Crown gasket on andrews 4th PO

[thorg12]

I am just wondering where the gasket is on the crown? is it inside the crown or is it at the base by the watch? When i unscrew mine i dont see a rubber gasket like the rolex's but i think i see something inside the crown. I did the hot water test and no bubbles but im goin on vacation and would like to swim with the watch. Any feedback would be appreciated.

There is a recessed o-ring in a groove just inside the opening of the case tube, and there is also a thick, flat rubber gasket inside the crown itself that seals against the end of the tube.
