Crazy Pocket Watch Fix

Ok, got this pocket watch not working. Made a balance staff and cleaned it up and works great. Problem I had is that some bat watchmaker out a blob of solder at the 1 o’clock position on the case, to hold in the leaver that needs to be in to set the watch. So, I got out my torch, remover the solder. Then I took a piece of mainspring, doubles in over (using heat) and formed it to slide into the gap between the movement and the case: to hold in the leaver. Much better fix and works great.063fa7295097de6819fc89608e347e23.jpg872f9d2fb05ef1c9a328f2bcdbb8dc97.jpgd653af252dcade6f6cdd8327e116a874.jpg33a748c5492e4c3c68f470e7b86d6ec3.jpg5daf2ccbe01e83f3ee68b33b46eafcdf.jpg The beat error is a little high but the Amplitude is around 230, with a swing way over 450 degrees. And it sets the time wonderfully.

Your thinking cap came in handy. Many repairers just reach for the soldering iron and sod the consequences.

I love a puzzle. I thought if I do this and the movement needs servicing in the future, the small piece of folded over mainspring can be easily removed.

      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
