Hi,

I have a problem with my Bergeon 5555 waterproof tester. It loses air pressure when is pumped up to about 2atm. Sometimes quicker than 2atm. The air escapes through the post which is used to hang the watch on. I marked it with the red circle on the photo. There are no other leaks but this one makes the tool almost useless.

Do you know any way of sealing this spot? Any lubricant or... anything? I would say there is a need of gasket replacement, but can I open this lid somehow? :)

From the underside, if you take the hook for the watch off (one screw) and the circlip, you can slide the rod out the top. There is, as I recall, a, O ring in the hole. It may be very hard and tricky to get out. In the meantime try some silicone grease and see if that helps.

 

Much more annoying on these is when they start to leak water around the base under pressure!

I couldn’t find the silicone nearby so I ordered it from a watchmaker’s supplier. Also ordered some replacement gaskets. I will take off the bottom part to get the rod out.
I will let you know if it all worked after the weekend :)

Ok, so this is how it ended:

I actually needed two gaskets to get rid of the leak. Here are the places where they should be installed. One of them was missing...

It was more difficult to place the new ones than getting out the old ones.

Here’s how the old one looked like, well worn:

New gaskets for this Bergeon bought from a famous wholesale shop:

I also put a new gasket on the post:

And as the last step, I put some silicone grease on the post. It moves a lot more difficult now and is more stiff. As a result, it keeps 3atm easily now!

Thanks for your advice!

Where did you get the gaskets?

      Regulating is too touchy

      By Birbdad · Posted

      I agree with hector it's probably the regulator curve, it almost always is on these movements. So i work on these movements a lot and iv'e managed to fairly consistently get them running at like 50 degrees more amplitude than that with deltas in the 3 range and on the wrist deviations of sub 1 second a day. They ALWAYS require work to get there though. The main thing is shaping the regulator curve and this is really finnicky and definitely something you practice on a movement you don't care about when you're new (I'm still new) but if the hairspring is flat and the coils are evenly spaced and the regulator curve is properly shaped and it's pretty wild how accurate these movements can get.  But, it does sound like your regulator curve maybe needs a bit of reshaping. You can easily mess up the watch learning to do this so warning if you don't want to live with your current results but I"m not an expert, it's just speculation but there's a pretty easy way to check.  This is a good video showing how to see if your terminal curve is properly shaped. Just make sure the regulator pins are open when you test this.   He takes off the balance wheel to shape it. I do it with the movement disassembled but the balance on the mainplate. I use a homemade tool from a sharpened dental pic to do the adjustments (Tiny tiny TINY adjustments) and i use the regulator pins themselves to sorta brace the spring against to bend it very tiny amounts and just keep checking it by moving the regulator arm down it till it stops moving the hairspring. Taking off the balance wheel over and over again is a good way to slip and destroy your hairspring and will make the process way slower. I try to avoid removing the balance wheel from the cock it on these movements due to how difficult it is to get the hairspring stud back into the balance cock. It's super easy to slip and twist your spring then you got way worse problems.  Since these are mass manufactured and unadjusted the regulator curve is NEVER perfect but once you learn how to reshape them it's pretty easy to do and you can get REALLY low deltas with really low positional error and pretty remarkable accuracy.  Definitely with it powered down and the balance on the movement with both balance jewels in place look across the spring to see if it's perfectly flat, then check the regulator curve how he does it in the video. I would bet money even if it's not your main issue the regulator curve is not ideal also.

      Thanks. Damn, first breakage. This picture of the movement is from the sale listing.

      So the stem is snapped and will need replacing but luckily there's enough left in the crown to unscrew without a problem. Will need to see photos of the movement to identify it.
