Hi A picture of the underside of the bezel and the front of the watch would be helpful in determining the problem. On some bezels there is a wavy flat spring that fits under the bezel and then the bezel snaps on , the spring prividing the tension for the bezel. There are others in which there is a small hole in the case with a spring and a bearing (a Biro ball is some time used as a replacement) which detents on the underside of the bezel. thanks -

Hi Gaus, slightly off topic but which model Commodoor is this? I'm looking for a Parrenin 171X movement for a project and there are a couple of different model Commodoor watches on ebay at the moment. -

Hi Birb. This actually came in a cheap watch repair kit. Its really a hand remover, i took out the center part that lowers on to the hands to steady them and reshaped the tips to grab the cannon pinion when it closes up. The plastic sides push down on the mainplate and the cannon pinion pops staight up and off. -
Hi all. With the Bergeron 4854 which as long as you don't buy it on eBay is not that expensive for a Bergeon tool (about £65 plus Vat in the UK) but is designed for pocket watch Cannon Pinions has anyone found a way to modify it to pull the smaller sizes found on wrist watches. Anyone found a way to replace the 4 jaw chuck with a smaller 5/6 jaw version. Thanks

Question
UhrTobi
Hello,
I'm new here since a views hours and there is already my first problem I'm not able to solve. I did my first practice on a Seiko 7S26C movement. It is from a watch of a verry good friend. He was verry unsatisfied with its performance and told me, that the watch goes some times to fast, other times to slow. A timegrapher analytics shows this, too. In the same orientation the watch fluctuates between ca. +25s/day and -30s/day within a view minutes without any disturbance from outside. It had got a verry low amplitude of about 156°. He gave it to me just to practice. But now I have a strong motivation to fix the problem. I dissassembled it following Marks verry helpfull videos on youtube, cleaned and lubricated it and put it together two times. It still works nevertheless
. And the amplitude is now sometimes over 200° but suddenly it goes back to 180°. I could regulated the beat error down to ca. 0.1ms and it goes to max. 0.6ms depending on orientation. But the amplitude is still not stable and the accuracy is still fluctuating. The hair spring looks good ans all bearings seems to be clean. And so I can't guess, what the problem is. I would be verry glad if someone could give me some assotiations how I could fix the problem.
Many thanks an best regards
Tobi

It was not my intention to imply that you were wasting peoples time. I was trying to participate in the diagnosis, nothing more. Mainspring lubrication appears to be one of the complicated and p

Lubrication is a problem in watch repair because watch repair has spanned a very long time. The technical sheets the books the bulletins whatever people look at have spanned a long time. People embrac

If you find a patern in fluctuations, you have spotted where the fault is likely to be.
