Miyota 0S00

The Miyota 0S00 is a Japanese-made quartz chronograph movement with a day/date complication at 3:00. It maintains accuracy within ±20 seconds per month and uses an SR927W battery that lasts approximately five years. The movement belongs to Miyota's 0S "Professional" series and includes a stem-out feature that conserves battery life when the watch isn't being worn. It corresponds to Citizen's caliber 0500.
