The Secret Is Finally Out

After weeks of teasing, strange clues, and a worldwide tour that left more questions than answers… it's finally time to reveal what all the noise was about.
playful mechanical twist on the iconic Antarctic 38mm. A watch that looks perfectly serious on the front… but hides a far more mischievous story on the back.

BUT FIRST THE STORY
BEHIND THE CASEBACK

Our caseback is part of our Antarctic legacy. First introduced on our vintage models inspired by mid-century polar expeditions, the penguin engraving became a quiet signature of the collection. Today, it remains a faithful nod to our history, linking each watch to the landscapes, symbols, and spirit of exploration that shaped our origins.

Love At
-40°C

Once upon a time, not the cute kind… two penguins crossed paths in Antarctica. It was cold. They weren't. What started as casual curiosity quickly turned into something far more intentional. No hesitation. Just perfectly synchronized movement.

And when they realized the world was watching? They didn't slow down. Now their little polar secret lives on your wrist.

Behind Every Scene,
There's Movement

At the heart of the 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.

The miniature automaton is connected to the winding system. The ratchet wheel has been re-machined into a cam profile, converting winding action into a vertical motion driving the penguin.

WE DIDN'T STOP AT THE WATCH.
WE ADOPTED A COLONY OF 20000 THE PENGUINS.

"What makes this collaboration meaningful is that it connects curiosity about Antarctica with real scientific monitoring happening on the ground. Every penguin colony we track helps scientists better understand how this extraordinary region is changing. Support from partners like Nivada Grenchen helps ensure that this long-term scientific record continues to grow and inform global conservation efforts."
