I don’t know how to tell the size very well but it has a 1 5/8″ face and is about 2″ edge to edge on the case. Serial number 92051 on the movement and Agassiz is all the markings available. The case is a pretty nice hunter made by the Columbia SX co. I’m pretty sure it is 15KGP but also not marked. I know these were very high quality watches and this one is a great one to restore and use…….. This item is in the category “Jewelry & Watches\Watches, Parts & Accessories\Watches\Pocket Watches”.
