Quartz movements, unlike mechanical or automatic movements, have few or no moving parts. A varying electric voltage is applied to a quartz crystal, and it resonates at a highly stable frequency, which is then used to accurately pace a timekeeping mechanism. Quartz movements are primarily electronic but are often geared to drive mechanical hands on the face of the watch to provide a traditional analog time display. Quartz-powered movements are considerably more accurate than their mechanical counterparts.
Did you know?
In 1959, Epson – the company considered to be the brains of the quartz movement - started developing a quartz wristwatch for parent company Seiko. Seiko had a working prototype ready by 1964, and it was used as the official timekeeper for that summer’s Tokyo Olympics.
CHANGING & SETTING THE TIME
Step 1 – Pull out the Crown
Remove the watch from your wrist and pull out the crown (button usually on the right side of the case). Do not pull too hard, as excessive force could cause damage.
Step 2 – Set the Date
Pull the crown out one notch, and turn clockwise. Keep rotating until you reach the desired date.
Step 3 – Set the Time
Pull the crown out to the 2nd notch, and turn to adjust the time. For models with a date feature, make sure to correctly set the time to AM or PM.
Step 4 – Closing the Crown
When the time and date have been set, push the crown back in towards the case.
