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 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.
