What size are these batteries

Are they long lasting in watches

I’ve come here to order more. Based on my last order date the battery has lasted 20 months

do these fit rotary watches?

Hi these fit many different types of watch.. you will have to open the back or refer to the watch manual to see if they are suitable. I have fitted them into a couple of my wife’s watches and a seiko that I have. They seem to last a good while.

Is this Suitable for Casio g shock watch?

It says online that cr1220 fits some models of casino g shock watches.

Watch ticking now ! at last !

Bought batteries from this seller as thought stocked in UK . but considering time taken to receive same must surely have come from Far East. The batteries eventually arrived and are working well as expected. The seller was very attentive when contacted via Amazon and I am happy with purchase at cost paid .Possibly would buy again in future.
