Rather than a simple second-timezone sub-dial, the ST2557 features a central 24-hour hand that makes one full rotation per day, letting you track a second time zone at a glance alongside the normal hour and minute hands.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eWith 30 jewels and a 21,600vph beat rate, it offers a genuine 40-45 hour power reserve. The dial layout includes small running seconds and a date window, all set within a substantial 45mm, 316L stainless steel case with a screw-down crown and sapphire crystal. Rated to 100m water resistance, it's a genuinely capable everyday watch — comfortable for swimming and daily knocks, though not a certified dive watch in the ISO sense.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThis is a real, functioning GMT complication at a price point where that's genuinely unusual — most affordable \"GMT\" watches use decorative sub-dials rather than a true independently-trackable 24-hour hand.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eCase diameter: 45mm\u003cbr\u003eWater resistance: 100m\u003cbr\u003eCrystal: Sapphire\u003cbr\u003eMovement: Seagull ST2557 automatic GMT, self-winding\u003cbr\u003eCase material: 316L stainless steel\u003cbr\u003eFunctions: True GMT (central 24-hour hand), small seconds, date\u003c\/p\u003e","brand":"Wrist Logic","offers":[{"title":"Blue Green","offer_id":54302397563193,"sku":"14:100005979#Blue Green","price":124.69,"currency_code":"USD","in_stock":true},{"title":"Black Blue","offer_id":54302397595961,"sku":"14:350686#Black Blue","price":114.09,"currency_code":"USD","in_stock":true},{"title":"Black Case \u0026 Blue","offer_id":54302397628729,"sku":"14:200000080#Black Blue","price":119.48,"currency_code":"USD","in_stock":true},{"title":"White","offer_id":54302397661497,"sku":"14:100013777#White","price":115.78,"currency_code":"USD","in_stock":true},{"title":"Black Stealth","offer_id":54302397694265,"sku":"14:200005100#Black Pink","price":129.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0995\/6497\/8489\/files\/Sd75863fb8976400583ba2a0af3c7bba3J.webp?v=1785774474","url":"https:\/\/wristlogic.store\/products\/seakoss-gmt-super-luminous-diving-automatic-mechanical-watch-men-10atm-1963-seagull-st2557-movement-calendar-sapphire-wristwatch","provider":"Wrist Logic","version":"1.0","type":"link"}
