I have several of these-running and not. Who works on these? I would like one daily reliable wearer. Thanks.

In theory anyone can work on these. If you are asking if there is a specialist with parts for these watches I have no idea (the movements aren't terribly expensive so you could get a boneyard going with ease). I have a question for anyone who has experience with these.. anybody?

I got a couple of 761s up and running. Maybe I can help?

Much as I love these, I wouldn't use one as a daily wearer. Nobody's making new parts, and there are 3 pieces that are prone to breakage. The dozen I have get maybe 1 day each of wrist time every 2-4 months. Some of them will still be running the morning after a day on the wrist, some won't. If you have to set the time every day, you're putting stress on the set bridge. If you have to wind it up, you're putting stress on the winding wheel on the rocker, and the lower pivot of the 2nd autowind wheel.

WRT service, any competent watchmaker should be able to handle them.

genejockey is right on this one however I do wear mine often. I have at least 25 examples that I got running good in my keeper selection.
Parts are the most difficult thing on these. movements don't come too cheap and usually have issues as gene said.I have piles of movements with the same broken parts. All that said I enjoy them very much and they are possibly my favorite Elgin movements. Servicing them is not that much different.

I tore one of these down to overhaul and stopped because I was confused about the condition of the mainspring & barrel.... the end of the mainspring (see pic) does not look like a modern automatic bridle. Inside the barrel wall I found no evidence of any notches (of course they could have worn away). I assume I need a barrel that is not worn beyond practical use. What does a new mainspring for these look like? Thanks in advanced!
