2. Setup and Initial Use
2.1 Setting the Time and Date
- Pull the crown out to position 2: This is the first click. Turn the crown clockwise or counter-clockwise to set the date.
- Pull the crown out to position 3: This is the second click. Turn the crown to adjust the hour and minute hands.
- Push the crown back to position 1: Once the time and date are set, push the crown fully back into its original position to start the watch.
2.2 Adjusting the Watch Strap
The BERNY 2166M watch features a metal mesh strap that can be adjusted by removing links to achieve a comfortable fit. Tools are typically provided for this process.
General Steps for Strap Adjustment:
- Identify removable links: The strap has specific links designed for removal, usually indicated by small screws or pins.
- Use the provided tool (Link Screw Retainer and Screwdriver): Place the strap in the retainer tool. Use the screwdriver to loosen and remove the screws/pins from the links you wish to remove.
- Remove the desired number of links: Carefully detach the links. It is recommended to remove an equal number of links from both sides of the clasp for balanced wear.
- Reassemble the strap: Reinsert the pins/screws to connect the remaining links and secure the strap. Ensure all connections are tight.

3. Operating the Watch
Your BERNY 2166M watch is powered by a reliable Japanese quartz movement, ensuring accurate timekeeping. The date window automatically advances daily. If the date needs manual adjustment (e.g., after a month with fewer than 31 days), follow the date setting instructions in Section 2.1.
4. Maintenance and Care
4.1 Water Resistance
This watch is 3ATM (100ft) water resistant. This means it is suitable for daily use and can withstand splashes, rain, and hand-washing. NOTE: Do not wear the watch in the shower, sauna, or while swimming. Avoid pressing any buttons or adjusting the crown while the watch is submerged in water, as this can compromise the water resistance.
4.2 Cleaning
To maintain the appearance of your watch, wipe the case and strap with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials that could damage the finish. For the metal strap, a soft brush can be used to gently clean between the links.
4.3 Battery Replacement
The watch uses 1 Lithium Polymer battery (included). When the watch stops running, it indicates that the battery needs to be replaced. Battery replacement should be performed by a qualified watch technician to ensure proper sealing and maintain water resistance.
5. Troubleshooting
- Watch not running: Ensure the crown is fully pushed in (position 1). If it still does not run, the battery may need replacement.
- Incorrect time/date: Follow the instructions in Section 2.1 to reset the time and date.
- Condensation under the crystal: This may indicate a breach in water resistance. Avoid further contact with water and seek professional service immediately.
