The Antarctic Erotic Salmon is a 38 mm Swiss hand-wound watch with a salmon sunray brushed dial, a subtle metallic finish and applied indexes in a high-contrast layout. From the front it reads as a vintage-inspired Antarctic. Turn it over and wind the crown: through the sapphire caseback, a penguin animation comes to life, driven by the same winding motion that powers the movement.
The penguin belongs to Nivada Grenchen's own history. The emblem was registered as a patent in 1965 and engraved on the casebacks of Antarctic models inspired by mid-century polar expeditions. This animated version, conceived by Dr. Coldwater, redraws it from the original archival patent, and the salmon tone echoes the patina of original 1960s Antarctic watches. GQ, Hypebeast and Monochrome covered the collection at its launch.
Inside, a modified Soprod P054 hand-wound movement uses an integrated cam system to drive the animation. No battery, no electronics: stop winding and the scene stops. The 316L steel case alternates shiny and brushed surfaces, measures 12.45 mm thick and 45 mm lug to lug, and is water resistant to 10 ATM. Five other dials complete the Antarctic Erotic collection, including the Antarctic Erotic Eggshell.

Built on a polar legacy
First engineered in the 1950s for daily precision timekeeping, this 38mm stainless steel watch descends from a collection issued during Operation Deep Freeze, the 1955–56 U.S. Navy expedition to Antarctica. Its proportions, its applied indices, its brushed-and-polished alternating case finish, all preserved from that era. A genuine vintage-inspired dress watch that wears equally well on a flat-link bracelet or a leather strap.
The secret complication
Flip the watch over. Begin winding. The sapphire caseback reveals a mechanical animation invisible from the front: a hand-painted penguin automaton, driven by a cam system integrated directly into the movement. The winding motion, the same action that powers the Soprod P054 hand-wound movement, simultaneously drives the animation. No battery. No electronics. Pure mechanical ingenuity, hidden on the reverse side of the watch where only the wearer ever sees it.
This tradition of private, discreet complications, automata and erotic scenes concealed in watch casebacks, dates to 18th-century Swiss horology. The design reinterprets that heritage with irreverence and craft.
Specifications that matter
The 38mm 316L stainless steel case is 12.45mm thick with a 45mm lug-to-lug span, proportions that suit both smaller and larger wrists. The screw-down crown ensures water resistance to 10 ATM / 100 metres. A double-domed sapphire crystal protects the salmon sunray brushed dial. The modified Soprod P054 manual winding movement powers both timekeeping and the animation via the same winding motion.
Nine strap options
Available on a beads-of-rice stainless steel bracelet, a flat-link bracelet, black or brown racing perforated leather, smooth black or brown leather, black or brown leather with white contrast stitching, and a black rubber tropic strap. Each configuration changes the character of the watch entirely, from vintage dress to sport-ready tool watch.
