A little while ago I put a post on about a case I was thinking about have repaired. 

Why I'm not sure why, I was given it by an old friend, since then a lots happened, I unbelievably have found a case on EBAY, I'm hoping it's as good as the pictures. 

The movement is my next challenge, it's got water in it, as a lot of them did, so it's not brilliant, and the auto work is missing. 

The case back, looks like it's seen better days, but get the drill out and, hay presto.

Well the next step was the movement once I've cleaned up an got rid of all the rust from the inside if the case and case ring.

I had a couple of the eta 2472 movement's in various states of repair, I found one with the auto work intact, so I thought I'm in luck. 

So I cleaned and serviced it changed the date ring over and got it running, only to find out the the crown wheel and castle wheels where worn out, probably because had been wound but hand most of its life. 

The movement after I'd straightened the hairspring timed it I. Is now running like a dream. 

I'm just waiting on FedEx to deliver the case from Italy. 

Sorry about the drill picture on the previous post, it was the wrong picture and I didn't know how to replace it.

Not too sure why my posts get moved to the chat-about-watches-the-industry. 

As it was a walk through on one of my watches. 

Now moved to the best suited section, as the walk-throughs should have more pictures and details of each step taken. Thank you for your contribution and understanding.

      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.

      Replacing, upgrading Ronda 715 Harley?

      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
