Its angular case combines vertically brushed and polished surfaces, complemented by an octagonal bezel secured by eight screws. The dial features an embossed carbon-pattern texture, applied titanium-coloured indexes and luminous hands, with an open-heart aperture at six o’clock revealing the movement’s balance wheel. Measuring 46.2mm from lug to lug and 11.60mm thick with the exhibition caseback, the watch offers a distinctive combination of textured detailing and mechanical display. Water resistance is rated at 100 metres.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBlack Tressed Dial and Exposed Balance Wheel\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe dial features an embossed carbon pattern with a sun-brushed finish, creating a layered texture across its black surface. Applied titanium-coloured indexes mark the hours, accompanied by white Super-LumiNova dots around the dial perimeter. The matching hands contain white Super-LumiNova for visibility in low-light conditions, while the embossed Nivada Grenchen logo and white printing provide contrast against the dark background. Positioned at six o’clock, the open-heart aperture exposes the oscillating balance wheel, bringing the movement’s operation into the main display. The absence of a date window maintains the focus on the patterned dial and mechanical opening.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSoprod Automatic Movement and Exhibition Caseback\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe F77 MK II is powered by the Swiss Soprod M100BV automatic movement, operating at 28,800 vibrations per hour, or 4Hz. It contains 25 jewels and provides a 42-hour power reserve, driving the central hour, minute and sweeping seconds hands. The balance wheel is visible through the open-heart aperture, while the see-through flat sapphire caseback reveals the movement from the reverse. This presentation highlights the watch’s mechanical construction from both sides without adding a date display to the dial.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eGrade 5 Titanium Case and Canvas Velcro Strap\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe 38mm case is crafted from Grade 5 titanium with vertically brushed and polished surfaces. Eight screws secure the octagonal bezel, while the drilled lugs allow the strap to be changed. A double-domed sapphire crystal with anti-reflective coating protects the dial. Unlike the integrated titanium bracelet version, the 68023A77-BC is fitted with a black canvas Velcro strap, measuring 22mm at the case and tapering to 16mm. The adjustable fastening provides an alternative to a traditional bracelet clasp, while the 46.2mm lug-to-lug measurement, 11.60mm thickness with the exhibition caseback and 100-metre water resistance complete the watch’s specifications.\u003c\/p\u003e","brand":"Nivada Grenchen","offers":[{"title":"Default Title","offer_id":55472560046421,"sku":"68023A77-BC","price":2097.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0951\/3720\/2517\/files\/image492293286.jpg?v=1792661041","url":"https:\/\/witchnition.com\/en-de\/products\/nivada-grenchen-f77-mk2-38mm-open-heart-black-tressed-dial-titanium-canvas-mens-automatic-watch-68023a77-bc","provider":"WatchNation","version":"1.0","type":"link"}
