How to set the time on a Casio PRO TREK series?

　　The Casio PRO TREK series is a professional mountaineering watch. First debuting in 1994, it has now undergone significant evolution from the dial and exterior design to the movement. It is highly popular among sports enthusiasts in the market! So, how do you adjust the time on a Casio PRO TREK series watch? Let me tell you!

　　How to set the time on Casio PRO TREK series

　　To adjust the time on a Casio PRO TREK watch, press and hold the mode button to return to the home time screen, then press and hold the adjust button to enter time adjustment. The first flashing option is the time zone; once entered, you can select your local time zone. If you are concerned that the solar battery is running low, you can place it under sunlight for a few hours!

　　Watch time-setting guide

　　1. Please use and adjust the watch correctly. Before using an automatic mechanical watch for the first time, it must be wound manually, but remember not to overwind it so as to avoid damaging the movement and jamming the mechanism. Take care to gently pull and push the crown when adjusting, without using excessive force. Once adjusted, ensure the crown is pushed fully back in to prevent water resistance failure caused by an unsealed crown!

　　2. All mechanical watches have a bedding-in period. During this period, a daily rate variation of plus or minus one minute within 24 hours is considered normal. Once the bedding-in period has passed and the watch enters a stable phase, a secondary adjustment can be made! The bedding-in period is generally set at three months!

　　3. For multi-functional models, take care not to press the chronograph pushers arbitrarily, and remember not to press them in rapid succession! The chronograph function should not be used when the mainspring is fully wound. The sapphire crystal must not rub against diamonds or other glass surfaces!

　　4. Time-setting method for calendar watches:

　　A. First, pull the crown out to the time-setting position and turn the hands clockwise until the date changes, stopping immediately at this point (which corresponds to 24 midnight). If setting the watch before 12 noon, turn the hour and minute hands clockwise to the required time; if setting after 12 noon, turn the hour and minute hands anti-clockwise to the required time.

　　B. Use the quick-set corrector button to adjust the date and day display to the required date and day of the week.

　　C. The day wheel changeover is permitted to complete within 4 hours after the date changes.

　　D. For single-calendar watches, do not use the quick-set corrector button between 11 pm and 1 am every night. For day-date watches, do not use the quick-set corrector button between 11 pm and 5 am every night.

　　The above is the method for adjusting the time on Casio PRO TREK series watches. We hope this is helpful to you.
