How do I identify my Gruen watch?

To identify a Gruen watch, look at the back of the case. Most timepieces will display a series of digits and then a hyphen or a forward slash followed by another series of digits. The first set of numbers represents the caliber of the movement, while the second set is the style number of the watch. Once you have located these numbers, you can use trusted online resources to learn more about your timepiece. A certified appraiser or antiques dealer who is knowledgeable about watches may also be of assistance in identifying your timepiece. Shop an assortment of Gruen watches on 1stDibs.
