{"product_id":"nivada-grenchen-antarctic-erotic-matt-brown-beige-luminous","title":"Nivada Grenchen Antarctic Erotic Matt Brown Beige Luminous","description":"\u003cp\u003eThe Antarctic Erotic Brown is a 38mm Swiss hand-wound automatic watch with a warm brown matte dial, beige Super-LumiNova applied indexes, and a hidden animated caseback that activates only while winding. It is the most vintage-toned dial in the Antarctic Erotic collection, a brown dial with warm beige lume rooted in mid-century field and pilot watch aesthetics, on a 316L stainless steel case with alternating polished and brushed finishing.\u003c\/p\u003e\n\u003cp\u003eThe case measures 38mm across, 12.45mm thick, with a 45mm lug-to-lug distance. A double-domed sapphire crystal, screw-down crown, and 10 ATM water resistance complete a package built for daily wear without compromise.\u003c\/p\u003e\n\u003cp\u003eThe caseback is what sets it apart. Flip the watch and wind the crown: a modified Soprod P054 movement drives a cam system that translates the winding motion into a vertical mechanical animation, a private scene visible only to the wearer. No extra pushers, no mode-switching. The complication exists entirely in the act of winding, in the tradition of discreet automata and hidden erotic watches designed to be discovered, not displayed.\u003c\/p\u003e\n\u003cp\u003eThe penguin figure at the centre of the animation has been part of Nivada Grenchen's identity since 1965, officially patented as the emblem of the Antarctic collection; a line born from the U.S Navy polar expeditions in 1955–1956. The Antarctic Erotic reinterprets that heritage with irreverence and mechanical precision.\u003c\/p\u003e","brand":"Nivada Grenchen","offers":[{"title":"Default Title","offer_id":56765950034306,"sku":"NIV-320693M04","price":3087.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/1636\/7523\/files\/8cbc9b44-1c98-44f5-abf7-a4e904745d38.jpg?v=1784023561","url":"https:\/\/www.watchgecko.com\/en-au\/products\/nivada-grenchen-antarctic-erotic-matt-brown-beige-luminous","provider":"WatchGecko","version":"1.0","type":"link"}
