Its gunmetal-coloured dial displays a natural crystalline pattern with applied titanium-coloured indexes and an open-heart aperture at six o’clock, exposing the moving balance wheel. The angular case is finished with a brushed and polished surface, while the octagonal bezel is secured by eight screws. Measuring 46.2mm from lug to lug and 11.60mm thick with the exhibition caseback, the watch combines mechanical detail with a lightweight titanium construction. Water resistance is rated at 100 metres.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMeteorite Dial and Exposed Balance Wheel\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe genuine meteorite dial features a sun-brushed gunmetal finish that highlights the material's naturally formed pattern. Applied titanium-coloured indexes mark the hours, accompanied by white Super-LumiNova dots around the dial. The matching hands contain white Super-LumiNova for visibility in low-light conditions, while white printing and the embossed Nivada Grenchen logo complete the display. At six o’clock, the open-heart aperture reveals the oscillating balance wheel, bringing the movement's operation directly into view. The absence of a date display preserves the focus on the meteorite surface and mechanical opening.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSoprod Automatic Movement and Exhibition Caseback\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe watch is powered by the Swiss Soprod M100BV automatic movement, operating at 28,800 vibrations per hour, or 4Hz. Its 25 jewels and 42-hour power reserve support the movement's operation, driving the central hour, minute and sweeping seconds hands. The visible balance wheel provides an immediate view of the mechanism through the dial, while the see-through flat sapphire caseback reveals the movement from the reverse. This dual-sided presentation highlights the bridges, gears and automatic winding mechanism without interrupting the dial's time display.\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 surfaces and polished detailing. Eight bezel screws reinforce the octagonal outline, while drilled lugs allow the strap to be changed. A double-domed sapphire crystal with anti-reflective coating protects the dial. Instead of the integrated titanium bracelet, this version is fitted with a black canvas Velcro strap measuring 22mm at the case and tapering to 16mm. The 46.2mm lug-to-lug measurement and 11.60mm thickness with the exhibition caseback maintain the proportions of the design, while 100-metre water resistance adds practical functionality.\u003c\/p\u003e","brand":"Nivada Grenchen","offers":[{"title":"Default Title","offer_id":55472458858837,"sku":"68052A77-BC","price":2315.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0951\/3720\/2517\/files\/image492293252.jpg?v=1792660680","url":"https:\/\/witchnition.com\/en-es\/products\/nivada-grenchen-f77-mk2-38mm-open-heart-meteorite-dial-titanium-canvas-mens-automatic-watch-68052a77-bc","provider":"WatchNation","version":"1.0","type":"link"}
