Hello, and welcome to the forum!
All of the information you would need to help you learn more about your watches is contained inside them. You will need to take your watches 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 watches without scratching or damaging them.
Inside each watch is a serial number that will help you date the year the watch movement was manufactured. If you intend to wear your watches, you should 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 some lovely heirlooms that are worth a little love and attention, and in return you will have timepieces that will last your decades with some routine maintenance.
