Theviking 197 Posted August 3, 2019 I've been putting this together over the last few weeks. From parts picked up of eBay. Water filter housing ~£10. To hold the watch and high pressure air A screw plug ~£2. To block the air outlet Screw in Schrader valve ~£2. To attach a bike pump to insert the air Screw adaptor ~£3. To attach the valve to the housing PTFE tape/grease/araldite. To seal the gaps between the parts. It took a few tries to get the thing airtight, you could hear the air escaping and the pressure drop. Greased the watch seals and crown screw thread. Put it in the housing, pumped it to 6atm left it for 10 min, pressed the escape valve (on top of the housing) and placed the watch into a bowl of water. No bubbles come out of the housing and it's good for swimming. Share this post Link to post Share on other sites
BadApple 13,081 Posted August 3, 2019 Mmmm - after reading this I hunted in the kitchen and found something that resembled this. I tried it out on one of my watches and turned on the switch. You owe me an ARF Sea Dweller. Share this post Link to post Share on other sites

I'm no scientist. I'm also incredibly stupid. It's entirely possible/probable that I've totally misunderstood this. However if I've understood correctly, let's say the watch had a massive leak, a big hole effectually, would the air not equalise immediately upon being taken out of the chamber, and when you then put it in the water, the water would flood straight into the watch?

Yes, but the gap would have to be massive for it to de-pressurise the watch without it hissing as you take it out of the housing. You have to remember, all automatic watches are built so not to let dust in, less it gunks up the movement. It doesn't take much to make a watch IP 53 which you need to keep the movement dust free. Build at you own risk or just never wear your diver rep in the pool. Share this post Link to post Share on other sites

The housing is rated to 12 bar and with a 50% safety rating this could go up to 18, but pumping the bike pump past 6 bar is an arse, but 6 is fine for swimming to the bottom of the pool. Which reps did you actually buy instead of dropping £1k on a Bergeon 5555/10 ? Share this post Link to post Share on other sites
BenjaminButton 149 Posted August 3, 2019 I test all my watches by diving into a pond and swimming round in circles for a couple of kilometres. So far so good. Life’s way too short to give a damn about my man jewelleries ability to survive a dip. Share this post Link to post Share on other sites
forevernoob 0 Posted August 3, 2019 Wow, what an ingenious idea. Way to McGuyver it. I'm inspired to try the same! Share this post Link to post Share on other sites
Theviking 197 Posted August 3, 2019 You could also build a wire watch stand, place it in the housing half fill with water, pressurise, wait, tip the housing over, watch in water, de-pressurise. To mimic the Bergeon test. Share this post Link to post Share on other sites
