Verifying a watch

Would you ever let someone (a watch maker) open your watch (to verify its authenticity when you are selling it) PRIOR to actually selling it? Can that damage your watch? Is that a stupid move to allow them to do that?

You're in NYC? Bring the watch to RSC. Tell them you'd like to get an estimate for standard service.

They will take your watch into the technician area. 15 minutes they'll come back out and either hand you a service estimate or tell you the watch has an issue with authenticity and/or originally. typically there's no in between. Easiest way to verify a watch.

No, it won't damage a watch for a watchmaker to open it up; why would you think that it could ?

I have sold watches to dealers that ask to look at the movement.
They would only open while I looked on.

Likely not, but improperly pressure testing a closed watch could be an issue I suppose?

Hi

I confess to having a low technical knowledge on watches in general but how do you know that the watch would pass a pressure test after an "ordinary" person has removed and then replaced the back plate on what was a perfectly good watch.

Regards

Mick

I'm in the same boat! That's why I state it as a question. My guess, is that it partially comes down to equipment. You either have the machine to test for it or you don't. The other part is just old fashion competence.

It's not that hard really, it's a gasket, if it is flat as a pancake or torn etc it's stuffed, if it's soft and spongy it's good. You then install it in the slot or caseback edge, depending on model. You then torque the case back, it's like changing a tap washer really, as long as you use correct tools, it is easy. If it was waterproof before it will be afterwards as long as the gaskets are ok. Cheers.

Allowing the buyers jeweler to open it, I'm not sure if they're an AD (rolex). Just curious what people think! I personally wouldn't feel comfortable unless I knew it was an AD, but want to see what the experts think as I am just a novice!

Great advice! Do they charge for that?

It doesn't matter who opens it, the only way to "know" if it will pass a pressure test is to test it.

But there isn't any magic there. It's an o-ring in a groove and with reasonable care that it stays there, the watch will be water-tight.
