Probably not with that gasket
But if sealed to original factory spec then yes, it should be good for a static pressure equivalent to a depth of 666ft of water.
However, even with new replacement gaskets (back and crown) and a new crystal, you may struggle get it to achieve original spec. It's a 54 year old and over time it's possible that the surface condition of the sealing surfaces of the back and case, the crystal seat, and the crown could have deteriorated, even if only very slightly, making the original spec difficult to realize. It all depends on how those surfaces have fared over the last half century.
You can really only make that judgement after a pressure test.
On the other hand, as a desk diver it's brilliant
