Aquadive is proud to be the official watch supplier, and financial supporter, of the Lost Ships of Cortés Project, one of the most important archaeological expeditions of all time.


In 1519, the Spanish conquistador, Hérnan Cortés, came ashore and established the first European settlement in what would later become Mexico, the town of Villa Rica de la Vera Cruz. In an attempt to prevent mutiny and abandonment by his men, he ordered 10 of his ships scuttled offshore, a remarkable act of “all or nothing” commitment. The remains of those ships have never been found.

In 2018, a team of underwater archaeologists set out to locate the lost ships of Cortés, using methods both high tech and incredibly basic, from systematic sea bed profiling to digging through meters of sand and clay. Near the end of the first season of work, the team made a remarkable discovery: an intact anchor, buried under the sand. Analysis of the style and composition of the anchor determined its age and origins, squarely from the era when Cortés landed on Mexican shores. It was a tantalizing clue that made news and brought the team back in 2019 with renewed enthusiasm. 


The 2019 season saw the Lost Ships of Cortés Project back in Mexico, narrowing down their focus on clues on the ocean floor, probing and excavating for evidence of those missing shipwrecks. The search area has been narrowed and further clues have been found. As the season winds down, the team packs up and heads for home, already eyeing a return to these Mexican waters.

Aquadive has been a part of the Lost Ships of Cortés Project since the beginning, both as a sponsor and watch supplier. Team members have worn Aquadive watches daily, relying on them for timing crucial details from diver rotations to meal times. There could be no greater proving ground for a dive watch than this expedition, where daily exposure to sun, sand, and saltwater conspire to play havoc with equipment. We’re proud to say the Bathyscaphe 300, Bathyscaphe 100, and Bathyscaphe 100 GMT models on the teams’ wrists not only endured, but proved an invaluable tool for the project.


“My Bathyscaphe 300 has been on my wrist for the better part of eight years now, and it’s a crucial tool for my profession”, says Fritz Hanselmann, co-director of the Lost Ships of Cortés Project. “It’s got its dings and its dents and it’s got its character, but I wouldn’t change that because it helps me do what I do.”
