Another breakthrough in mechanical watch accuracy has been achieved with the introduction of the Zenith Defy Lab watch. The oscillator which does away with the balance wheel, hairspring and escapement, vibrates at 15Hz or 108,000 beats per hour giving this timepiece an accuracy of a little over .3 seconds per day, with an amplitude of +/- 6 degrees. This is truly amazing when compared to many of the higher end mechanical timepieces running at 28,000 (or 36,000) beats per hour and approximately 280 degrees amplitude with variations in this rate for the given position of the balance wheel.
