“Reality is different from simulation” explains Jerome Lambert, Jaeger-LeCoultre ultra dynamic CEO. He has a point. Because while the dive watch market is littered with timepiece with 1000 meter, 2,500 meter and even 3,000 meter depth ratings all of these depth rating are achieved using simulation. Watches are placed into a small tank in which an artificially pressurized environment is slowly built up. The last mechanical watch ever tested at depth was in 1953 when a specially manufactured Rolex Submariner was fixed to the exterior of Professor Auguste Piccard’s bathyscaphe to a world record depth of 10335ft below the ocean surface. However it should be noted that this Submariner was far from a production diving watch and more a purpose built instrument to test water resistant technology. What is extraordinary is that in the over half century since this experiment no luxury Swiss manufacture has submerged any of their deep saturation dive watches to their 1000 meter or more depth rating. That is until Jaeger-LeCoultre took up the challenge on a brutally hot clear skied day in Maui.

The depht is not correct, it should be 35,798 ft (10,911 m).

Cool article!! More research into this brand and I might just switch camps!

Well, those may be the official tests, but I seem to recall someone posting a shot of his SD at 1220 metres strapped to an underwater robot, with the depth data superimposed on the video screen.

Besides, the historical data reported is incorrect. A Rolex 7205/0 was fitted to the Trieste and reached 35798 feet on 23 January 1960. The Trieste was piloted by Auguste Piccard's son Jacques.
