Following. I’m in Webster (south of Worcester) and found Joseph’s Jewelers in Putnam , CT (just over the border into CT) who did watch repair in-house (they did not send out) which was what I wanted. They fixed three vintage Omegas and cleaned up a quartz vintage Bulova I had and it was very reasonably priced. They also replaced a battery for me in a novelty watch.

I would vouch for them as a good choice if you are unsuccessful in Worcester. The father and son both work on watches and they also services clocks.

I know it’s not what you asked but I hope it still is useful. And I hope to hear about more choices - I’d love to find a dedicated horologist in Worcester.
