I'm in the process of refurbishing a 1913 trench style watch. The spring was needing replaced but unfortunately the new one from the suppliers had the wrong fitting at the barrel end. Due the cost of postage to return it, I thought I would modify it to fit the watch.

A few years ago I purchased an old spring punch, more because I like buying tools rather than I thought I might need it. I had a practice run on the old spring (the one in the photo) and annealed the end before using the punch. The result wasn't to good, so I tried it again without annealing and got the result you see in the photo. I now snapped the end off the new spring and punched a neat hole in it. Bearing in mind that the spring is only 1.3mm wide, I was well pleased with the result.

If you get the chance to purchase one of these punches at a good price, I would recommend you buy it.

Geo good result.

I have been looking for one of these for a long while, got outbid last year on one. A real handy tool that also comes in a bigger version for clock springs. Also interesting you got a better result without annealing.

When I annealed it, the metal was for want of a better description, chewy. This resulted in the spring trying to fold, and a sharp flashing was left once it was punched. When done without annealing, there was no folding effect and the hole punched crisply without any flashing.

      A lathe with indexing that won't break the bank?

      By coreymsnow · Posted

      Hi folks, I'm doing some homework on getting a watchmaker's lathe, and it's clear I have a lot to learn. But I know one goal: I want to be able to fabricate wheels, which would require an indexing capability. I know how to use large lathes- like, giant metal lathes- but my experience is a few decades old now (but you never forget the smell of the metal cutting oil). So I'm looking to learn anew, and have a goal to get to a point where I can fabricate some basic watch parts. I also have no specific timeframe and want to do this right, so I'll be patient and learn what I need to before spending the money. I know I'm not going to get anything for a pittance, but I'm also not really able to put together the scratch for a $5-$10k lathe. What's out there for a hobbyist that can either handle some fabrication out of the box or can be relatively easily made to do so? Thanks!

      Hello and welcome to the WRT forum.   This usually points to broken balance pivot.  Though a watch in need of clean & lube can do the same. Easiest diag would be to  see if balance pivot doesn't stay in hole jewel of the setting, when you lift one side of balance rim with an oiler or gently with pair of tweezers. Another would be to detach balance complete from the cock and take a look at pivot under high maginfication.  Regs

      Help with Hermle ships clock

      Ahhh, yes.  I hadn’t thought of that.  I’ve serviced quite a few of these and the first time I didn’t realise it was a ships strike pattern!  Ha ha, confused me totally until I realised.

      Help with Hermle ships clock

      By Rixy · Posted

      Hi Mike, I did, thanks. Found this clip that was really helpful:   It says Seth Thomas but it's actually the same Hermle I've been working on. I'd had it working correctly all along but hadn't noticed that the lever with the sprung end stops the hammer a bit short of the bell on the second ding at the end of the half-past sequence. If only I'd put the bell on when testing, rather than just looking at the hammer, my ears would have told me it was working,  even if my eyes didn't!
