For sale is my 1960s Guildcraft by Gruen watch. Runs and keeps good time. $175 including shipping CONUS.
It is a sister brand of Gruen (Swiss brand), called Guildcraft. It has a swiss 17 Jewel movement, manual wind, non-hacking. Bi-directional bezel. I have not had it pressure tested, and don't even know its water resistance level. It does have a screw on caseback. I don't even use my dive watches near water, so in my possession for the last couple of years, it has seen none. Haven't seen the movement, haven't taken off the caseback.
