OK - I did a search and really couldn't find much on this (I'm reposting this from dive watch sub-forum - I guess only new iron flies over there). Has anyone here ever bought (or been given/willed) an older (pre 1980's & earlier) dive watch and had it serviced and gaskets replaced & pressure tested? Is it even really possible to be confident in using a pre- 1980's and earlier dive watch in the water that's been serviced? I know technology has improved a lot over the years and many of the older dive watches I've come across don't have very high ratings engraved on the back. I really like the look of some of those old watches (esp. some of the funky cushion cased ones) and would like to maybe get one and have it restored, but I would want to be able to use it as such and not just a 'dry only' use watch.
