Concern when buying a Sub or SD (help Pls)

[Rsvrider]

I'm in the market to replace my lost Sub. More often than not ( highly appreciated) the seller of the watch shows the movement in a pic to authenticate the piece. My question is: once I decide on one -and receive the watch- do I need to take it itno service to pressure test it? My original Sub was bought directly fom an AD so I never had reservations when taking it scuba, my concern is that I may buy a second hand watch that may take water in or -worse- pop open when coming up from a dive! Lost one to the sea already, don't want this to become a "tradition".

As many will tell you, buy the seller first. In doing so authenticity will be ensured. I think it would be wise to have any preowned watch pressure tested prior to diving with it. The test is simple, quick and very inexpensive if not free.

If you have any doubt you might as well have it tested.

Some dealers will do it free but even if they do charge you it was only £30 the last time i had mine done.

That's peanuts to put your mind at ease.

Well with any watch if not bought new it would be wise to have a pressure check done,and if used regularly for diving checked once or twice a year if used underwater a lot..Today most high street watchmakers could test to 200m plus if watch passes that test it will be fine for scuba.

I think it always best to take any pre-owned watch into your nearest AD and have them check it out. Have them check to ensure it is authentic and verify there are no issues.

Even if you buy it new it's always best to have it pressure checked at least once or twice a year if you plan on taking it in water and verify the seals are in tact and in good working order.

Heck yes. All you've seen is a picture of a movement. If it's that much a concern open it at your watchmakers and have him pressure check it.

A picture is just a picture, if you have any questions about a seller, move on. There are waaay to many watches and great sellers out there to lose a moment of sleep due to doubt

If you are buying a pre-owned sub and are going to dive with it I would pressure test it at a minimum. Since it is a part of your safety equipment, unless you know with certainty that it was recently serviced (meaning all seals replaced), I would have it serviced, specify that the seals are replaced and ask for the pressure test results. It's one thing to buy a used watch to wear, it's another thing when it's part of your critical gear.

On the flip side, as a seller,
I have been asked to provide movement pics when selling a watch, I have a set of case openers, but sometimes the cover is just too tight to get it off. Added to that, if I know the watch to be be serviced and waterproof, why would I want to remove the back cover...
