SEIKO KINETIC Cal. 5M54 is an analogue quar tz watch equipped with the Kinetic technology
developed by SEIKO. It generates the electric energy to power the watch, utilizing the movement of
your body, and stores it in the rechargeable battery, which requires no periodical replacement unlike
conventional button-type batteries.

. When the watch stops completely, or if you find

the second hand moving at two-second intervals,
swing the watch from side to side at a rate of
twice a second.

1. By swinging the watch

2. By using the KINETIC Energy Supplyer YT02A

2. 250 swings will reserve up to 1 day of power.

The second hand will start moving at one-second intervals.

Set the crown to the 5M position.

•

Make sure tha t the w atch i s correctly

positioned as it may affect the amount of
power generated.

•

The amount of power generated may vary

depending the models of the watch.

5M

Cal. 5M54A is equipped with a power reserve indicator. The current power reserve can be checked by
reading the posisiton of the second hand after pressing the button at the 2 o'clock position.

*

The second hand will resume normal movement after the indicated 5, 10, 20 or 30 seconds have
elapsed.

*

To allow easy reading of the second hand, press the button when the second hand is at the 12 o’clock
position.

*

It is recommended that the watch be swung further until 2 days of power is reserved. As a
guideline of recharging, additional 200 to 250 swings, about 450 to 500 swings in total will
reserve 2 days of power.
