Perfect replacement
Did the job perfectly. Had a watch with a dead battery, saw these and thought they looked good. Fit the watch fine and easily replaced the old battery so all up and running again. Not expensive and what I needed. Cannot comment on battery life - only time will tell (no pun intended!) but if it comes close to the original I will be pleased.

Happy with my purchase
Well, it's a watch battery - I chose this because it was just two batteries and didn't want/need a pack of 8 or more which seemed to be what most retailers were selling - main thing is the battery is the right type and works - the cost was £2.95 (No extra charge for delivery as had already paid for Amazon Prime for another delivery) - pleased as I was quoted c.£20 by a chain to fit a new battery with a lifetime guarantee (free replacements)

Trusted make of watch batteries
I’ve bought from these before and they are great. Unfortunately someone was having a bad day and I ended up with a 371. It’ll come in for something and I would still use them again.
