Gruen Diamond Dial cal 460

Here’s one I picked up for a daily wear watch that’s on the bench along with about a half dozen others right now. It’s a cal 460ss bumper which are a very easy movement to work on and the cross hair dial and diamond shape indices are a nice combination. The dial has received a dip in tarnish remover to take off the heavy patina and what’s left is flaking¬† lacquer to be dealt with later. there’s also a bit of rust on one bridge screw but it’s localized as far as I can tell so it shouldn’t be a problem. Updates to come.

Dealing with the rust on the hands is the biggest issue in this case since any significant removal of the metal will result in plating loss. New hands may have to be sourced to finish it off. What’s left is a simple overhaul of the movement which is in very good condition. The bracelet is in good enough condition to keep with the watch., so it’s on the wrist and being wear tested.
