Watchmaking History

TRIESTE Deep Sea design is inspired by the minimalist style of the watches on board of the bathyscaphe TRIESTE. 

Accompanying Jacques Piccard and Lt. Don Walsh on their TRIESTE dive were three Swiss Made watch brands, ultimately tying watchmaking with deep-sea exploration to this day.

 Movado provided a chronometer to record the time, while Longines offered up two stopwatches, which were used inside the bathyscaphe’s pressure sphere to time the activation of the two ballast tanks.

The most difficult challenge, however, was given to Rolex, a watchmaker that has always been associated with exploration of the planet’s furthest frontiers. Attached to the exterior of the bathyscaphe TRIESTE, the experimental Rolex Deep Sea Special timepiece was used to demonstrate Rolex’s unprecedented achievement in their Oyster — the world’s first waterproof wristwatch, invented by the manufacture in 1926



Once at depth in the Challenger Deep, the Rolex Deep Sea Special triumphantly withstood the enormous water pressure that no submersible, let alone wristwatch, had experienced before. Following the completion of the expedition, Jacques Piccard sent a message to Rolex’s headquarters in Geneva stating, “Happy to announce your watch as precise at 11,000 metres down as on surface.”



Today, water resistance is a fundamental feature of well-designed timepieces, making them more reliable and ensuring constant wearability, while premier divers watches — which offer water resistance to 300 metres or 30 bar, as our collection does — are an essential part of the watch aficionado’s collection.
