BUILT FOR DEPTH
OWN YOUR TIME BOLDLY
A reimagined icon from the depths of the 60s.
The Antarctic Diver Aquamar is back—with a twist.
THE OCEAN DOESN’T FOLLOW, IT FLOWS
The sea doesn’t wait. It pulses, shifts, breathes. Out there, you learn not to force it but to feel it.
Whether it’s surfing, diving, or simply moving through water, every decision is about rhythm. You don’t fight the current, you follow instinct. You react, adapt, commit. It’s not just a sport, it’s timing, control, and presence in its purest form.
The Aquamar collection is inspired by those who live with precision below the surface, in motion, and in control.
Born from the heritage of vintage dive watches, it carries the spirit of resistance, performance, and timeless design.
Each model is built to adapt: to water, to movement, to purpose.It’s more than a diving instrument, it’s an everyday essential for those who choose presence over noise.
CHANGING LUMINOVA
At first glance, you’ll notice the rotating bezel and retro charm. But the real surprise is hidden within the dial, a playful bi-color calendar disc, switching from luminova white to faux-patina beige like a game of roulette.
Can’t decide between creamy vintage or crisp white lume? You don’t have to.This is the watch that changes with your mood.
THE RETURN OF AN ICON REIMAGINED WITH A TWIST
At first glance, you’ll notice the rotating bezel and retro charm. But the real surprise is hidden within the dial, a playful bi-color calendar disc, switching from luminova white to faux-patina beige like a game of roulette.
Can’t decide between creamy vintage or crisp white lume? You don’t have to.This is the watch that changes with your mood.
Faithfully reissued in every detail, the AQUAMAR returns today with one playful twist: a calendar disc that looks like a roulette wheel. A subtle nod to retro charm and a bold stroke of originality.
Vintage-inspired and irresistibly stylish, the AQUAMAR doesn’t require a dive to be worn, it feels right at home on the wrist in any setting. With a choice of matte dials in jean blue, graphite black, or stone grey, it’s made to stand out.
VINTAGE MODELS
FEATURES
Faithful to the original, it features creamy latte faux-patina hands, a classic dial layout, and a bi-directional bezel with black ceramic insert.
The twist? A roulette-style luminova date disc that shifts from white to beige, replacing the traditional date window with a bold, two-tone display.
On the caseback, the engraved penguin signature ofthe Antarctic collection nods to its icy heritage.
The Nivada Grenchen Aquamar is a 38 mm Swiss automatic dive watch, water resistant to 20 ATM / 200 m. It revives a lesser-known Nivada Grenchen diver of the late 1960s, part of the Antarctic family, for anyone who wants a compact diver that also works as an everyday watch.
Its signature is the roulette-style date disc. The disc carries two different Super-LumiNova tones, so the glow shifts as the date changes.
