliber equipped with a silicon balance spring for enhanced resistance to magnetic fields and demanding environmental conditions. The movement provides an impressive 60-hour power reserve and drives the chronograph's 60-second, 30-minute, and 12-hour counters. A scratch-resistant sapphire crystal protects the dial, while the screw-down crown and 100-meter water resistance provide additional durability for everyday wear. The watch is finished on a black leather strap with a pin buckle, completing a versatile aviation-inspired package that works equally well as a technical instrument or a distinctive daily-wear sports watch.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eReference Number: H76736730\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eCase: 44mm stainless steel case with black PVD coating\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eBezel: Bi-directional rotating slide-rule bezel\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eDial: Black dial with rose-gold-tone hands and markers, day and date display at 3 o'clock, three-register chronograph\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eCrystal: Sapphire crystal\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eMovement: Hamilton Caliber H-21-Si, automatic, 60-hour power reserve\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eFunctions: Hours, Minutes, Small Seconds, Chronograph, Day and Date, Tachymeter, Slide-Rule Calculator\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eWater Resistance: 100 meters (10 bar)\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eBracelet: Black leather strap with stainless steel pin buckle\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eBox and Papers: Original box and papers included, papers dated 10\/25\/2025\u003c\/span\u003e\u003c\/p\u003e","brand":"Pre-Owned Hamilton","offers":[{"title":"Default Title","offer_id":44762212171818,"sku":"10-20-36852","price":1700.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0014\/5686\/5316\/files\/baf50c44-c982-4b7e-bbda-a19c1c621873.jpg?v=1787938338","url":"https:\/\/www.manfredijewels.com\/products\/pre-owned-hamilton-khaki-aviation","provider":"Manfredi Jewels","version":"1.0","type":"link"}
