This ETA 811 based Titus has me beaten, at least for the time being. I suspect it will be a "long term project", where long might turn out to be infinite.
The thing will now run, having been previously locked up solid with grunge, and the after effects of some other ham-fisted individual pulling it apart and not quite putting it all back together correctly.
It needs a balance, since the HS is mangled, the jewel is missing and both pivots are gone.. and so is the stud. Whether I am willing to spring for £20 or so for that, given the over all condition of the rest of it, I don't know.
It also needs hands.. all three of them (I may have a suitable hour and minute, but not the second), and a crystal, and the lead solder holding on one of the lugs removed and replaced with silver solder, and a dial you can actually read, which isn't full of dents, that would be nice too.
If I put in all that work, it would be quite an attractive watch, but is it worth the time and expense I wonder.
They do turn up in some interesting watches, this for example according to the seller has a BG 866 variant.
.. and I must confess that if one of those turned up in need of parts, I too would be tempted to perform a partial brain transplant with the poor old Ackro De Luxe as the victim.
