I had a F-91W for years, I still have it and it still works, but like you I moved to an automatic Seiko 5 (the smallest I could find as my wrist is quite thin), for two reasons I wanted something more good looking, and I didn't want to worry about batteries (although they last years)

I did the opposite. Wore a Seiko 5 for a while until I got tired of not trusting it, then switched to an F91w. The Seiko is very good for an affordable automatic, but it’s hard to beat a quartz for “it just works”.

It sounds like yours needed regulation. Properly regulated you can trust them just fine.

It wasn't out of spec, I'm just referring to the general weaknesses of automatics. If I spend the weekend doing physical activity where I don't want to wear a watch, Monday morning I'll be resetting my Seiko 5. With my F91w, I can take a long vacation, and spot check a system clock to the second when I get home.

Ah, I see, that's what you mean with reliability. Ok. I wear mine pretty much all the time so that's the reason I'd never have that problem. I thought you meant accuracy. Thanks for the clarification.
