Love it!
The Daytona looks like its crown is unscrewed
I love this! A total of 5 watches tested, 4 passed. The XF SD43 showed some leaks in the decompression stage, the rest were awesome!
Unknown Factory Tudor Pelagos (easiest to pass, no bubbles or anything)
Green Factory Cermit, this one was already waterproofed by the former owner, I did it again since I opened it to regulate it.
VSF GMT PO, at first I thought it had a leak, but after a few runs, it was all air trapped in the bezel and fake HE valve.
ZZF Junior 116610LN. This one is another champ, only thing was the pearl fell off during the test, now is back on with gorilla glue.
The loser of the 5, the XF SD43. Bubbles from the crown and caseback. Will not be using this one in the pool. Might send it to someone to just double check it, it was a stream of bubbles towards the end of the decompression.
Also fixed the bezel alignment on the Pelagos.

Yeah it was haha. Still, no water ingress which is nice!
Bubbles under the bezel really make you worry when your testing. For what its worth, the one watch i have that leaks from the crystal gasket (no matter how much magic seal i throw at it) is really quite obvious with the shear amount of bubbles that come out. The odd bubble or two is normally just trapped air. At least none of the watches ive taken that approach with and then swum with have leaked.
I guess you have tried greasing all the seals on the sea dweller? Could always try replacing the gaskets if the problem continues. Should be able to see any damage to them under a scope though.
That's what I have always wondered when I test mine. The stray's are what make me wonder even though I'm pretty sure that watch is tight in all areas.
I like to test just before vacations also for snorkeling and/or light water activity. The watches tested with random bubbles have never had problems during regular use, but there's always that nagging thought at the back of your head...
So the question is how many bubbles does it take to raise the red flag???
I would say a somewhat constant stream of bubbles, I also learned to move the watch a little bit while under water, that releases a lot of the air in the outer areas. If it's a bubble or two, I don't think of it as a big deal.
How are you guys handling crowns that don’t screw in when water testing? Also, why are the movements being left in the watch when testing?

Just shorten the stem a bit if its not tightening down? I usually do a double test, first pressurise to 6 bar, leave it 5 minutes, then dump the pressure. If the crystal doesnt blow out (this has happened to me more times than i would like) I repeat and put it under water before releasing. If its pissing out air you tend to remove it from the water pretty sharpish. Plus im lazy and most of my watches have 2836’s. Not saying the keyless will always get screwed up, but it really annoys me when you get the hands bang on 12 for the date, go to put the stem in then have to take it all apart and reset it.
Thanks for the explanation! From another members post about his journey on his first movement service, I finally decided to pick up watchmaking as a hobby. In the past, I’ve always paid someone else to do it; however, I can’t seem to get a hold of any watchmakers. I’m just going to go all in and work my way up to modified 7750 movements.
Another smooth pass from this BPSD. I know these easily hold up to 100 meters, so I was not surprised.
VR3135 swap day for the BP SD and the JF LV.
The BP's SA started acting bad almost immediately. The JF SH was doing good, just the date font is too thick. Got the VR3135's from a US seller on eBay.
Both running with great amplitude and very minimal adjusting was needed.

Didn’t take pictures BUT, just tested my new Helenarou 6538 AND my JF LV to 5atm. Both impressed with how easy both passed.

Had to source a new seconds hand as the original JF’s second hand post got stuck to the old 3135 movement.
Now it’s back to it’s glory.
There is something about LV that its just beautiful. Everytime i see one i tell myself i need to have one.
Especially with the apple green inserts :dribble:
VSF Cermit passes the 5ATM test. I did notice very, very tiny (honestly, miniscule) bubbles but these came from under the bezel. Crown, crystal, and caseback showed nothing.
Today on the oversized Ikea table I call my “bench”, V1 TC YM, small regulation and w/r test. Passed both nicely.

You really have some balls using tester with movement inside haha, it's all good until one day it's not

I don’t put it in the water immediately. I do a two part test.
I pressurize it for three minutes without submerging and let the air escape. If the crystal pops at that stage, then it’s obvious a no go.
If it doesn’t, then I repeat the process and then submerge.
Hasn’t failed me yet.
Even Bergeon’s instructions show the watch with the movement installed lol
