Help with very minor service attempt question please

[paddy0d]

Hi,

I got given a watch about 35 years ago - I believe a relatively low cost mechanical watch. It's been working ok up till recently but has stopped keeping good time. I think it is jamming at points and a tap gets it moving again.

I'd love to give the watch to my kids in a working state. Where I live there are no watch repairers who will touch it, and I'm not at a stage where I can attempt a full teardown clean and rebuild either in terms of time, skill or tools . Mostly lack of skill though. Just wanted to check - it is a single jewel watch. If I wanted to lubricate that jewel, would it just be a case of lifting cover in the circled area and putting a small drop of lubricant in?

Many thanks and sorry for the silly question.

 

Also any info on the movement would be interesting, I could not find much online.

 

Thanks,

Patrick

did anyone explain why they didn't want to touch it?

one of the problems with mechanical watches are they need to be serviced approximately every five years. If you go beyond this time span their lubrication will start disintegrate or basically no longer work properly. If you go long enough you will eventually wear the watch out. If you have a watch that has 0 J or perhaps one jewel then the amount of things that wear out greatly increase. So if you have a watch for 35 years it's basically worn out. Attempting a little fresh oil here and there isn't really going to solve the problem.

Hi there- I'm sorry to hear you do not have a watchmaker in your area that will service your watch- I have the same problem...

...a little bit of information: the movement (mechanicals) in your watch are likely a variation of an Ebosa 86:

Unfortunately as you suggest this is an inexpensive, lower quality of mechanical movement and yes, a quick drop of oil never helps. This type is not well suited to repair, which is probably why your local watch repair shops won't service it.

...students sometimes work on these types of movements because they are inexpensive, so it is possible a dismantling, cleaning and lubrication could have it running again. Perhaps there is a hobbyist local to you that might be willing?

Sorry it isn't better news...

As RANFFT says, this is a Roskopf style design.  Very similar to the BFG866.  I have worked on several and found them relatively easy to service.  There are a few tricks!

Where are you located?
