3.2. Adjusting the Watch Band
The stainless steel bracelet band has a width of 22mm. Links can be removed or added by a professional jeweler to achieve a customized fit for your wrist. This ensures comfort and prevents excessive movement of the watch.
3.3. Setting Time and Date
- Time Setting: Pull the crown (the knob on the side of the watch) out to the outermost position. Rotate the crown to set the hour and minute hands to the correct time. Push the crown back in to the normal position to start timekeeping.
- Date Setting: Pull the crown out to the middle position. 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 the crown back in to the normal position.
4. Operating the Chronograph Function
The chronograph feature allows for precise timing of events. Your watch includes three subdials for this purpose.

5. Water Resistance
This watch is water resistant up to 100 meters (330 feet), or 10 ATM. This means it can be worn during bathing, swimming, snorkeling, and shallow diving. It is not suitable for high-impact water sports or deep-sea diving.
- Do not operate the crown or pushers while the watch is wet or submerged in water.
- After exposure to saltwater, rinse the watch with fresh water and dry it thoroughly.
6. Maintenance and Care
6.1. Cleaning
To maintain the appearance of your watch, regularly wipe the case and bracelet with a soft, damp cloth. For deeper cleaning, a soft brush (like a toothbrush) with mild soap and water can be used, especially for the bracelet. Ensure the watch is thoroughly dried afterward.
6.2. Battery Replacement
The watch is powered by 1 Lithium Metal battery (included). When the watch stops running, it indicates that the battery needs to be replaced. It is recommended to have the battery replaced by a qualified jeweler or watch repair specialist to ensure the water resistance seal is maintained.
6.3. General Care

- Protect the watch from impacts and drops.
- Store the watch in a dry, safe place when not in use.
