In this video, I show how to disassemble your Casio PRO TREK PRW-3510 (and similar models like PRW-35Y), replace the battery and watch band, and perform a full maintenance session.
What you’ll learn:
– How to open the watch and remove components
– Replacing the CTL1616F battery
– Lubricating the o-ring for better water resistance
– Cleaning the watch case and buttons
– Fixing the "ERR" / "SENSOR ERR" error message
– Performing a hard reset if the watch won’t start properly
Works for many Casio Protrek models using similar module layout.
