Hi all, This is a Gruen PanAm "Ace" in really great condition. I've had my watchmaker service the movement but don't have paperwork to go along with it (so I won't claim it's serviced or price it as such.... but it is....) Keeps great time and will come on the new strap you see. As far as I know, this would be from around 1946-48. I have been around for several years and have bought and sold many. I can provide references. I'm looking for USD 275 shipping included. N. America preffered. PP F&F Thanks for reading.
