Your Timex digital watch comes with a pre-installed lithium metal battery. Upon first use, or after a battery replacement, you may need to set the time and date.
- Press and hold the MODE button (typically located on the bottom left) until the time display begins to flash. This indicates you are in setting mode.
- Press the SET button (typically top left) to cycle through the settings: hours, minutes, year, month, day.
- Use the START/STOP button (typically top right) to adjust the flashing value up or down.
- Once all settings are correct, press the MODE button again to exit the setting mode and save your changes.
2. Adjusting the Strap
The watch features a black resin strap with a buckle clasp, designed to fit wrist circumferences from 142mm to 205mm. To adjust the fit:
- Unfasten the buckle.
- Slide the strap through the buckle until you find a comfortable and secure fit on your wrist.
- Fasten the buckle securely. Ensure the watch is snug but not overly tight, allowing for proper circulation.

Maintenance
1. Cleaning Your Watch
To maintain the appearance of your watch:
- Wipe the watch case and strap with a soft, damp cloth.
- Avoid using harsh chemicals, solvents, or abrasive cleaners, as these can damage the resin materials and acrylic lens.
- For stubborn dirt on the strap, a mild soap solution can be used, followed by thorough rinsing with clean water and drying.
2. Water Resistance
This watch is water resistant to 50 meters (WR50M). This means it is suitable for short periods of recreational swimming. It is not suitable for diving, snorkeling, or high-impact water sports. Do not press any buttons while the watch is submerged in water, as this can compromise the water resistance seal.

3. Battery Replacement
The watch uses one Lithium metal battery. When the display dims or functions become erratic, it may be time to replace the battery. It is recommended to have battery replacement performed by a qualified watch technician to ensure the water resistance seal is properly maintained.
