Calibre 135 - 98.1865.0135\/21.C205","description":"\u003cp\u003eThe ZENITH G.F.J. takes the revival of the legendary Calibre 135 into a far more exclusive territory, limited to just 20 pieces. This manual-winding movement is COSC-certified and runs at 18,000 VpH (2.5 Hz), offering a 72-hour power reserve along with a Breguet hairspring and stop-second mechanism for precise setting. It’s a pure expression of chronometry, combining historic architecture with modern refinements for accuracy within ±2 seconds per day.\u003c\/p\u003e\n\u003cp\u003eIts 39.15mm case is crafted from tantalum, a rare and highly demanding metal known for its density, durability, and distinctive blue-grey tone. The dial follows a restrained, architectural design: a deep black onyx center, a grey mother-of-pearl small seconds counter at 6 o’clock, and a brick-pattern guilloché outer ring. Trapeze-cut diamond hour markers (0.45 cts, F-G quality) and 18-ct white gold faceted hands add a precise, refined brilliance without overpowering the monochrome aesthetic.\u003c\/p\u003e\n\u003cp\u003eThrough the sapphire caseback, the Calibre 135 is displayed with Côtes de Genève finishing and a dark ruthenium treatment that mirrors the tone of the case. Water-resistant to 5 ATM, the watch comes with a blue nubuck alligator strap, plus additional black alligator and grey calfskin options, secured with a titanium pin buckle. Altogether, this G.F.J. feels like a study in control and material mastery—quietly complex, highly technical, and exceptionally rare.\u003cbr\u003e\u003c\/p\u003e","brand":"Zenith","offers":[{"title":"Default Title","offer_id":48673935589626,"sku":null,"price":83400.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0520\/9554\/9621\/files\/1_839ed383-a874-4df6-93e7-877b383ec8a4.png?v=1776858127","url":"https:\/\/www.moyerfinejewelers.com\/products\/zenith-g-f-j-calibre-135-98-1865-0135-21-c205","provider":"Moyer Fine Jewelers","version":"1.0","type":"link"}
