Aquastar Benthos Professional 42mm Black Dial Rubber Mens Automatic Watch BENTHOS-PRO

The Aquastar Benthos Professional takes its design cues from the Benthos 500, first introduced in 1970, reinterpreting the historic dive watch in a more compact 40mm format. Crafted from corrosion-resistant 904L stainless steel, the case measures 44mm from lug to lug and retains the collection's distinctive layout, with a signed crown positioned at 2 o'clock and a manual helium-release valve at 4 o'clock. Protected by a flat sapphire crystal with triple anti-reflective coating, the semi-gloss black dial features applied hour markers filled with high-density Super-LumiNova for improved visibility in darker conditions. Framing the dial is a unidirectional ceramic bezel with 120 clicks and elapsed-time markings.

Swiss Automatic Movement

Powering the Benthos Professional is the Swiss-made Sellita SW200-1 automatic movement, driving the hour, minute and central seconds hands. Combined with a robust case construction and water resistance of 300 metres (1,000 feet), the movement supports the watch's professional diving capabilities. The manual helium-release valve further reinforces its connection to the underwater world.

ISOfrane® Rubber Strap

The Benthos Professional is fitted with a black genuine ISOfrane® rubber strap, a design long associated with professional diving watches. Combining flexibility and durability, the strap complements the watch's purpose-built character while remaining comfortable on the wrist. Bringing together Aquastar's diving heritage and the spirit of the original Benthos 500, the Benthos Professional balances vintage inspiration with modern watchmaking.

Limited to 500 pieces, the Benthos Professional offers collectors and dive-watch enthusiasts an opportunity to own a modern interpretation of one of Aquastar's most recognisable designs.
