Hello, and welcome to the forum! All of the information you need to help you learn more about your watch is contained inside it. You should take your watch to a local watchmaker in your area, preferably one who is skilled in repairing vintage watches. The watchmaker has the specialist tools required to open your watch without scratching or damaging it.
On the watch movement is a serial number that will help you date the year the movement was manufactured. On the inside caseback is a case reference number.
If you intend to wear your watch, ask your watchmaker to service the watch. They will clean the watch movement, lubricate the many moving parts, and adjust the timing so that it is accurate. You have a nice heirloom that is worth a little love and attention, and in return you will have a timepiece that will last decades with some routine maintenance.
