| Other Features | The watch has a 'Zero Reset' seconds hand which resets the seconds hand to zero when you pull out the crown to adjust the time making it extremely easy to synchronize the watch to perfection. Date correction can be achieved either by pressing one button which will change all features collectively, or each complication can be corrected independently using recessed corrector buttons. |
