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?

      Epilame / Fixodrop

      By Klassiker · Posted

      I agree with @JohnR725. Oil on an epilamed surface is essentially the same as water on a waxed surface. The same physical properties are at work (surface tension vs. adhesion).

      Without Our Forum

      By Waggy · Posted

      I think we all get a lot out of this group, and it has been pivotal in my development by the sharing of knowledge, experience and learning from more seasoned experts such as @JohnR725 and others (you know who you are!) as well as fellow novices. I think that having a backup communication plan in reserve so that if there is a future problem just makes good sense. I don't think anyone is trying to undermine the forum, but if something unthinkable happens, like the Ranfft website for example, then it would be good if those who are willing can still keep in contact. Speaking personally, and I know I risk a charge of heresy, it would be good if Mark could be a little more visible in this forum, and maybe give any insight from time to time on the future/progress of forum and instructional videos etc. even if its just to confirm the status quo. I appreciate he is a busy man with a full time job, but so are most of the rest of us and to post a few lines every now and then shouldn't be too much to ask to reassure the restless villagers. Best outcome for me would be a message saying something along the lines of: "Hi guys, all good, no planned changes... enjoy the forum, will message again next month!" Just my two cents.

      Omega cal. 565 - low amplitude

      By Endeavor · Posted

      A nice looking watch !! Did you try 9010, instead of the 9415, on the pallet jewels / escape wheel? And if you did, did you notice a difference?

      By Waggy · Posted

      Knocked out another 404 last night...when you are in the zone! This watch was a non-runner which I picked up as part of a lot of 8 watches, so works out to be $3.12 per watch. Before:   And the finished watch, new crown and stem and the crystal was cracked so was replaced. I also replaced the mainspring as the original was the old steel type spiral and very 'set' - all else is original: The Movement was a AS 1686, but in reading around a little the ACCRO watch company were sued for their use of the five point crown on their Jacques Pere range as it resembled Rolex, see below: ACCRO then reverted to just ACCRO on their watches - I have done some sniffing around the internet and haven't seen another example of ACCRO and the crown together on a dial so maybe I have something unusual, or maybe I was looking in the wrong places 🙂.

      Pocket watch escape wh

      By Bonefixer · Posted

      This watch was damaged when I got it. I didn't break the escape wheel pivot, and I bodged a fix with epoxy to see if I could get it running. I'm not yet ready to get into lathe work, or shellacking jewels, and may never be. But I'm learning plenty with each watch I tackle.
