The 42mm stainless steel case measures 13.3mm thick with a 48.6mm lug-to-lug span and features the 4 o'clock screw-down crown placement inherited from the 1968 original. Mirror-finished case sides contrast with brushed surfaces, and a unidirectional rotating bezel with a deep green ceramic insert matches the sunray green dial. Applied LumiBrite-filled indices, faceted hands, and a red-tipped lollipop seconds hand combine with a gold-toned GMT hand for at-a-glance dual time-zone reading. Powered by Seiko's in-house Caliber 6R54 automatic GMT movement with manual winding, 24 jewels, 21,600 vibrations per hour, and approximately 72 hours of power reserve. A sapphire crystal protects the dial, and water resistance is rated to 300 meters. The stainless steel bracelet features the new six-step micro-adjust clasp first introduced on the Marinemaster, allowing approximately 15mm of incremental adjustment for comfort across changing wrist conditions.\u003c\/p\u003e","brand":"Seiko Luxe","offers":[{"title":"Default Title","offer_id":49241565855986,"sku":"C0938588","price":1700.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0717\/7843\/5314\/files\/HBC001_1_c49ed860-70a7-4af0-88a7-7764f5a2b9cb.png?v=1779369654","url":"https:\/\/kingjewelers.com\/products\/seiko-prospex-1968-heritage-diver-gmt-hbc001-green-dial","provider":"King Jewelers","version":"1.0","type":"link"}
