3. Setup
3.1 Initial Winding
Your Bulova Marine Star 98A228 is an automatic watch, meaning it is powered by the motion of your wrist. Before wearing for the first time or after a period of inactivity, it is recommended to manually wind the watch to initiate power reserve.
- Unscrew the crown (if it is a screw-down crown) by turning it counter-clockwise.
- Pull the crown out to position 1 (the first click).
- Turn the crown clockwise approximately 20-30 times. This will build up an initial power reserve.
- Push the crown back into its original position and screw it down clockwise to ensure water resistance.
3.2 Setting the Time
- Unscrew the crown (if applicable) and pull it out to position 2 (the second click). The second hand will stop.
- Turn the crown to set the hour and minute hands to the desired time.
- Once the time is set, push the crown back into its original position and screw it down clockwise firmly to maintain water resistance.

3.3 Adjusting the Strap
The watch features a gray textured silicone strap with a buckle clasp. Adjust the strap by inserting the pin into the appropriate hole for a comfortable and secure fit on your wrist. Ensure the strap is not too tight to allow for proper circulation, nor too loose to prevent the watch from moving excessively.
4. Operating the Watch
4.1 Automatic Movement
The Bulova Marine Star 98A228 is equipped with a self-winding automatic movement. This means the watch is powered by the natural motion of your arm. When worn regularly, the watch will continuously wind itself, eliminating the need for manual winding or battery replacement. If the watch is not worn for an extended period, it may stop and require manual winding as described in Section 3.1.

4.2 Luminous Hands and Markers
The watch features luminous hands and markers, which absorb light and glow in low-light conditions, allowing for easy readability in the dark. Exposure to bright light will enhance the luminosity.
4.3 Water Resistance
This watch is water resistant up to 200 meters (660 feet), making it suitable for swimming, snorkeling, and recreational diving. Ensure the crown is fully screwed down before any water exposure. Do not operate the crown or pushers while the watch is submerged in water.
5. Maintenance
5.1 Cleaning
To maintain the appearance of your watch:
- Wipe the case and crystal with a soft, dry cloth.
- For the silicone strap, use a mild soap and water solution, then rinse thoroughly and dry completely.
- Avoid using harsh chemicals or abrasive materials, as these can damage the watch's finish or strap.
5.2 Water Resistance Care
To preserve the water resistance of your watch:
- Always ensure the crown is fully screwed down before exposing the watch to water.
- After exposure to saltwater, rinse the watch with fresh water and dry it thoroughly.
- Have the water resistance seals checked periodically by an authorized service center, especially if the watch is frequently exposed to water.
5.3 Mineral Crystal Care
The watch features a mineral crystal. While durable, it is not entirely scratch-proof. Avoid contact with abrasive surfaces to prevent scratches.
6. Troubleshooting
6.1 Watch Not Running or Stopping
- Cause: Insufficient power reserve.
- Solution: Manually wind the watch by turning the crown clockwise 20-30 times (after unscrewing and pulling to position 1). Wear the watch regularly to keep it wound by wrist movement.
6.2 Inaccurate Time
- Cause: Watch is not fully wound or has been exposed to strong magnetic fields.
- Solution: Ensure the watch is fully wound. If the inaccuracy persists, the watch may require demagnetization or servicing by an authorized Bulova service center.
6.3 Water Inside the Watch
- Cause: Crown not properly screwed down or seals are compromised.
- Solution: Immediately take the watch to an authorized service center. Do not attempt to open the watch yourself.
