Antarctic Erotic Tuxedo 38mm, Mens Watch

Built on the iconic Antarctic platform introduced in the 1950s, the Antarctic Erotic reinterprets one of Nivada Grenchen’s most emblematic designs through a bold yet subtle evolution.

At its core, it remains a true daily watch: a perfectly balanced 38mm stainless steel alternating polished and brushed finish, paired with timeless dial executions inspired by vintage Antarctic models. But beyond the dial lies its secret. Flip the watch and interact with it the animated caseback comes to life through the winding motion. A miniature mechanical automaton, engineered as an extension of the movement itself, transforms a simple gesture into a private, playful experience.

This hidden animation remains invisible to the outside world, reserved only for the wearer. This concept follows a long-standing watchmaking tradition of discreet complications from automata to hidden scenes designed not to be shown, but discovered. Inside, a modified hand-wound Soprod P054 movement powers both timekeeping and the animation.

The mechanism has been re-engineered so the winding action drives a cam system, translating motion into a vertical animation on the caseback, without compromising reliability or wearability. Beyond its mechanical ingenuity, the Antarctic Erotic carries meaning. Rooted in the Antarctic legacy, first tested during U.S. Navy Operation Deep Freeze (1955–1956) the penguin became a historic symbol of the collection. This watch reinterprets that emblem with a modern twist, while contributing to real-world impact.
