A unique design that is not subject to any stereotypes. This is how we could characterize Nivada Grenchen watches from the Antarctic collection. The models from the Antarctic reissue boast a high-quality Swiss movement, modern elements and a choice between several strap options.
At first glance, it's a classic Antarctic 38 mm. But just turn it around and the story changes. The Antarctic Erotic model hides a playful animated caseback that only reveals itself when you wind it. A serious mechanical watch with a discreet, slightly provocative detail based on watchmaking tradition.
Built on the iconic Antarctic platform introduced in the 1950s, the Antarctic Erotic reinterprets one of Nivada Grenchen 's most distinctive designs through a bold yet subtle evolution. At its core, it remains a true everyday watch: the perfectly balanced 38 mm stainless steel case combines polished and brushed surfaces and is complemented by a timeless dial design inspired by vintage Antarctic models.
Behind the dial, however, lies their secret. Flip the watch over and the animated dial comes to life with a winding motion as you interact with it. Designed as an extension of the movement itself, the miniature mechanical movement turns a simple gesture into a private, playful experience. This hidden animation remains invisible to the surroundings and is intended only for the wearer.
A modified hand-wound Soprod P054 calibre works inside, powering both the movement of the watch and the animation itself. The movement has been redesigned so that the winding motion activates a cam system that converts the rotational movement into a vertical animation on the dial, without sacrificing reliability or wearing comfort.
In addition to its mechanical sophistication, the Antarctic Erotic carries symbolic meaning. They continue the legacy of the Antarctic collection, which was tested during the US Navy's Operation Deep Freeze (1955-1956). At the time, the penguin became a historical symbol of the entire range - and this model interprets it in a modern spirit, while also contributing to a real impact beyond the world of watchmaking.
