2023 markd the opening of the latest chapter in the last great story in dive watches, as venerable Swiss dive instrument maker Aquastar returns with a new Model 60 — a fully modernized tribute to the brand’s inaugural 1957 dive watch of the same name, which introduced a crucial safety measure for dive watches of that era: a friction ring in the rotating bezel to prevent accidental rotations. Devised and originally patented by Aquastar, this simple, but critical feature would later become a standard feature echoed by legions of dive watches in the years that followed.

The new Model 60 Greenwich continues Aquastar’s earliest traditions of capability, adventure and exploration, which began in earnest on January 23rd in 1960 when US Navy Lieutenant Don Walsh, wearing an original Model 60, and co-pilot Jacques Piccard, made a pioneering journey to the bottom of the Challenger Deep, aboard the bathyscaphe Trieste to a record-breaking depth of 10,916 meters (35,814 feet). Walsh’s Model 60 is recognized as Aquastar’s inaugural tool watch, and would set an early precedent for the then-nascent maker, as Aquastar’s innovative and ultra-reliable watches would quickly earn a reputation as the foremost timekeeping choice for mariners, professional divers, and ocean conservationists alike.

The evolution of the model 60

With applied markers, the luminosity of the indices has been improved dramatically and adding a genuine ETA 2824-2 to power the Model 60 makes it a great choice for movement aficionados.  Still  Thoughtfully sized in a 37mm stainless steel case the Model 60 is a somewhat unique reference in the Aquastar archive. In keeping with Aquastar’s modern traditions, the new Model 60 maintains a robust 200 meters of water resistance, and is powered by the legendary ETA 2824-2 Caliber. The Aquastar model 60 comes on a choice of straps and bracelets. A seatbelt NATO, a genuine or a beads of rice stainless steel bracelet.

“With every Aquastar release, we try to look at the product cycles introduced by the brand’s original founder, Frederic Robert, and look ahead to what he might still be producing, had the brand never been paused during the quartz crisis,” says Rick Marei, Aquastar’s modern helmsman. “We are proud to be both historians and custodians of this rich brand, using the new Model 60 to pay tribute to Aquastar’s influence and innovations in the world of undersea exploration,” he continues.
