I've had my Bulova Precisionist for just over a year now. Over that time, I've only adjusted the date each month. I had never adjusted the time to reflect daylight savings time just to see if its accuracy would hold up to its advertised 10 sec/year. I wear the watch about for a few hours a couple of days a week (usually on weekends, in the pool, yardwork, etc.).
So how did the watch perform??
An astounding +5 seconds over 365 days. It was running about +2 seconds until the heat wave hit this past summer.
Conclusion? A quartz watch with a continuous sweeping movement and accuracy that would make the best of them envious. And less than 500 bucks to boot.
oh yeah...the obligatory pic of the watch..
