Energy Depletion Forewarning Function; Instant-Start Function - Seiko Cal. 3M22 Instructions Manual

ENERGY DEPLETION FOREWARNING FUNCTION

When the energy stored in the capacitor is reduced to an extremely low level, the second
hand starts moving at two-second intervals instead of the normal one-second intervals,
indicating that the watch needs recharging and will run down in approximately 3 hours
(Cal. 3M22/4M21) / 6 hours (Cal. 5M42/5M43).
If you find the second hand moving at two-second intervals, therefore, be sure to swing
the watch from side to side to charge the capacitor sufficiently before using it.
Note: The watch remains accurate even while the second hand is moving at two
second intervals.

INSTANT-START FUNCTION

This function is very useful when a watch has been stopped for a long time and you
need to get it started quickly with only a few swings.
This function is available as long as:
1) the watch previously had more than 2 days (Cal. 3M22/4M21) / 4 days (Cal.
5M42/5M43) of power reserve before it stopped.
2) it has been left untouched for 1 to 4 weeks.
