This former tech is baffled by the “cell coil”. There is no coil in the cell, which is what that dashed line implies.

There is a “phase sensing coil”, and a “circuit assembly” where the cell fits.

Ah, just not drawn right.

I'm sure that my watchmaker can do it. But I'm not sure that I want to spend 350+350 = 700€ for this watch. I'm tempted to retire from eBay, for a reason that I can't explain. Maybe it's my tendency to fix things, trying to save these pieces from the unavoidable destiny. Maybe it's just pride or because I'm stubborn.

In any case I understand that these movements are too delicate, too expensive and difficult to repair, correct me if I'm wrong. So I could just keep it as a reminder. Or I could dismantle it and put all the pieces in a frame to make a nice display, who knows!

DO NOT take it to pieces and put the pieces in a frame! Keep it as a donor, in case you need it to service another Accutron.

Difficult to repair? Not really, unless the parts you need aren’t available. Or, unless somebody who is not familiar with them is the one trying to repair them. The repair of an Accutron bears some similarity the servicing of mechanical watches, but there are many differences as well.

Expensive to repair? Could be because there are not a lot of people who will work on them, and the ones that do work on them tend to price their services accordingly. And there are times, because of parts availability problems, one needs to raid a donor watch for parts.
