Good Battery
Renata batteries are great quality, last a while and just do a great job! I always purchase this make. What else can I say??

Great value and very speedy delivery
Received the next day after ordering and was able to fit it in my watch and get it going again in just minutes. Much cheaper option than going to the jewellers and paying them an awful lot more to do exactly the same.

good watch battery
Good battery, arrived promptly. Bit slim (shallow) compared to the battery in my watch of same code, but it fits, it works, and even better it's a bargain compared to Jewellers.

Top (so far) battery
It's a battery. It arrived. I put it in. Watch now works. Time (literally) will tell how long it's been sitting on a shelf. No complaints so far.

These are Swiss made batteries of good quality. Excellent value too. A local market trader was asking £4 each for the same battery.

Batteries
I had a watch where the hands didn't go round. I bought this battery and put it in. Now the hands go round. What more can you want? More time in the day? Tough, that ain't never gonna happen.

Can't go wrong at this price!
Bought this to replace the battery in my Seiko, worked straight away - can't go wrong with the price, even if it were to last a year only.
