2 X Renata Battery 399 SR927W SILVER 1.55V SWISS MADE

Great, fitted straight into watch.

Bought to change my own watch batteries. Saves money and you don't need to take your watch to a jewellers.

Good batteries

Works fine, and I have a spare

Good battery

I ordered four of these unfortunately only two held a full charge.

If one can change the batteries on should go for these excellent batteries
