Hello watchfriends, I have a commodoor three start mechanical watch, with a Parrenin 171 movement. The watch runs nice until 23:17 hours. Than the minute and hour hand stop, but the second hand stays running. This problems doesn't occur at 11:17 hours. What could probably cause this problem. Thank you all in advance. With kind regards, Hans

Hallo Nucejoe, yes it has a date complication. Is it the date wheel dat stops the motiontrain you think?

Setting the time by hand works fine. Setting the time changes the date at 24:00 hours is oké to. 

I think that I have found the problem. I removed the dayjumperspring and now it runs. Now I have to find out what the problem is with the jumper/spring. Thnx for thinking along.

Hi Gaus

 Yes I think its the load added by date jumper at hrs 23rd that makes canon pinion slip.

You have bypassed  the load by advancing the hands passed hr 24.

I make sure I have the right spring pushing the date jumper, lubricate the jumper mech and the date ring groove,  canon pinion might need a bit of tightening too. 

Worn date ring teeth is also a possibility in which case the ring is slightly pushed to the side.

Good luck

Hello Nucejoe, thank you very much for your advice. I'll further investigate and  share the results. this seems to be the original spring, but putting it back is a hell of a job 🙂! It take a lot of time and patience!

Hello Nucejoe, I promised to inform you after further investigation. The cannon pinion of the Parrenin consists of two parts (extra gear for friction). The cannon pinion was functioned oké. After lubrication of the jumper mechanism and the date ring groove, the watch runs very nice. So thank you again for your advice.

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.

      Smiths rim wind and set

      By transporter · Posted

      Ok, as per pictures I have a smiths rim set and wind on the bench, swimming in oil but all sorted. The fault I have is the mainspring bridle has lost its tab/notch/hook, like a hebdomas pocket watch the mainspring is fitted to a bridal in the barrel which slides around on full wind onto 4 notches in the barrel wall, thus stopping damage to the mainspring by over enthusiastic winding. So my questiion is this, what is the best way to create another hook in the bridal, my thoughts are along the same lines as making a new hole in the mainspring end, annealing etc, but what and how to make the hook?? I have a pair of barrel hook pliers that work great in soft brass but won’t even scratch the bridal, what I don’t want to do is whack a hole into it and not have a hook. the pictures are of the bridal ( broken) and a hebdomas ( complete ) incase you are wondering what I’m on about. And a few of the serivce. Thanks for any advise.

      Decided to give the case and bracelet a good cleaning and my first shot at polishing/brushing. Went with the Cape Cod polishing cloth and gray scotch brite method.  Before First; Then After; Then comparing to some original links from when the watch was new to now.

      It's either bent or hung up on something or both. The hexane won't hurt it, and hanging from a balance tack indefinitely won't hurt it.   If the spring is glued to the stud there's a chance that the glue was softened and the outer coil stuck to the stud. Haven't seen that happen, but I suppose it could. Don't know if hexane affects the glue used either.

      Hello all. some help required here from the community please. I serviced this movement, which was running reasonably well, but the balance spring which was running healthily before I started, after cleaning in hexane for 30 secs, is all bunched up at the stud. I did store the balalance on a tack thereafter for a day.   could the spring be strained under gravity? I demagnetised of course, and the balance is squeaky clean. some help would be much appreciated. Thanks, Tony G
