How To Start The Watch:

To start the watch for the first time, unscrew the crown and wind it up fully.

To start the watch, hold it as shown in the illustration and swing it from side to side in a horizontal arc for about 30 seconds.
NOTE: If worn daily, SEIKO’s automatic mechanism will wind the mainspring automatically through normal wrist movement, eliminating the need for additional winding.

How To Set Time And Calendar:
The date changes automatically each day at about midnight. This change can also be made manually as follows:
1. To set the time – Pull the crown OUT all the way to the SECOND click (Cal. 2205 to the FIRST click) and set the time. Then push the crown IN.
2. To set the calendar – Cal. 6159, 6105 watches:

How To Set The Second Hand:
Cal. 6159, 6105 watches:
The sweep center hand (second hand) STOPS when the crown is PULLED OUT and resumes moving when the crown is returned to the normal position. By pulling the crown out and pushing it back to normal in coordination with a time signal, it is possible to set the sweep center hand to the exact second.

HI-BEAT WATCHES:
Cal. 6159 watches have a frequency of 36,000 per hour, twice that of ordinary watches. HI-BEAT watches can keep more precise time during actual use than ordinary watches, because the high frequency movements are less affected by shocks and wrist movements.

UNIQUE CROWN-LOCKING DEVICE:

After using the crown, return the crown to the NORMAL position by pushing and screwing it.
(for Case No. 6105-8110 watches)

ROTATING BEZEL (TO EXACTLY CALCULATE ELAPSED TIME):
The ‘▼’ mark on the rotating bezel can be turned to mark the position of the minute or hour hand. This permits exact calculation of elapsed time.

TO PRESERVE THE WATER RESISTANT QUALITY OF YOUR SEIKO WATCH:
(For Cal. 6159, 2205 watches) – Before using in water, make sure the crown is screwed on tight.
Do not operate the crown when the watch is wet or in water.
After the watch is used in water, or when it is wet, wipe it thoroughly dry. When it is exposed to sea water, rinse it in fresh water and then wipe it dry.
