CAL. 7R68 “SPRING DRIVE”

SPRING DRIVE MECHANISM

● Like a traditional mechanical watch, the mainspring drives the watch. What is new

is that it also runs a generator which in turn oscillates a quartz crystal. This regulates

the movement of the hands as accurately as a traditional quartz watch.

● The second hand moves smoothly without steps.

POWER RESERVE INDICATOR

● It shows the extent to which the mainspring is wound.

UP TO 48 HOURS OF CONTINUOUS OPERATION

● When the watch is wound fully, it keeps operating for approximately 48 hours.

Until now, quartz and mechanical watches existed as two distinct entities.

Driven by a mainspring, this watch delivers the accuracy of a traditional quartz watch

thanks to the use of the Spring Drive Mechanism newly developed by SEIKO.
