Nivada Grenchen Antarctic Erotic

Love At-20°C
At the heart of the erotic watch: a hand-wound Soprod P054, adapted to drive the animated caseback mechanism while preserving daily-wear reliability and a clean display on the front.
Six DIALS.
A Statement Caseback.
Six distinct personalities. One shared secret on the back. Choose your shade the penguins remain unchanged.


THE PENGUIN
Patented Since 1965
First introduced on our vintage models inspired by mid-century polar expeditions, the penguin engraving watch became a quiet signature of the collection.
More than a symbol, the penguin is part of Nivada Grenchen’s heritage. Officially registered as a patent in 1965, this emblem traces back to the Antarctic collection’s roots in the age of polar exploration.
Reinterpreted here from the original archival patent, it connects the Antarctic Erotic to a genuine piece of the brand’s history where vintage inspiration, playful character, and watchmaking legacy meet.

ANTARCTIC EROTIC
ANIMATED CASEBACK
Conceived by “Dr. Coldwater,” the animated caseback complication transforms the simple act of winding into a hidden mechanical spectacle. Entirely revealed on the reverse side of the watch, this private animation is driven by motion, engineering, and a touch of irreverence. In this video, discover the assembly of the complication and the mechanical ingenuity behind a mechanism designed as a discreet surprise where playful storytelling meets serious watchmaking.
Inspired by traditional erotic watches, the Antarctic Erotic embraces hidden scenes and playful automata, designed to be discovered, not displayed.
