Introduced in 2013 alongside the GoodPlanet edition, this was the first Planet Ocean to carry a true GMT complication, and it did so with a fully in-house engine rather than a modified ETA base. That distinction matters.\u003cbr\u003eAt the heart of this thing sits the Calibre 8605, derived from the landmark 8500 movement family that Omega positioned as its modern flagship architecture. It runs a three-level Co-Axial escapement — the mature, problem-free evolution that left the early Calibre 2500 teething issues far behind — paired with a silicon Si14 balance spring on a free-sprung balance, dual barrels in series for a stable 60-hour power reserve, and a jumping hour hand that makes independent time-zone adjustments clean and mechanical rather than fiddly. COSC-certified, naturally. Visible through the exhibition caseback, the rhodium-plated bridges and arabesque Geneva waves are finished to a standard that punches well above the price point.\u003cbr\u003eOn the wrist, this is a 43.5mm tool watch that actually commits to being a tool watch. 600 meters of water resistance with a helium escape valve, a polished black ceramic bezel with a full 24-hour GMT scale in LiquidMetal, and a lacquered black dial with applied luminous indices and Arabic numerals at the cardinal positions. The orange-tipped GMT hand reads against the bezel scale at a glance — no ambiguity, no squinting. It's a diver, a travel watch, and a daily-wear piece all at once, and it doesn't compromise on any of those jobs to serve the others.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eKey Details\u003cbr\u003eCase \u0026amp; Exterior\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eCase diameter: 43.5 mm\u003cbr\u003eCase thickness: 17.25 mm\u003cbr\u003eLug-to-lug: 49.2 mm\u003cbr\u003eLug width: 21 mm\u003cbr\u003eTotal weight: 217 g (on bracelet)\u003cbr\u003eCase material: Stainless steel, brushed and polished\u003cbr\u003eBezel: Unidirectional rotating, polished black ceramic insert with 24-hour GMT scale\u003cbr\u003eCrystal: Domed sapphire, scratch-resistant, anti-reflective treatment on both sides\u003cbr\u003eCaseback: Transparent sapphire exhibition\u003cbr\u003eCrown: Screw-down\u003cbr\u003eHelium escape valve: Yes\u003cbr\u003eWater resistance: 600 meters \/ 2000 feet (60 bar)\u003cbr\u003eBracelet: Stainless steel, brushed, with fold-over push-button deployant clasp\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eDial\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eDial color: Black lacquered\u003cbr\u003eHour markers: Applied luminous indices with Arabic numerals at 6, 9, and 12\u003cbr\u003eHands: Luminous silver-tone hour and minute hands; orange-tipped central GMT hand\u003cbr\u003eDate display: Window at 3 o'clock\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eMovement\u003cbr\u003e\u003cbr\u003e\u003cbr\u003eCalibre: Omega 8605\u003cbr\u003eType: Automatic (self-winding), in-house\u003cbr\u003eEscapement: 3-level Co-Axial\u003cbr\u003eFrequency: 25,200 vph (3.5 Hz)\u003cbr\u003eJewels: 38\u003cbr\u003ePower reserve: 60 hours\u003cbr\u003eBalance spring: Silicon Si14, free-sprung balance\u003cbr\u003eWinding: Bi-directional automatic via dual barrels in series\u003cbr\u003eFunctions: Hours, minutes, seconds (hacking), date, GMT \/ second time zone (jumping hour hand)\u003cbr\u003eCertification: COSC Chronometer\u003cbr\u003eFinish: Rhodium-plated bridges and oscillating mass, Geneva waves in arabesque pattern\u003c\/p\u003e","brand":"Omega","offers":[{"title":"Default Title","offer_id":46048202850383,"sku":"667A6","price":5385.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0636\/1733\/5375\/files\/88f058d61b12e931a50192016c7b2c43.jpg?v=1783981674","url":"https:\/\/kingdomwatchcompany.com\/fr\/products\/2025-omega-seamaster-planet-ocean-gmt-complete-set","provider":"Kingdom Watch Company","version":"1.0","type":"link"}
