Founded in 1962 in Geneva, Switzerland, Aquastar is known for its professional dive watches developed for marine research and underwater exploration. The Benthos collection represents the brand’s legacy of purpose-built underwater instruments, inspired by historic models from the 1970s.

The Aquastar Benthos Heritage II Limited Edition is a modern reinterpretation of the original Benthos, combining historic design cues with contemporary proportions. The watch features a 40 mm 904L stainless steel case paired with a semi-glossy black dial. High-density old radium Super-LumiNova, bold hands, and the distinctive dual-crown layout ensure excellent legibility and a recognisable dive-watch character. Powered by the Sellita SW200-1 automatic movement, it offers a 38-hour power reserve, a frequency of 28,800 vph, and functions including hours, minutes, seconds, a 60-minute unidirectional rotating bezel, and a manual helium escape valve at 4 o’clock. A flat sapphire crystal with triple anti-reflective coating protects the dial, while the ceramic bezel enhances its professional functionality. Water resistance is rated at 300 meters. The watch is fitted on a rubber Wolbrook strap. This Benthos Heritage II Limited Edition is in near mint condition and comes as a full set.
