Citizen Promaster Sky RC - Silver - 41mm

The watch is designed to attempt synchronization automatically at preset times, typically overnight. You can also initiate a manual sync if needed.

It means the watch automatically receives time signals from atomic clocks via radio waves, ensuring extremely high accuracy without manual adjustment.

With a full charge and in normal use, the watch can operate for several months to over a year in power-saving mode without light exposure, depending on features used.

The watch has a water resistance of 200 meters, making it suitable for surface swimming and recreational diving, but not for professional saturation diving.

The strap is made of high-quality silver stainless steel, measuring 21 cm in length and 21 mm in width, with a fold-over clasp with a push-button release.

The watch comes with a standard 2-year warranty against manufacturing defects.

World time settings are adjusted through specific crown and button operations. Refer to the user manual for detailed instructions on selecting and displaying different city times.

Ensure the watch is placed near a window, away from electronic devices. Try manually initiating the reception process as per the user manual. Check if you are within the watch's signal reception range for your region.

The watch may require charging. Expose it to a sufficient light source. If the issue persists after charging, a manual reset or professional inspection may be needed.

Verify that the correct time zone is selected. Attempt a manual radio reception to synchronize with the atomic clock. Ensure the watch is not in a mode where manual adjustment is locked.

The luminous material needs to be 'charged' by exposure to light. Expose the watch to a bright light source for a few minutes for maximum glow.
