Hi
@Shams123 and welcome to the forum. Your watch looks fine. It even has an original crown, which is a good sign that the watch has been cared for over many years. It's a classic Tissot from the late 1940s to early 1950s with a "bumper" automatic. Once you get a peek inside, the serial number on the movement can be used to identify the exact year of production.
You can find similar examples at auction for about $150 so you can maybe bargain the seller a little lower if you're in the mood to do so. Carefully check the gold plating at the edges of the watch case, as this plating can wear away to the base metal.
You will need to service your watch at a vintage watchmaker. At a minimum, the mechanical movement inside your watch will need to be disassembled to check for wear and tear, then cleaned, lubricated, and adjusted. After that, it will make a reliable timepiece for many years.
If you buy the watch, don't forget to come back here to post pictures of it on your wrist.
