Just to chime in. I've had a restauration done 2 years ago of my dad's old watch. It was similair to this one (a gold plated Bulova, about the same age I guess). Costs weren't that high. I got a new gold plating, 10 micron, which was only around €80, say $110. Omega itself uses a much thicker layer of gold if I'm correct, 30 or 40 microns. Also my usual watchmaker serviced the movement and I got new generic hands, a new generic crown and a new generic crystal. Total cocts was around € 200. Any watchmaker could do it. But, for me, it was important to restore the watch and be able to wear it. I didn't really care searching for original parts. Put a nice croc strap on it and it's like new! Be sure to bring tisseus when your mom sees it
