I was trying to identify the watch my grandma gave me, after my grandpa passed away several years ago. Back then I wasn't into watches and it didn't really fit me, so it went into a drawer and came back to light just recently. But I fail to identify what model it is, since it has absolutely no model name or reference on the outside. I failed to open the back, since I don't want to damage it.

What I know:  
\- Quartz movement which isn't working  
\- case likely gold-plated, champagne/gold-ish dial  
\- 35.3mm wide, 40.2 lug-to-lug, 11.7 thick, lug widt 18mm  
\- I think it's from the 90s to mid-00s, ChatGPT suggested it rather is from the late 70s to mid 80s  
\- It couldn't be very expensive back then, bc my grandparents weren't very wealthy  
\- I suspect it to be bought in Germany, as they lived here for many years before moving back to their home country Serbia  
\- "SWISS MADE" underneath the 6h marker

I also added a screenshot the ChatGPT summary for some add. info

My grandpa wore it daily for years, and you can clearly see the marks it left over the years.

So yeah, I was wondering if you might be able to identify this watch. I want to get it back to life, buy a new strap that suits it better, and add it to my (cur. 2 watch) collection as my classic dress watch, since it really appeals to me now.
