60 years ago, January 23, 1960 US navy Lt Don Walsh and Swiss oceanographer Jacques Piccard, son of engineer/aeronaut Auguste Piccard, succeeded to dive to the Challenger Deep the deepest point on Earth’s seabed in the Mariana trench in the Pacific Ocean. Their bathyscaphe “Trieste” touched the ocean floor at a depth of  10911 meters but had a cracked window. Trieste’s descent took five hours and the two men spent barely twenty minutes on the ocean floor before undertaking the three hours 15 minutes ascent to the surface. Remarkably, Jacques Piccard had attached a Rolex dive watch, Deep Sea Special number 3, at the outside rails of the Bathyscaphe and this Rolex watch worked perfectly at all times. Photo shows Jacques Piccard in 1953 during their prototype tests near the harbor of Trieste, northeastern Italy. The adventure is described in the book “Seven Miles Down” ...

La ilustración muestra al hipotético batiscafo Al Andalus Explorer diseñado y construido por la Junta de Andalucía en España. Dispone de un pequeño robot (ROV) filoguiado para adentrarse en espacios pequeños. Para su comunicación permanente con el buque de superficie, aloja tres boyas repetidoras con un alcance de 1.800 metros cada una que le permiten descender a 5.400 metros sin perder el enlace con la superficie.

After a 5 hours descent, their blimp-shaped bathyscaphe “Trieste” touched the ocean floor at a depth of  10911 meters but had a cracked window. It took 3 hours 15 minutes to ascent to the surface. Remarkably, Jacques Piccard had attached a Rolex dive watch, Deep Sea Special number 3, at the outside rails of the Bathyscaphe and this Rolex watch worked perfectly at all times. The Deep Sea Special was a special watch and Rolex only made six of these. The maritime adventure is described in the book “Seven Miles Down”. Photo shows Jacques Piccard with his wife and two-years old son Bertrand in 1960. Note both Piccard and his wife wore a Rolex wristwatch. (Photo: UPI)
