Pressure Testing

Post by magicman »

Hello there.

I've just enquired at a local watch service center, and to pressure test my Octon dive watch will be around £35.

Is that a decent price ? and do you get yours done regularly ?

Just done 5 mins research, and it seems if you get your watch wet. It's recommended that you get it tested anually.

I’ve read that too, Steve, though I suspect it might be honoured more in the breach than in the observance by most of us. I have had my Meistersinger about 14 months and if I take it on holiday in September I’ll probably just make sure the crown is screwed in properly and trust it. Actually, I almost always take watches off when swimming these days.

That sounds expensive, the last time I had one done cost €10 at the local watchmaker, only a 10bar test though more than enough for most purposes.

Just a thought: if you plan on testing regularly you can buy cheapo wet pressure testers (the sort that pressurise the watch case so that you can immerse it and see if bubbles escape) on ebay for something like £100 - though you'd have to factor in import charges as they probably ship out of China. At £35 a pop, I'd be tempted to go the DIY route.

^^^ Thanks, I've got another repairer to visit tomorrow, so I'll get a price from him.

I've never been asked if I required this testing, whenever I've had a battery change, so if it is a cheap service, I'm not sure why they wouldn't offer it. After all, they are checking their own work is done correctly.

I'm not sure I'll be removing, any more casebacks, had a problem getting a press fit one back on my wife's Tissot.

I suppose it might be because of the potential cost of a catastrophic failure. There's also the cost of removing the movement to test the empty case if you are doing wet tests (offhand I'm not sure how the crown gaskets seal without a watch inside, but maybe the crown will seal without it being attached to a movement)

Anyway, here's an interesting look and learn review of what's involved by Marc at Long Island Watches, that I found. Worth watching although it's not a short video. It discusses 3 different systems, one dry and two wet.

My link was incorrect. @Lavaine below has very kindly fixed it for me. :D

Thanks for that. I was trying to copy the link on my phone which I find hard enough anyway. I must have had that trailer instead. I didn't check it, I just assumed I had the right link.

You would have thought, after 12 plus years on a watch forum, I would have all this knowledge. And not even have to enquire on here.
I should be answering questions not asking them.

i guess it depends upon what you're testing. i might be more likely to either "wing it" or go cheap on a $300 watch. but a $4000 watch? i want that tested properly and $35 doesn't seem that bad for the peace of mind.

This is the best video I have found that shows all of the different equipment used to pressure test a watch. It is very in-depth but worth the time IMO.

Current CW = C65 Trident Vintage GMT, C65 Dartmouth, C60 Trident Ombré COSC LE, C65 Super Compressor

In Review:

2 More CW's on the short list! (This is pretty much a lie - I have at least 17 CW Tabs open at the moment!)
