Answer:
The two men were Jacques Piccard and Don Walsh
Explanation:
On January 23, 1960, the US army reached the Mariana Trench. The Trieste bathyscaphe was manned by Jacques Piccard and Don Walsh and they went down at 10900 meters. None had descended to that area of the Pacific Ocean until 2012. On that expedition, Piccard put a Rolex watch in a conduit that could be flooded in the submarine to conduct an experiment.
