Important notes for automatic winding watch

Dear Seiko owners,

Today, SEIKO has two types of mechanical watches—automatic winding and hand winding. Although automatic ones are regarded
as convenient watches without the need to wind up like hand winding watches and to replace batteries like quartz, automatic mechanical
watches need to be wound up. Above all, this is a mechanical watch.

If the watch is worn on the wrist, the mainspring will be wound automatically through normal wrist movement.

To start the watch after it stops completely, or after being repaired, wind it up by shaking from side to side until it becomes almost
fully-wound (See the below picture). Then, set the time, date and day before wearing the watch on the wrist.

Once the watch is wound up fully, it operates from 40 to 50 hours approximately. If the watch is used without being wound up fully, a
gain or loss of time may result. To avoid this, it is recommended that you wear the watch daily for more than 8 hours.

To wind the watch fully
1 Hold the watch with the face side up
2 Shake the watch from side to side (2 times/sec.) for 7-10 minutes roughly.
