3. Setup
3.1 Initial Winding
Your SEIKO 5 Sports watch is powered by an automatic movement. If the watch has stopped, it needs to be wound to start. Gently shake the watch from side to side for about 30 seconds to initiate the movement. Alternatively, you can manually wind the watch by rotating the crown in the normal position clockwise for approximately 20-30 turns.
3.2 Setting the Time and Date
- Pull the Crown: Gently pull the crown out to the second click position. The second hand will stop.
- Set the Time: Rotate the crown to set the hour and minute hands. To ensure the AM/PM is correctly set for the date change, advance the hands past 12 o'clock. If the date changes, you are in the AM period. Continue to set the correct time.
- Set the Date and Day: Push the crown back to the first click position. Rotate the crown counter-clockwise to set the date and clockwise to set the day of the week. The day display supports both English and Spanish.
- Finalize Settings: Push the crown back to the normal position. The second hand will resume movement.

4. Operating Instructions
4.1 Wearing the Watch
Ensure the stainless steel bracelet is adjusted to fit comfortably on your wrist. The deployment clasp provides a secure fit. To open the clasp, press the buttons on the side of the clasp. To close, simply fold the clasp until it clicks securely.
4.2 Water Resistance
Your SEIKO 5 Sports SRPE51 watch is water-resistant up to 100 meters (10 BAR). This means it is suitable for everyday use, showering, swimming, and snorkeling. However, it is not designed for scuba diving. Always ensure the crown is fully pushed in before exposing the watch to water.
4.3 LumiBrite Display
The LumiBrite hands and markers absorb light energy from sunlight or artificial light and store it to emit light in the dark. The emitted light gradually diminishes over time. The duration and intensity of the glow depend on the exposure time and intensity of the light source.
5. Maintenance
5.1 Cleaning Your Watch
Regular cleaning helps maintain the appearance and longevity of your watch. Wipe the case and crystal with a soft, dry cloth. For the stainless steel bracelet, use a soft brush with mild soapy water to remove dirt and grime, then rinse thoroughly with fresh water and dry completely with a soft cloth. Avoid using harsh chemicals or abrasive materials.
5.2 Periodic Inspection
It is recommended to have your watch inspected by an authorized SEIKO service center every 2 to 3 years to ensure its water resistance and the proper functioning of the mechanical movement. This includes checking gaskets, lubrication, and accuracy.
6. Troubleshooting
6.1 Watch Has Stopped or Runs Irregularly
- Insufficient Winding: As an automatic watch, it requires motion to operate. If the watch has been stationary for an extended period, manually wind it or wear it for several hours to build up the power reserve.
- Magnetic Influence: Exposure to strong magnetic fields can affect the watch's accuracy. If you suspect this, consult an authorized service center.
6.2 Date or Day Not Changing Correctly
- Incorrect Time Setting: Ensure the time is set correctly, especially the AM/PM cycle. The date and day typically change around midnight. Avoid adjusting the date/day between 9 PM and 4 AM, as this can damage the movement.
- Manual Adjustment: If the date or day is incorrect, follow the "Setting the Time and Date" instructions in Section 3.2 to manually adjust.
