It allows for a comfortable fit at all times, accommodating changes in wrist size during diving and daily life.\u003c\/p\u003e\n\u003cp\u003eThis 1968 Heritage reference is still powered by Seiko's own Caliber 6R54, which features a GMT function that allows it to display the time in two different time zones. The watch’s specifications have been enhanced to offer 300-meter water resistance. And while the watch’s design reflects its heritage, every aspect of this new creation is fully up to date in specification and execution. The case design is inherited from the 1968 original, and the case sides are mirror finished. The edge of the unidirectionally rotating bezel offers easy control. \u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFunctions: Hours, minutes, seconds, date, GMT on 24-hour scale\u003c\/li\u003e\n\u003cli\u003eMaterial: Stainless steel\u003c\/li\u003e\n\u003cli\u003eBezel: Uni-directional rotating with ceramic 60-minute diver insert\u003c\/li\u003e\n\u003cli\u003eDimensions: 42mm (13mm thick)\u003c\/li\u003e\n\u003cli\u003eFront Crystal: Curved sapphire\u003c\/li\u003e\n\u003cli\u003eDial: Applied hour markers with LumiBrite luminous paint\u003c\/li\u003e\n\u003cli\u003eCaliber: 6R54 automatic with GMT\u003c\/li\u003e\n\u003cli\u003eWater Resistance: 200 meters\u003c\/li\u003e\n\u003cli\u003eLug width: 20mm\u003c\/li\u003e\n\u003cli\u003eStrap: Stainless steel bracelet with three-fold clasp \u0026amp; secure lock, push button release with extender\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e","brand":"Seiko","offers":[{"title":"Default Title","offer_id":54766326612340,"sku":"HBC002","price":1700.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2930\/0774\/files\/seiko-prospex-HBC002-topper.png?v=1780979234","url":"https:\/\/topperjewelers.com\/products\/seiko-hbc002","provider":"Topper Fine Jewelers","version":"1.0","type":"link"}
