These are the four oldest watches I've had, except for one that's missing.
First a Citizen.
Then I got an Aetos.
After that, a Citizen Club 2000, which was my first quartz watch.
Missing is a Nivada Baby Whale with a white dial. It broke when I was in Fiji.
The replacement which I got in Australia is a Seiko SQ100. It's really good even though 20 years old, but the seal has worn out, so I don't wear it anymore and won't replace the battery when it runs out. (I've always had it showing the French weekday names.)
