The deepest dive made by humans was at aprox 322 mts in 2014, guy had like 10 oxygen tanks hanging on him and it didn’t look very comfortable like a walk in the park.
There was another attempt for 370 mt but was fatal.
These watches are made to outlast everyone one of us but it is cool to know that if you could dive at 1000 - 3000 mts you would be covered knowing the diving time [emoji41]
