Instructions for Analogue Quartz and Mechanical Watches

This document provides instructions for six types of analogue quartz and mechanical watches. Before using a new watch, please read the instructions pertaining to your specific watch type to ensure optimal use.

Watch Types and Display

The watches are categorized by their display and hand configurations:

• A: Two hands without calendar
• B: Two hands with date calendar
• C: Two hands with day and date calendar
• D: Three hands without calendar
• E: Three hands with date calendar
• F: Three hands with day and date calendar

Display and Hands Overview

A typical watch display includes:

• Hour hand
• Minute hand
• Second hand
• Crown (often marked with a star ★)
• Date display
• Day display

★ Some models feature a screw-down crown instead of a standard crown.

• How to unlock the crown: Unscrew the crown by turning it counterclockwise. Then, pull it out for time/calendar setting.
• How to lock the crown: Push the crown back to the normal position. Then, turn it clockwise while pressing it until it locks in place.
• When using the watch in water: Before using the watch in water, ensure the crown is screwed in completely. Do not operate the crown when the watch is wet or in water.

How to Start a Mechanical Watch

• Cal. 4206, 4207, 4217, 7002, 7009, 7019, 4S15, 7S25, 7S26, 7S35, 7S36, 7S55: To initially start your watch, swing it from side to side in a horizontal arc for about 30 seconds.
• Cal. 4206, 4207, 4217, 4S15: These watches can also be started by winding the crown.

Note: If the watch is worn daily, SEIKO's automatic mechanism will wind the mainspring automatically through normal wrist movements.

How to Use the Watch

Set the time/calendar following the instructions specific to your watch type.

Time Setting for Models Without Calendar (Types A, D)

1. Pull out the crown all the way.
2. Adjust the time by turning the crown in the desired direction.
3. Push the crown back in to the normal position.

* If your watch has three hands, pull out the crown when the second hand is pointing to 12 o'clock. Push the crown back in to the normal position in accordance with a time signal for "00" seconds.

Note: When setting the minute hand of a quartz watch, advance it to a few minutes ahead of the time and then turn it back to the exact time.

Time/Calendar Setting for Models With Calendar

★ The date will change gradually between 9:00 P.M. and 4:00 A.M. For some models, it will change instantly when the hands pass the 12 o'clock marker at midnight.

For Models With Date Calendar (Types B, E)

1. Pull out the crown to the first click.
2. Turn the crown until the previous day's date appears in the calendar frame.
3. Pull out the crown to the second click, and advance the hour and minute hands until the desired date appears.
4. Adjust the time by turning the crown in the desired direction.
5. Push the crown back in to the normal position.

* If your watch has three hands, pull out the crown when the second hand is pointing to 12 o'clock. Push the crown back in to the normal position in accordance with a time signal for "00" seconds.

For Models With Day and Date Calendar (Types C, F)

1. Pull out the crown to the first click.
2. Turn the crown until the previous day's date appears in the calendar frame.
3. Turn the crown in the opposite direction until the desired language (bilingual) for the day before the desired day appears in the calendar frame.
4. Pull out the crown to the second click, and advance the hour and minute hands until the desired date and day appear.
5. Adjust the time by turning the crown in the desired direction.
6. Push the crown back in to the normal position.

* For Cal. 7009 and 7019, push the crown back in to the normal position and then push it repeatedly to set the day.

* If your watch has three hands, pull out the crown when the second hand is pointing to 12 o'clock. Push the crown back in to the normal position in accordance with a time signal for "00" seconds.

Notes on Calendar Setting:

1. Do not change the calendar between 9:00 P.M. and 4:00 A.M., as it may not change properly. If necessary to set the calendar during that time, first change the time to any time outside those hours, set the calendar, and then reset the correct time.
2. When the day shifts automatically to the next day, the other language will temporarily appear.
3. When setting the hour hand, check that AM/PM is correctly set. The watch is designed so the calendar changes once every 24 hours. Turn the hands past the 12 o'clock marker to determine whether the time is set for the A.M. or P.M. period. If the calendar changes, the time is set for the A.M. period. If it does not change, the time is set for the P.M. period.

Changing Battery in Analogue Quartz Watch

The battery is inserted at the factory to check the watch's function and performance. Its actual service life may be less than the specified period. When the battery expires, replace it as soon as possible to prevent malfunction. For battery replacement, it is recommended to contact an AUTHORIZED SEIKO DEALER and request they use only a genuine SEIKO battery.

