Just tested, dry, up to 5 Bar, no leaks over 10 mins, cylinder rated at 125psi, which is just over 8 bar. Not sure if to go any higher than 5 Bar.  :unsure:

 

Rob, what's the max pressure you have taken yours to?

I haven't gone higher than 5 Bar with mine.

 

5 Bar is 40 metres depth. So I think that will be adequate for most services. 50 metres plus I feel you would want it tested professionally, if your diving to those depths.

I feel confident that this tester will ensure the watch is OK for swimming but if you need checking for more advanced stuff like snorkelling or proper diving you should do it with a real tester.

Just remember that 40 or 50M depth does not necessarily correspond to the actual diving a watch can handle in the real world.

Having said that, you are absolutely correct - if a professional diver needs a suitable watch tested, he/she should send the watch to someone with the correct equipment, and insurance as their lives will depend on it.

 

The calyso, bergeon and indeed this solution are to be used to detect leaks, but in my opinion, they should not be used to determine if a watch can be guaranteed for use under water.

 

For the classifications and recommended use for each classification see my post here: http://www.watchrepairtalk.com/topic/1803-waterproof-testers/

Rob, I recommend you only put just enough water to cover the watch and not much more, I feel the chamber has too much.

 

The picture is deceiving, the blue top part is filled with a porous material that the watch can rest on but also allows water to enter. So when turned over the water just covers the watch.

Very good! Thanks for sharing.

 

Have you tested it on a watch with a known problem? May be useful to experiment by putting a kink in a gasket to simulate a failure, just for science :)

Yes Mark. This watch failed on first test when I received it. After I serviced, refurbed, greased and sealed, no problems. 

 

Very pleased with it.

This is great, I've been trying to justify the cost to purchase a good tester for a while (I wouldn't trust the cheap ones on eBay with my face close under pressure). Ill definitely be making myself one of these.

Nice one

      Stem removal after fitting hands

      By Neverenoughwatches · Posted

      So leave off the seconds. Stand the movement on its edge, its the dial edge that rests on the pad ( either rubber or cork , something that wont slip ). Use a finger of your left hand to hold the movement upright,  right hand presses the release and flicks out the stem. I do it this way so i can see what I'm under a microscope. But you could hold the movement between two fingers of your left hand, its the right that has to manipulate the stem out by pushing the release and flicking out the stem with  right ring finger nail. Sounds more complicated than it actually is. I guess you could fix a push pin to something solid, then all you need to do is push the release against the pin, leaving your right hand completely free to pull the stem out.

      Try putting everything back together and closing the back cover. I think one of the two springs has to contact the metal casing to ground the casing. So when you press the button, it will touch the contact on circuit board and close the circuit.

      Yes, the seconds hand is the longest and goes almost to the edge of the dial. I can’t quite picture it how you do it on the rubber pad

      A don't think so it leaked or damaged it because the watch itself works it just the buttons ain't working not connecting with the circuit board have taken more pictures of where the buttons makes contact with the circuit board.

      I think what peter means oh is once he has fitted the hands and  checked for  alignment if them and that they dont foul, how does he then hold the movement to remove the stem in order to case up. The dial cannot be laid on a cushion or in a movement holder as the hands will get damaged. This can be quite tricky for a beginner, what i do is  to stand the movement on edge on a rubber pad so it doesn't slip. Hold the top edge with one finger then my dominant hand uses 3 fingers to press the stem release and flick out the stem. See below peter, leave off the second hand as this is the longest and gets caught the most, then fit it once the stem is out. Alternatively place the movement in one of the cup style holders, i imagine this is what they are designed for. They only touch the very edge of the dial.
