Movement
Hi Jovan,
Very nice to have a watch of your fathers. I agree that it looks late 1950's. What diameter is the case (excluding the crown)? Are you able to remove the case back and post a photo of the movement and tell us any markings/numbers? I assume the movement is hand wound (manual)? The 17 jewel movements, of which there were several used over this time period, were reliable workhorses. Your watch may well contain a Calibre GP27 (AS1130) which has a particularly attractive architecture as well. You may consider having it serviced if it has been more than 5-10 years and you wish to use it regularly. The textured dial is rather nice. Enjoy.

Inside of unknown GP
Hello Andrew, Thanks for the reply. The diameter of the watch is 35mm. And yes, the movement is MANUAL. I don't know much about watches so I could not tell you anything about the Calibre. Here is a photo of the inside and the back cover. There is a number...
This is a Cal. GP03
... a manual wind, 13 Ligne (about 29mm) movement beating at a leisurely 18000vph and with a power reserve of 41 hours. It was made until the mid 1940's but still being cased up into watches in the late 40's. It is difficult to give you information on the...
