{"product_id":"nivada-grenchen-antarctic-erotic-stem-winding-320693m16","title":"Nivada Grenchen Antarctic Erotic Stem Winding – 320693M16","description":"The Nivada Grenchen Antarctic Erotic Brown (320693M16) combines vintage-inspired styling with an imaginative mechanical complication rooted in the brand’s rich heritage. Its warm brown matte dial, accented by applied indexes filled with beige Super-LumiNova, draws inspiration from mid-century field and pilot watches, creating a distinctive vintage character with a warm glow in low-light conditions. The 38mm case is crafted from 316L stainless steel with alternating polished and brushed finishes, preserving the classic proportions of the original Antarctic collection from the 1950s. A double-domed sapphire crystal protects the dial, while the open case back features a flat sapphire window that reveals the watch’s most intriguing detail. When the signed screw-down crown is wound, the modified hand-wound Soprod P054 Caliber activates a specially engineered cam system that brings a mechanical penguin animation to life. The animation moves only while winding, offering a fascinating mechanical display inspired by Nivada Grenchen’s patented penguin emblem from 1965. Measuring 12.45mm thick with a 45mm lug-to-lug distance, the watch offers comfortable everyday proportions and water resistance up to 100 meters. Completed with a choice of leather strap or stainless steel bracelet, the Antarctic Erotic Brown is a remarkable blend of mid-century design, Swiss craftsmanship, and playful mechanical ingenuity.","brand":"Nivada Grenchen","offers":[{"title":"Default Title","offer_id":68030162993454,"sku":"NIV-320693M16","price":1569.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0722\/0550\/0718\/files\/320693M16-1.jpg?v=1794662847","url":"https:\/\/littletreasury.com\/products\/nivada-grenchen-antarctic-erotic-stem-winding-320693m16","provider":"Little Treasury Jewelers","version":"1.0","type":"link"}
