2.2 Setting Time and Date
Your GUESS U0479G2 watch is equipped with a quartz movement and a multi-function dial.
- Pull the Crown: Gently pull the crown (the knob on the side of the watch case) out to the first or second click position. The number of clicks depends on whether you are setting the date/day or time.
- Set the Date/Day: If the crown has a first click position, rotate it clockwise or counter-clockwise to adjust the date and/or day subdials. Avoid setting the date between 9 PM and 3 AM, as this can interfere with the automatic date change mechanism.
- Set the Time: Pull the crown out to the second click position (if applicable, or the outermost position). Rotate the crown to move the hour and minute hands to the correct time. Ensure you distinguish between AM and PM for the 24-hour subdial to function correctly.
- Push the Crown Back: Once the time and date are set, push the crown back into its normal operating position against the watch case to start the watch and ensure water resistance.

2.3 Bracelet Adjustment
The stainless steel link bracelet can be adjusted to fit your wrist. This typically involves removing or adding links. It is recommended to have this adjustment performed by a qualified jeweler or watch technician to prevent damage to the bracelet or watch.

3. Operating Your Watch

The main dial displays the hour, minute, and second hands for standard timekeeping.
3.2 Multi-function Dials
- Day Subdial: Indicates the current day of the week.
- Date Subdial: Displays the current day of the month.
- 24-Hour Subdial: Shows the current time in a 24-hour format, useful for distinguishing AM/PM and for military time.
3.3 Water Resistance
Your GUESS U0479G2 watch is water resistant to 100 meters (330 feet). This rating means the watch is suitable for swimming and snorkeling. It is not suitable for scuba diving or high-impact water sports.
- Ensure the crown is fully pushed in before any contact with water.
- Do not operate the crown or pushers while the watch is wet or submerged.
- Avoid exposing the watch to extreme temperature changes (e.g., hot showers followed by cold water), as this can compromise seals.
4. Maintenance
4.1 Cleaning
To maintain the appearance of your watch, wipe the case and bracelet with a soft, dry cloth regularly. For stainless steel, a slightly damp cloth can be used, followed by immediate drying. Avoid using chemical cleaners, solvents, or abrasive materials.
4.2 Battery Replacement
Your watch is powered by a product-specific battery. When the battery runs low, the watch may stop or the second hand may skip. Battery replacement should be performed by a qualified watch technician to ensure the watch's water resistance is maintained and to prevent damage to the internal components.
4.3 Storage
When not wearing your watch, store it in a cool, dry place away from direct sunlight, extreme temperatures, and strong magnetic fields. The original watch box is ideal for storage.
