>Have you checked high precision quartz watch mouvements? Longines, a Swiss watch manufacturer, uses a quartz mouvement called "Calibre L546" with +/- 10 seconds per year accuracy. It runs for 10 years (!) on a watch-size Lithium battery.
Apparently also Tissot has something similar. My Tissot wrist watch is
off about only a few seconds when I have to reset it two times per year
at the start/end of the daylight saving period. Or maybe I am just lucky.
