Casio Watch F-91W Battery Change (Module 593)
Casio Watch F-91W Battery Change (Module 593) Hello fellow Casio enthusiasts from around the World. I hope you are all well. As the title suggests, I will be replacing the battery on my son's F-91W. He has had the watch from new and it is coming up to 6 years old. It's in excellent condition considering he has owned it since he was only 8 years old and worn it everyday since for school. The display is starting to fade, so it's high time I replaced the battery with a brand new one. The watch uses one CR2016 button cell, which cost me £3.50 (including delivery) for two cells and they are Duracell so a decent battery. I bought two as it's always handy to have new cells in hand if ever required. Now that batteries have been delivered, it's time to get started. I know I should have removed the strap but it simply wouldn't budge from it's position and I didn't want to damage the watch as it is only plastic. I therefore left the strap attached to the watch
