Aquastar Benthos 500 II 42mm Limited Edition Black Dial Rubber Mens Automatic Watch BENTHOS-500

The Aquastar Benthos 500 II Founder’s Edition marks the return of one of the brand's most sought-after dive watches. Faithful to the dimensions and aesthetics of the original Benthos 500 introduced in 1970, the watch is housed in a 42mm case crafted from 316L stainless steel, measuring 47mm from lug to lug with a reduced height of 15.4mm. The distinctive layout retains the chronograph pusher at 2 o'clock and the crown at 4 o'clock, while the semi-gloss black dial sits beneath a flat sapphire crystal with triple anti-reflective coating. Applied hour markers filled with high-density Super-LumiNova improve visibility in darker conditions, and the unidirectional ceramic bezel features luminous markings for elapsed-time tracking.

Exclusive Centre-Mounted Chronograph

At the heart of the Benthos 500 II Founder’s Edition is the Aquastar Calibre 1MPS, a Swiss-made top-grade movement developed in collaboration with La Joux-Perret. Created exclusively for Aquastar, the calibre revives the centre-mounted 60-minute chronograph display that made the original Benthos a standout among professional dive watches. Alongside the hour, minute and seconds hands, the movement powers the central chronograph counter and delivers a power reserve of approximately 60 hours. Combined with water resistance of up to 200 metres (660 feet), the watch continues Aquastar's tradition of purpose-built underwater instruments.

ISOfrane® Rubber Strap

The Benthos 500 II Founder’s Edition is fitted with a genuine 22mm ISOfrane® rubber strap, a design closely associated with professional diving watches. Combining durability and flexibility, the strap complements the robust character of the case while remaining comfortable on the wrist.

Limited to 300 pieces worldwide, the Founder’s Edition represents Aquastar's most prestigious modern interpretation of the Benthos chronograph.
