The Aquamar collection is Nivada Grenchen's modern revival of a lesser-known but charismatic dive watch from the late 1960s. Rooted in the Antarctic family, each Aquamar model blends vintage charm with professional-grade technical features, making it a highly versatile and collectible timepiece. Faithful to its original proportions, the Aquamar features a 38 mm stainless steel case, double-domed sapphire crystal, and a 200-meter water resistance rating, making it perfectly suited for both diving adventures and everyday wear. Its bi-directional ceramic bezel and sandwich-style dial offer depth, legibility, and distinctive character. A signature feature of the collection is the bi-color roulette-style date disc, which brings a whimsical, collector-friendly touch to the otherwise tool-oriented design. But what truly sets the Aquamar apart is its innovative changing lume system: the date disc itself is infused with two different Super-LumiNova tones-white and vintage beige. As the date changes, so does the glow, giving the watch a subtly shifting appearance between a crisp modern look and a warm, aged aesthetic. This clever feature transforms the Aquamar into a dynamic visual experience that evolves daily on the wrist. The dials-available in Matte Blue, Black, and Grey-are paired with white and faux patina options Super-LumiNova indices, further echoing the charm of aged tritium found on vintage divers. Powering the watch is the SOPROD P024 automatic movement, offering reliable Swiss precision and a 38-hour power reserve. Completing the package is an engraved caseback featuring the emblematic Antarctic penguin-a symbol of the collection's enduring spirit and roots in exploration.
