2.2 Initial Time Setting
- Pull the crown (the knob on the side of the watch) out to the first or second click position (refer to specific movement instructions if provided with the watch, as some movements have multiple crown positions for date/time).
- Turn the crown clockwise or counter-clockwise to set the hour and minute hands to the correct time.
- Once the time is set, push the crown back into its normal position to start the watch movement.
2.3 Adjusting the Bracelet
The stainless steel bracelet may require adjustment to fit your wrist comfortably. This typically involves removing or adding links. It is highly recommended to have this adjustment performed by a qualified jeweler or watch technician to prevent damage to the bracelet or watch.

3. Operating Your Watch
3.1 Time Display
Your watch displays time using hour, minute, and second hands. The main dial features clear markers and numerals for easy readability.
3.2 Chronograph Function
The U1258G2 model features a chronograph stopwatch function. This allows you to measure elapsed time independently of the main time display.

- Reset: While the chronograph is stopped, press the bottom pusher (button) located at the 4 o'clock position to reset the chronograph hands to zero.

3.3 Water Resistance
This watch is water resistant to 100 meters (300 feet). This rating means the watch is suitable for recreational swimming and snorkeling, but not for diving. Avoid operating the crown or pushers when the watch is wet or submerged to prevent water ingress.

To maintain the appearance of your watch, wipe it regularly with a soft, dry cloth. For the stainless steel components, a slightly damp cloth can be used, followed by a dry cloth. Avoid using harsh chemicals or abrasive materials.

When not in use, store your watch in a cool, dry place, away from direct sunlight and extreme temperatures. The original watch box provides excellent protection.
