When the 220.xx Aqua Terra generation launched in 2017 with the Cal. 8900, every standard AT got a successor — except the GMT. Omega simply dropped the complication from the lineup and never looked back, which makes this 43mm reference the last Aqua Terra GMT ever produced. That orphan status gives it a strange position in the catalog: it's the only way to get a true GMT hand on an Aqua Terra case, and the Cal. 8605 — a 38-jewel derivative of the in-house 8500 with a dedicated 24-hour hand and independently adjustable local hour — is a movement that exists in no current-production Omega. The blue teak dial, exhibition caseback, and the slightly larger 43mm case (versus the standard 41.5mm AT of the same generation) give it a presence the time-only models don't carry, and the 21mm lug width sets it apart dimensionally from the 20mm standard.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eKey Details\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCase diameter: 43 mm\u003c\/li\u003e\n\u003cli\u003eCase thickness: 14.15 mm\u003c\/li\u003e\n\u003cli\u003eLug-to-lug: 51.40 mm\u003c\/li\u003e\n\u003cli\u003eLug width: 21 mm\u003c\/li\u003e\n\u003cli\u003eWeight: ~176 g on bracelet\u003c\/li\u003e\n\u003cli\u003eCase material: 316L stainless steel, brushed and polished\u003c\/li\u003e\n\u003cli\u003eCrystal: domed sapphire, anti-reflective treatment both sides\u003c\/li\u003e\n\u003cli\u003eWater resistance: 150 m \/ 15 bar\u003c\/li\u003e\n\u003cli\u003eCaseback: transparent\/exhibition (sapphire)\u003c\/li\u003e\n\u003cli\u003eBezel: fixed, smooth, polished stainless steel\u003c\/li\u003e\n\u003cli\u003eCrown: screw-in\u003c\/li\u003e\n\u003cli\u003eDial: blue, sun-brushed and lacquered, horizontal \"teak concept\" vertical stripe pattern\u003c\/li\u003e\n\u003cli\u003eHands\/indexes: silver-toned, luminous (hour, minute, seconds, GMT hand)\u003c\/li\u003e\n\u003cli\u003eDate: 6 o'clock, semi-instantaneous jump\u003c\/li\u003e\n\u003cli\u003eGMT: dedicated 24-hour hand, independently adjustable local hour hand\u003c\/li\u003e\n\u003cli\u003eCaliber: Omega 8605 (in-house, based on Cal. 8500)\u003c\/li\u003e\n\u003cli\u003eMovement type: self-winding automatic, 3-level Co-Axial escapement\u003c\/li\u003e\n\u003cli\u003eFrequency: 25,200 vph \/ 3.5 Hz\u003c\/li\u003e\n\u003cli\u003eJewels: 38\u003c\/li\u003e\n\u003cli\u003ePower reserve: 60 hours, dual mainspring barrels\u003c\/li\u003e\n\u003cli\u003eBalance: free sprung, 4 regulating screws, silicon Si14 balance spring\u003c\/li\u003e\n\u003cli\u003eAnti-magnetic: not rated (Version A); \u0026gt;15,000 gauss (Version G, post-~2015)\u003c\/li\u003e\n\u003cli\u003eCertification: COSC Chronometer (all); METAS Master Chronometer (Version G only)\u003c\/li\u003e\n\u003cli\u003eBracelet: stainless steel, brushed and polished\u003c\/li\u003e\n\u003cli\u003eClasp: butterfly deployment\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Omega","offers":[{"title":"Default Title","offer_id":46054821658703,"sku":"598Q5","price":9110.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0636\/1733\/5375\/files\/c4563b865f400987ede26653a881b116.jpg?v=1784069996","url":"https:\/\/kingdomwatchcompany.com\/fr\/products\/omega-seamaster-aqua-terra-gmt-discontinued-dated-2025-complete-set","provider":"Kingdom Watch Company","version":"1.0","type":"link"}
