2. Initial Setup
2.1 Unpacking and Inspection
Carefully remove the watch from its packaging. Inspect the watch for any visible damage. Ensure all protective films are removed from the crystal and case back.
2.2 Setting Time and Date
Your GUESS GW0571G1 watch features a multi-function quartz movement. The crown (located on the right side of the watch case) is used to set the time and date.
- Pull the crown out to position 2: This is typically the outermost position. The second hand will stop.
- Rotate the crown: Turn the crown clockwise or counter-clockwise to set the main hour and minute hands to the correct time. Ensure you set the AM/PM correctly if your watch has a 24-hour indicator.
- Push the crown back to position 1: This is the middle position.
- Set the Date: Rotate the crown in position 1 to adjust the date sub-dial. Some watches require rotating the crown in one direction for the date and the other for the day. Refer to the specific movement instructions if available.
- Set the Day of the Week: If applicable, rotate the crown in position 1 to adjust the day of the week sub-dial.
- Push the crown back to position 0: This is the normal operating position, closest to the watch case. The second hand will resume movement.
Note: Avoid setting the date between 9 PM and 3 AM, as this can interfere with the automatic date change mechanism.

3.2 Multifunction Dial
Your watch features a multifunction dial with sub-dials for:
- Day of the Week: Typically located at the 9 o'clock or 12 o'clock position.
- Date: Often located at the 3 o'clock or 6 o'clock position.
- 24-Hour Indicator: This sub-dial displays the time in a 24-hour format, useful for distinguishing AM/PM.

3.3 Water Resistance
This watch is water resistant to 50 meters (5 ATM). This means it is suitable for short periods of recreational swimming, but not for diving or snorkeling. Avoid operating the crown or pushers when the watch is wet or submerged, as this can compromise the water resistance.
- 50 Meters (5 ATM): Suitable for showering, bathing, and shallow swimming.
- Not suitable for: Diving, snorkeling, hot tubs, or high-pressure water activities.
4. Care and Maintenance
4.1 Cleaning
Wipe the watch case and strap regularly with a soft, dry cloth to remove dust and dirt. For silicone straps, a damp cloth with mild soap can be used, then rinse and dry thoroughly. Avoid using harsh chemicals or abrasive materials.
4.2 Battery Replacement
The watch is powered by one Lithium Metal battery (included). When the watch stops or the second hand begins to skip, the battery may need replacement. Battery replacement should be performed by a qualified watch technician to ensure proper sealing and maintain water resistance.

- Time or Date is incorrect:
