Welcome to the forum. If you are curious to know more about your heirloom, we recommend that you take your watch to a watchmaker who has the tools to remove the back of the watch without scratching it. As noted above on the inside of the caseback you will find a case reference number that basically serves as the "model name" for your watch. The mechanical movement will contain a three-digit number that identifies the type of movement (known as the caliber), as well as a serial number that can be used to date your watch.

 

Thanks, I appreciate you’re help, I’ll do that next week.

 

Thanks for the help.
