Seems a bit of a journey. I have done this mod and also work in subsea engineering and do something similar on our vehicles. Fill all the air spaced with oil and compansate the oil (water pressure reacts against a bladder to equalise the oil to same pressure). If you have any air gaps basically messes it up. Also depends on the way they test it, can't test this type of watch in some watch testers such as the ones were you released pressure under watcher. Other problem is oil does expand so you do need to have something which will give to allow this exspansion or pop. Sorry for the long comment, short version it's not easy to test this mod without doing it in the true enviroment :) Great video mate :)
@@JohnBrown-mq3mn It would yes however if you dive this air compresses so you then get the water pressure acting more on the outside of the case. On kit we work on we use compensators which aid in this function :)
Check out Jody Musgrove in Sydney who bought some rudimentary kit for testing pressure and checked out the claims of Chinese watches. He's at Just One More Watch on UA-cam. Today I was looking at the U Boat Capsoil watches which have a dial bubble rather like a spirit level, as yours does now. I wouldn't know why though. Just for fun I thought that I would try to fill a watch myself so got a really cheap piece of junk and filled it with rapeseed oil. It worked out quite well except that the white dial went piss coloured. The oil smells of fish anyway, so it was no great loss. Next I think I might try it on the same model as yours using silicone oil. Mine has a black dial and orange numbers. I'm sorry that you were messed about. Good luck with your next attempt. And thanks for your previous video on this. 👍
If the test gets fine then your new technology is going to hurt the much hyped Sinn 1000m dive quartz watch sells at really high price even being a quartz movement.
@@BenDunlop Just to keep things simple, avoid unnecessary complications - KISS, as they say. Otherwise, they would be filling the inside of submarines w/ oil.
@@speedygonzales9993 that's fair. This wouldn't be done to my favorite watch. More like a DIY kit to try on a cheap quartz watch conversation starter on my wrist.
Some people would say why do this? You say why not do this. Bravo

Wouldn't the air bubble allow for expansion?

I think that the bubble could be a problem in the test. Send the watch for testing without any air inside. Thank for the video.
Any follow up on the accuracy?
Yeah I dig the just for the hell of it aspect.

Can it work on a Casio DBC 150 Watch
1000cst silicone oil? Is it good for watch ?

why? do you even scuba dive??
Heck of an adventure you're on with this. Curious what the third tester will say.
I see an air bubble...☹️
Did you get your money back? I would not Rock that shop. 🤣
Lol
It actually cost me money and they did nothing...
WatchChris 😡 I hate that.
I would avoid oil-filled watches.
Why?

@@BenDunlop I fully understand. Tks.
@Siebenstern Yes. Oil-filled watches are just 'uggh'. They make no sense to me.
