Pressure test, O-Ring replacement on Long Island?

[Wooddog44]

Was just on the thread about "new" service intervals and now with water activities coming up (if the sun ever comes out again in the Northeast...) I'm stressing a bit over the watertightness of my Sub.

Was planning to send it for service later this summer/early fall (last done in July of '08) but if there is a reliable "walk-in" watchmaker in eastern Long Island that does the pressure test/ring replacement would take it there now, anyone have info on that?

Thanks!
