{"product_id":"f77-black-opal","title":"F77 MKII BLACK OPAL - 100 YEARS - 38MM","description":"\u003cp\u003eCreated for Nivada Grenchen's 100th anniversary, the F77 MKII Black Opal gives the brand's 1970s-inspired integrated icon a new mineral expression. Black Opal combines a dark base with flashes of blue, green, red and violet that shift with the light, giving every dial a distinct play of colour. Because each dial is cut from natural stone, colour, pattern and texture vary from one watch to another, making every dial unique. Traditionally associated with depth and transformation.\u003c\/p\u003e\u003cp\u003eThe 38mm case is made from 316L stainless steel and retains the integrated silhouette that defines the F77. Inside, the Swiss La Joux-Perret G101 automatic movement beats at 4 Hz, uses 24 jewels and delivers a 68-hour power reserve. The calibre is visible through the sapphire exhibition caseback, while water resistance is rated to 10 ATM.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eEach natural stone dial is unique. Variations in colour, pattern and texture are inherent to the material, so the watch delivered may differ slightly from product images.\u003c\/em\u003e\u003c\/p\u003e","brand":"Nivada Grenchen","offers":[{"title":"BRACELET","offer_id":44166009585752,"sku":"68062A77","price":1790.0,"currency_code":"USD","in_stock":true},{"title":"CANVAS VELCRO STRAP","offer_id":44166009618520,"sku":"68062A77-BC","price":1590.0,"currency_code":"USD","in_stock":true},{"title":"BLACK RUBBER TROPIC","offer_id":44166009651288,"sku":"68062A77-DR","price":1590.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0279\/4592\/6744\/files\/F77-LJP-100-Years-MRK2-38mm-BlackOpal-front_80ca53ee-8dcd-434b-8396-f2a6bd631f97.png?v=1790005542","url":"https:\/\/nivadagrenchenofficial.com\/products\/f77-black-opal","provider":" Nivada Grenchen ","version":"1.0","type":"link"}
