Hi Everyone, To cut a long story short I broke the regulator arm on my pocket watch from approx 1895. The regulator arm was loose and I tried to tighten it by squeezing. I shouldn't have been so stupid. I know that now. Any ideas how I can source one that will fit? I have attached a picture of the exact same style to the one I need. Inner diameter of the regulator arm where it fits around the jewel setting is approx. 4.3 mm. Hairspring is overcoil type. Thanks for any help in advance.

unfortunately in watch repair it's the painful lessons we remember.

finding spare parts for vintage watches is always going to be a challenge. Then a unidentified watch makes things even more challenging. If you cannot find one you could always regulated and use a small amount of glue to hold it in place. Not ideal but you may not be of a find one right away

I don't suppose we can have a picture of the dial side without the dial just because I'm curious about something.

I wonder if the broken parts was original at all. Looks a bit strange.

I am sure it is correct as I see that style used on quite a few English watches of that period (eBay listings mainly)

Hi John,

 

I will send a picture when I rebuild that side. Is that OK? Or is a picture of the empty plate what you need?

Make one out of carbon steel. 

I did have that very thought but drilling the tiny holes (approx 0.1 mm dia) for the two curb pins has put me off the idea as I don't have a pillar drill. Might give that a go though at some point if one doesn't turn up.

what I was curious about was if you look at the dial side plate can you see the scribe marks were somebody hand laid out the wheels? It would give us an indication as to whether this was mass-produced or whether it was basically hand assembled.

Another issue has been found unfortunately. Appears that the balance staff is too short with the roller table sitting on the pallet fork and the balance rim sitting on the pallet fork cock. I don't think the watch has run in that state. Time to give it back I think.

Interested if anyone knows what T.H on the rear plate signifies. Could it be a makers mark as I can see no other marks on the watch.

Does anyone know the significance of the T.H mark on the rear plate?

      Tissot case back removal

      By watchweasol · Posted

      The ones I have opened also do not have a pry point , hence the reason for the tool. The watch is clamped in the tool and a blade is screwed into the seam, the blade being chamfered lifts the back then the screw shaft is turned and the back comes off have a look on Ali express for case back removal tools

      By jhoho202 · Posted

      I don't think I need to know more about the Orient watch question, so please don't write anything related to the topic, but if you know where I can buy the watch's jewels = rubies and gems shock protection, I would like to know.

      It's an exhibition back so no access as you suggest.

      Phinney Walker Mickey Mouse Watch HELP

      I have no experience with this watch, but looking at the pictures from the ebay listing linked above, it looks like the outer metal bezel at the back of the watch may not be part of the case proper.  It looks like the watch and strap are sandwiched together, and an inner case may push out of the rear bezel towards the front of the watch.  A case style similar to the Roamer watches where the crystal, movement and caseback pushed out through the back of an outer bezel, only in reverse - this one may push out towards the front.  To test this, you would need to hold the watch, dial down, supporting the dial side of the watch around the edge of the bezel without touching the bezel itself. Then push down carefully on the inner metal ring you can see at the back of the watch. I’m speculating here, proceed at your own risk. Hopefully someone with hands on experience of these watches can chime in! Best Regards, Mark

      Thanks, Mark. That's the kind of reassurance many of us wanted to hear! Yes, life is unfortunately unpredictable, and it would be a shame if the many dedicated WRT: ers became stranded if, god forbid, something happened to you and WRT stopped working.