Battery Life Indicator

If an analogue quartz watch has a second hand, the battery needs replacement when the second hand moves in two-second increments instead of normal one-second increments. (Some calibres do not have this function.) The watch will, however, remain accurate while the second hand is moving in two-second increments.

Loss/Gain of the Analogue Quartz Watch

Loss/gain (monthly rate) is less than 15 seconds (20 seconds for some calibres) in the normal temperature range (5℃ ~ 35℃ or 41℉ ~ 95℉).

To Preserve the Quality of Your Watch

Water Resistance

Water resistance varies by model and is indicated on the case back.

• Non-water resistant: If "WATER RESISTANT" is not inscribed on the case back, the watch is not water resistant. Avoid getting it wet as water may damage the movement. If it becomes wet, it is suggested to have it checked by an AUTHORIZED SEIKO DEALER or SERVICE CENTER.
• Water resistance (3 bar): If "WATER RESISTANT" is inscribed on the case back, the watch is designed to withstand up to 3 bar, suitable for accidental contact with splashes of water or rain, but not for swimming or diving.
• Water resistance (5 bar): If "WATER RESISTANT 5 BAR" is inscribed on the case back, the watch is designed to withstand up to 5 bar, suitable for wearing while swimming, yachting, and taking a shower.
• Water resistance (10 bar/15 bar/20 bar): If "WATER RESISTANT 10 BAR", "WATER RESISTANT 15 BAR" or "WATER RESISTANT 20 BAR" is inscribed on the case back, the watch is designed to withstand up to 10 bar/15 bar/20 bar, respectively. These are suitable for wearing while taking a bath or shallow diving, but not for scuba diving. For scuba diving, a SEIKO Diver's watch is recommended.

* Before using a water resistant 5, 10, 15 or 20 bar watch in water, ensure the crown is pushed in completely. Do not operate the crown when the watch is wet or in water. If used in sea water, rinse the watch in fresh water and dry it completely.

* When taking a shower while wearing a water resistant 5 bar watch, or taking a bath while wearing a water resistant 10, 15 or 20 bar watch, observe the following: Do not operate the crown when the watch is wet with soapy water or shampoo. If the watch is left in warm water, a slight time loss or gain may be caused. This condition, however, will be corrected when the watch returns to normal temperature.

Note: Pressure in bar is a test pressure and should not be considered as corresponding to an actual diving depth since swimming movements tend to increase the pressure at a given depth. Care should also be taken when wearing and diving into water.

Temperature Range

[For analogue quartz watches only]

Your watch operates with stable accuracy in a temperature range of 5℃ and 35℃ (41℉ and 95℉).

Temperatures over 60℃ or 140℉ (50℃ or 122℉ for some calibres) may cause battery leakage or shorten the battery life.

Do not leave your watch in very low temperatures below -10℃ or +14℉ (-5℃ or +23℉ for some calibres) for a long time since the cold may cause a slight time loss or gain. However, these conditions will be corrected when the watch returns to normal temperature.

Shocks & Vibration

General light activities will not affect your watch, but be careful not to drop your watch or hit it against hard surfaces, as this may cause damage.

Magnetism

The watch can be adversely affected by strong magnetism. Keep the watch away from close contact with magnetic objects. For quartz watches, normal accuracy will return if the watch is moved away from the magnetic field.

Chemicals

Avoid exposing the watch to solvents (e.g., alcohol and gasoline), mercury (e.g., from a broken thermometer), cosmetic sprays, detergents, adhesives, or paints, as these may cause discoloration, deterioration, or damage to the case, bracelet, etc.

Periodic Check

It is recommended that the watch be checked once every 2 to 3 years. Have your watch checked by an AUTHORIZED SEIKO DEALER or SERVICE CENTER to ensure that the case, crown, gasket, and crystal seal remain intact.

Care of Case and Bracelet

To prevent possible rusting of the case and bracelet caused by dust, moisture, and perspiration, wipe them periodically with a soft dry cloth.

Precaution Regarding Case Back Protective Film

If your watch has a protective film and/or a sticker on the case back, ensure to peel them off before using your watch. Otherwise, perspiration getting under them may rust the case back.
