Aquastar unveils its most prestigious dive watch to date, built around a newly developed center-mounted 60-minute chronograph calibre exclusive to Aquastar

For over fifty years, the Aquastar Benthos chronograph has remained the paragon of capability and dive watch collectability — a rarity in watchmaking both for its unique design and functionality, and its actual rarity as surviving examples remain scarce and highly collectable. However, since the brand’s triumphant re-launch in 2020, the modern Aquastar catalogue has been without this revered, and sought-after vintage icon, but it’s not without good reason: there have been no modern center-mounted chronograph movements commercially available for watchmakers to utilize. So in collaboration with La Joux-Perret, Aquastar rebuilt this key functionality, exclusively for its debut in the Benthos 500 Founder’s Edition.
