Setup
1. Setting the Time and Date
- Pull out the crown: Gently pull the crown (the knob on the side of the watch) to position 2.
- Set the time: Rotate the crown to move the hands clockwise until the desired time is displayed. For models with a date function, ensure the AM/PM is correctly set by observing if the date changes at midnight.
- Set the date (if applicable): If your watch has a date display, pull the crown out to position 1 (halfway). Rotate the crown to adjust the date. Avoid setting the date between 9 PM and 3 AM, as this may interfere with the automatic date change mechanism.
- Push in the crown: Once the time and date are set, push the crown back into position 0 (normal operating position) to start the watch.

2. Adjusting the Silicone Strap
The silicone strap is designed for comfort and durability. To adjust the fit:
- Open the buckle: Unfasten the tang buckle.
- Select a hole: Place the watch on your wrist and choose the hole that provides a snug yet comfortable fit. The watch should not slide freely on your wrist, nor should it feel too tight.
- Secure the buckle: Insert the tang into the selected hole and secure the strap through the keepers.

2. Water Resistance
This watch is water-resistant up to 50 meters (5 ATM). This means it is suitable for short periods of recreational swimming, showering, or washing hands. It is not suitable for diving, snorkeling, or high-impact water sports. Always ensure the crown is fully pushed in before any contact with water.
Maintenance
1. Cleaning Your Watch
- Case and Crystal: Wipe the watch case and mineral crystal with a soft, dry, lint-free cloth. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying.
- Silicone Strap: The silicone strap can be cleaned with mild soap and water. Rinse thoroughly and dry completely before wearing. Avoid harsh chemicals or abrasive materials.
2. Battery Replacement
Your watch is powered by a lithium metal battery. When the watch stops or the hands move erratically, it indicates a low battery. 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 movement.
3. General Care
- Avoid exposing your watch to extreme temperatures, direct sunlight for prolonged periods, or strong magnetic fields.
- Do not operate the crown or pushers while the watch is wet or submerged in water.
- Protect your watch from impacts and drops.
