Omega Seamaster Quartz Gold Diamond 1425

I got a watch inherited from my grandpa who sadly passed away when I was very young about 20 years ago. I was wondering if you guys could help me tell me more about the watch I have, where it’s from when it was made and perhaps the value of it. Basically just any information on it because I haven’t been able to find any watches like it. Also the dates on the dial are in Spanish and my grandpa was from Ecuador, but he could have gotten watch anywhere in South America.
Any help would be great! Thanks!

As a reminder of your grandfather it is priceless.

The dollar value of this watch might be $ 300. Its not a model that would be valuable or collectable.

Okay sounds good thank you! Even with the diamonds on it though?

Oh definitely, I don’t plan on ever selling it what’s so ever, I’m gonna get a battery on it but I think I can only do that at an omega store right? Or does any watch store repair watches battery?

Most watch stores can put in a new battery.
