The Aquamar Diver ships 2-3 weeks after purchase.
Celebrating the brand’s legacy rooted in the legendary Antarctic expedition, the Nivada Grenchen Antarctic Diver Aquamar revives a classic 1960s dive aesthetic with modern engineering and unexpected flair. Offered in matte blue and matte black dial variants, each model showcases a vintage-style sandwich dial with dual-tone Super-LumiNova that shifts daily via a clever roulette-style calendar disc — toggling between crisp white and faux patina bronze glow.
Housed in a perfectly balanced 38 mm stainless steel case with a bi-directional black ceramic bezel, double-domed sapphire crystal, and depth rating of 200 m, the Aquamar combines vintage sizing with professional specs. Inside beats the Swiss Soprod P024 automatic movement (28,800 vph), offering hacking seconds, a 38-hour power reserve, and reliability fit for modern explorers.
More than a diver — the Aquamar is an evolving object of time. As you turn the date wheel, the luminous signature beneath each hour index changes, giving wearers two styles in one: from sharp modern crispness to vintage warmth, all within a single, tool-driven diver design.

Nivada Grenchen timepieces have been in the watchmaking industry since 1926, the year when Jacob Schneider first created it in Granges (Grenchen). In 1976, his son Max took over the business. In the United States of America (USA), the Croton Company distributed all Nivada Grenchen watches. The timepieces can have either the Nivada Grenchen or Croton signature, or both.
In 1930, Nivada Grenchen was one of the first companies to manufacture automatic watches. This led to the creation of Nivada Grenchen’s first waterproof automatic watch called the Antarctic in 1950. The watch was worn by the members of the American Navy’s Deep Freeze 1 during their expedition to the South Pole from 1955 to 1956.
