This is a Gruen Precision model reference 422-973. It has a handwinding movement and the 30mm case is in overall amazing condition, fits nicely on my 7" wrist. Price: $275 The dial is beautiful, and the case and hands are in great shape, one minor scratch (4th photo) to the crystal. Note the intentionally curved minute hand to mirror the profile of the dial and the Gruen signed crown! Sold as is but seems to be running and winding very well. Comes with an awesome Hong Kong made rubber strap with matching gold buckle. The Gruen Precision model was the first watch seen on screen in a Bond movie, worn by Sean Connery in "Dr. No." Shipping available, or Chicago local sales welcome.
