Q: what's the batteries for if it's solar power and can I put batteries in
A: Even though it says that batteries are supplied, j4jfit needs no battery since it's solar. Why would you want to install batteries in a solar watch?
submitted byj4jfixit - 2 years agoA: I had this watch for 15 years before I had to replace the battery. the battery is similar to an alternator. And it takes a CR2016 battery. It will literally last the rest of your life.
submitted byinevitable79 - 1 month agoA: The battery that I took out of this watch is a CTL 920 F, Not a CR-2016 like it says in the description. Replacement battery is CTL-920-F
