Nivada Grenchen Aquamar Blue 32074A20

The Aquamar collection from Nivada Grenchen represents the modern revival of a lesser-known yet highly charismatic 1960s dive watch. Rooted in the celebrated Antarctic family, each Aquamar model combines vintage charm with professional-grade technical features , making it an extremely versatile and collectible timepiece.

True to its original proportions, the Aquamar features a 38 mm stainless steel case , double-domed sapphire crystal , and water resistance to 200 meters , making it perfect for both underwater adventures and everyday wear. Its bidirectional ceramic bezel and sandwich dial offer depth, readability, and a distinctive character.

A distinctive feature of the collection is the two-tone "roulette" date disc , which adds a playful, collector-favorite touch to an otherwise functionally oriented design. But what truly sets the Aquamar apart is its innovative variable luminescence system : the date disc is infused with two different shades of Super-LumiNova, white and vintage beige . As the date changes, so does the luminescence, giving the watch a look that subtly alternates between a clean, modern look and a warm, aged aesthetic. This ingenious feature transforms the Aquamar into a dynamic visual experience that evolves daily on the wrist.
