3. Setup Guide
3.1 Initial Charge
Before initial use, expose the watch dial to a bright light source (natural sunlight is ideal) for several hours to ensure a full charge. The power reserve indicator will show the current charge level. A full charge can last for several months in darkness.
3.2 Setting Time Zone and Atomic Time Synchronization
The PCAT watch is radio-controlled and designed to automatically synchronize with atomic time signals. Upon receiving the watch, it may be necessary to manually set your home time zone to ensure correct time and date display. The watch will then automatically adjust for Daylight Saving Time and maintain precise timekeeping.
Refer to the detailed instructions in the full user manual for specific steps on how to manually set the time zone and initiate a manual radio signal reception if needed. This process typically involves pulling out the crown and using the pushers to select your desired time zone, after which the watch will attempt to receive the atomic signal.

4. Operating Instructions
4.1 Chronograph Function
To use the chronograph, press the upper right pusher to start and stop the stopwatch. Press the lower right pusher to reset the chronograph hands to zero. The chronograph measures elapsed time up to 60 minutes in 1-second increments.
4.2 Perpetual Calendar
The perpetual calendar automatically adjusts the date for months with 30 or 31 days, and also accounts for leap years. Once the watch is correctly set to your time zone and synchronized with the atomic time signal, the date will always be accurate without manual adjustment until the year 2100.
4.3 Dual Time and Alarm
The watch supports dual time zone display, allowing you to easily switch between your home time and a second time zone. An integrated alarm function can be set for daily reminders. Consult the full manual for detailed instructions on setting and utilizing these advanced features.
5. Care and Maintenance
5.1 Cleaning
Wipe the watch regularly with a soft, dry cloth to remove dust and smudges. For the stainless steel bracelet, a mild soap solution and a soft brush can be used, followed by thorough rinsing and drying. Ensure the crown is pushed in before cleaning with water.
5.2 Water Resistance
This watch is water resistant up to 20 bar (200 meters). This rating makes it suitable for showering, swimming, and snorkeling. However, it is not recommended for scuba diving. Always ensure the crown is fully pushed in before exposing the watch to water.
5.3 Charging and Storage
To maintain optimal performance, ensure the watch is regularly exposed to light. Avoid prolonged storage in dark places, as this can deplete the power reserve. If storing for an extended period, place it in an area where it can receive ambient light.
