First, what kills people when jumping from a bridge is decelaration (negative acceleration), not pressure.
A body (or something with the same Cx - aerodinamic coefficient) would hit water at a speed inferior to 300 km/h (190 mph) whitch is the speed of a freejump. At that speed, dynamic pressure would be equivalent to 83.3 meters of water = 8.33 atm (300,000/3600 = 83.3 m/s).
Your 10ATM rated watch would not leak but you wouldn't survive. Of course, the decelaration would maybe kill the movement but water wouldn't enter.
Regs.
