Limited to 1,500 individually numbered pieces, it is powered by Seiko’s 5X83 caliber, which provides high-speed GPS dual-time and time-zone adjustment across 39 time zones, along with a chronograph capable of measuring elapsed time in 1\/20-second increments. Additional functions include an AM\/PM indicator, daylight-saving-time adjustment, power-save function, a perpetual calendar accurate through 2100, and a time-transfer function that switches the main-time and dual-time displays at the press of a button. Powered by light, the watch requires no battery replacement.\u003c\/p\u003e\n\u003cp\u003eThe watch features a polygonal titanium bezel with a rose-gold finish and a brilliant black sapphire insert, topped by dual-curved sapphire crystal with super-clear coating. Its navy-blue patterned dial has a distinctive texture and improved contrast, while four vertically arranged subdials reinforce its sporty character. A date display and LumiBrite hands and markers provide enhanced visibility in low-light conditions. The lightweight titanium case and bracelet are finished with a super-hard coating, while black ceramic center links add a refined shine. Sleek lines, a slim profile, and a compact angular design give the watch a contemporary appearance. The bracelet is completed by a tri-fold push-button clasp with Seiko’s Smart Adjuster function. The watch is water-resistant to 10 bar, or 100 meters.\u003c\/p\u003e\n\u003cp\u003eLimited edition of 1,500 pieces\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCaliber Number: 5X83\u003c\/li\u003e\n\u003cli\u003eMovement Type: GPS solar\u003c\/li\u003e\n\u003cli\u003ePrecision: ±15 seconds per month (without receiving a GPS signal and at temperatures between 5°C and 35°C)\u003c\/li\u003e\n\u003cli\u003ePower Reserve: Operating for approx. 6 months (when fully charged), power save: approx. 2 years\u003c\/li\u003e\n\u003cli\u003eJewels: 14\u003c\/li\u003e\n\u003cli\u003eOvercharge prevention function\u003c\/li\u003e\n\u003cli\u003ePower save function\u003c\/li\u003e\n\u003cli\u003eChronograph up to 12 hours in 1\/20 second increments\u003c\/li\u003e\n\u003cli\u003ePerpetual calendar to February 28, 2100\u003c\/li\u003e\n\u003cli\u003eWorld time function (38 time zones)\u003c\/li\u003e\n\u003cli\u003eDual-time function (with AM\/PM indication)\u003c\/li\u003e\n\u003cli\u003eDay display\u003c\/li\u003e\n\u003cli\u003ePower reserve indicator\u003c\/li\u003e\n\u003cli\u003eTime transfer function (Switching between the main-dial and sub-dial)\u003c\/li\u003e\n\u003cli\u003eGPS signal reception function (Time zone adjustment, automatic time adjustment, manual time adjustment)\u003c\/li\u003e\n\u003cli\u003eSatellite acquisition status display function\u003c\/li\u003e\n\u003cli\u003eReception result display function\u003c\/li\u003e\n\u003cli\u003eDST (Daylight Saving Time)\u003c\/li\u003e\n\u003cli\u003eFunction to prevent the GPS signal reception (in-flight mode)\u003c\/li\u003e\n\u003cli\u003eAutomatic hand position alignment function\u003c\/li\u003e\n\u003cli\u003eCase Material: Titanium (super hard coating) with sapphire crystal bezel insert\u003c\/li\u003e\n\u003cli\u003eCase Size: Thickness: 14.4mm, Diameter: 44.3mm, Lug-to-lug: 50.0mm\u003c\/li\u003e\n\u003cli\u003eCrystal: Dual-curved sapphire crystal\u003c\/li\u003e\n\u003cli\u003eCrystal Coating: Super-clear coating\u003c\/li\u003e\n\u003cli\u003eLumiBrite: Lumibrite on hands and index(es)\u003c\/li\u003e\n\u003cli\u003eClasp: Three-fold clasp with push button release (with Smart Adjuster function)\u003c\/li\u003e\n\u003cli\u003eWater Resistance: 10 bar (100 meters)\u003c\/li\u003e\n\u003cli\u003eWeight: 115.0g\u003c\/li\u003e\n\u003cli\u003eLIMITED EDITION on the case back\u003c\/li\u003e\n\u003cli\u003eSerial number engraved on the case back\u003c\/li\u003e\n\u003cli\u003eScrew case back\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Seiko","offers":[{"title":"Default Title","offer_id":55518391271796,"sku":"SSH180","price":3300.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2930\/0774\/files\/SSH180.jpg?v=1789031900","url":"https:\/\/topperjewelers.com\/products\/seiko-ssh180","provider":"Topper Fine Jewelers","version":"1.0","type":"link"}
