The Nivada Grenchen 320691M16, part of the Antarctic Erotic collection, is a distinctive reinterpretation of the brand’s historic Antarctic line combining classic mid-century design with a discreet and unconventional twist. Rooted in the legacy of the original Antarctic watches from the 1950s, this model preserves the clean, functional aesthetic of a traditional tool watch while introducing a playful mechanical element hidden from view.
Housed in a 38mm stainless steel case, the watch maintains the balanced proportions that define the Antarctic collection. The case features a combination of polished and brushed finishes, offering a refined yet durable construction suited for everyday wear. With a thickness of approximately 12.45mm and a lug-to-lug distance of 45mm, it delivers a comfortable wrist presence while staying true to vintage sizing.
The eggshell dial presents a timeless and understated look, reinforcing the watch’s classic character. Designed with clarity in mind, it features a clean layout with well-defined indexes and hands, ensuring excellent legibility in daily use. This restrained dial design reflects the utilitarian roots of the Antarctic line appearing simple and traditional at first glance.
Beneath this classic exterior lies the defining feature of the Antarctic Erotic collection: an animated caseback. Visible through a transparent sapphire window, a mechanical scene comes to life when the watch is wound, powered by a specially modified hand-wound Soprod P054 movement. This innovative mechanism transforms the act of winding into an interactive experience, adding a private and unexpected dimension to the watch.
Despite its playful complication, the watch remains grounded in practicality. It offers 100 metres of water resistance and is built with robust materials, ensuring it performs reliably as an everyday timepiece. A single-curve sapphire crystal protects the dial, maintaining durability while preserving a subtle vintage profile.
The Nivada Grenchen 320691M16 stands as a unique blend of heritage and creativity combining the timeless appeal of a classic Antarctic watch with a hidden mechanical feature that adds personality and intrigue. It is a timepiece that respects tradition while embracing individuality, offering something both familiar and unexpectedly playful for modern collectors.

NIVADA GRENCHEN
ANTARCTIC EROTIC
Inspired by traditional erotic watches, the Antarctic Erotic, available in six dials including this brown, embraces hidden scenes and playful automata, designed to be discovered, not displayed.
THE PENGUIN
PATENTED SINCE 1965
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, brought to life here on a brown dial that echoes the patina of original 1960s Antarctic watches.
WRAPPED FOR THE ANTARCTIC
PRESENTATION BOX
Each Antarctic Erotic comes presented in a custom faux-fur watch roll inspired by the collection’s polar heritage. Soft, protective, and unexpected, it extends the spirit of the watch beyond the wrist complete with a matching travel pouch for storage on the move.
