Pocket watch regulator arm

[steve1811uk]

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?

Couldn't it be welded? Other than the general concept, I  know little about welding but I  know thin plate can be welded.

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.

Seems like Roterham Watch Co movement. They are not rare and parts a relatively interchangeable.

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?
