2. Setup
2.1 Adjusting the Strap
The watch features a black 27mm FLEX strap with leather backed by silicone, designed to fit wrist circumferences up to 7.7 inches. To adjust the strap:

- Thread the end of the strap through the buckle and secure it by inserting the pin into one of the adjustment holes.
- Ensure the fit is snug but comfortable, allowing for slight movement without being too loose or too tight.

2.2 Setting Time and Date
Your watch is equipped with a crown and possibly pushers for setting. Refer to the following general steps:
- Time Setting: Pull the crown out to the furthest position. Rotate the crown to move the hour and minute hands to the correct time. Push the crown back in to secure the time.
- Date Setting: Pull the crown out to the middle position. Rotate the crown to adjust the date display. Be careful not to set the date between 9 PM and 3 AM, as this can damage the movement. Push the crown back in.
- Day Setting: If your watch has a day subdial, it is usually adjusted by rotating the crown in the middle position in the opposite direction of the date setting, or by advancing the time until the correct day is displayed.
- 24-Hour Subdial: This subdial typically synchronizes with the main time display and does not require separate adjustment.
3. Operating Instructions
3.1 Reading the Multifunction Dial
The GUESS GW0203G3 features a black sunray dial with three multifunction subdials:
- Day Subdial: Displays the current day of the week.
- Date Subdial: Displays the current day of the month.
- 24-Hour Subdial: Indicates the time in a 24-hour format, useful for distinguishing AM/PM and tracking international time.
The main hands indicate the current hour and minute. The small second hand is typically located on one of the subdials or as a central sweep hand, depending on the specific movement.
4. Maintenance
4.1 Water Resistance
Your watch is water resistant to 50 meters (165 feet). This rating means it is suitable for short periods of recreational swimming. It is not suitable for diving, snorkeling, or prolonged water immersion. Avoid operating the crown or pushers while the watch is wet or submerged to prevent water intrusion.
4.2 Cleaning Your Watch
To maintain the appearance of your watch:
- Wipe the case and crystal with a soft, dry cloth.
- For the silicone strap, a damp cloth with mild soap can be used, then rinse thoroughly and dry completely.
- Avoid using harsh chemicals or abrasive materials, as these can damage the watch's finish.
4.3 Battery Replacement
The watch operates on 1 AA battery (included). When the watch stops or the hands move erratically, the battery may need replacement. It is recommended to have battery replacement performed by a qualified watch technician to ensure proper sealing and maintain water resistance.
5. Troubleshooting
If you encounter issues with your watch, consider the following common solutions:
- Watch Not Running: Check if the crown is fully pushed in. If the watch still does not run, the battery may need replacement.
- Incorrect Time/Date: Refer to Section 2.2 for instructions on how to reset the time and date. Ensure the crown is fully pushed in after setting.
- Condensation Under Crystal: This may indicate a loss of water resistance. Avoid further contact with water and seek professional service immediately.
For persistent issues, please contact customer support or a certified watch repair center.
