Setup
1. Setting the Time
- Pull the crown (located on the right side of the watch case) out to position 2.
- Rotate the crown clockwise or counter-clockwise to set the hour and minute hands to the desired time.
- Push the crown back into position 1 to start the watch.
2. Adjusting the Bracelet
The stainless steel bracelet is designed for a comfortable fit. If adjustment is needed, it is recommended to visit a professional jeweler or watch repair service. They can add or remove links to ensure the watch fits securely on your wrist.
Operating the Chronograph
Your Fossil FS4359 watch features a chronograph function for measuring elapsed time.
1. Starting and Stopping the Chronograph
- Press the upper pusher (button) to start the chronograph. The chronograph second hand will begin to move.
- Press the upper pusher again to stop the chronograph. The elapsed time will be displayed.
2. Resetting the Chronograph
- After stopping the chronograph, press the lower pusher (button) to reset all chronograph hands to their zero positions.
- Note: Do not press the reset pusher while the chronograph is running, as this may cause damage to the movement.
Maintenance
1. Cleaning
Wipe the watch case and bracelet regularly with a soft, dry cloth to remove dust and dirt. For stainless steel, a slightly damp cloth can be used, followed by immediate drying. Avoid using harsh chemicals or abrasive materials.
2. Water Resistance
This watch has a water resistance rating of 50 meters (5 ATM). This means it is suitable for short periods of recreational swimming, but not for diving or snorkeling. Avoid operating the crown or pushers when the watch is wet or submerged, as this can compromise the water resistance.
3. Battery Replacement
The watch is powered by a quartz movement and requires a battery. When the battery runs low, the watch may stop or the second hand may skip. Battery replacement should be performed by a qualified watch technician to ensure proper sealing and maintain water resistance.
4. Storage
When not wearing your watch, store it in a cool, dry place away from direct sunlight and extreme temperatures. Keep it away from magnetic fields, which can affect the accuracy of quartz movements.
Troubleshooting
- Watch not running: Check if the crown is pushed in completely to position 1. If the watch still does not run, the battery may need replacement.
- Incorrect time: Reset the time as described in the 'Setting the Time' section. If the time continues to be inaccurate, the watch may require servicing.
- Chronograph hands not resetting to zero: If the chronograph hands do not return to their 12 o'clock position after resetting, they may need calibration. Consult a professional watch technician for adjustment.
