Watch Battery.
Good price and works very well. Item arrived as ordered and even was in my hands a couple of days earlier than suggested. It’s very easy to change a watch battery and the saving of approx £8-£10 is well worth the postal wait.

Has lasted longer than my original watch battery so seems to have good quality and for a fraction of the price. It’s a win win

Bought as it was available on prime in a low quantity
I know it's cheaper to get larger multipacks. I really only wanted/needed one battery. But as there's only two I'd happily pay more. Tbh id probably pay a similar amount for just one as this was the only one battery of this size on prime that didn't come in a multipack. Value for money I feel was great for a prime item in low volume and I used it to replace my swatch battery. Which was disappointingly a lot simpler than I thought, as I'd been putting it off for literally years! After watching a quick YouTube tutorial I found what looked like it COULD be a complicated/trip to cobblers watch change is very simple and the size is clearly printed on the search watch battery which is easy to pop out and reveal Renata seems to be the watch battery gold standard, after a bit of googling, watch keeps time perfectly and have had it in for a few months so can't say there's any issues with power or longevity 🤷🏾♀️ I hate having to buy multi packs on prime and carting around for years. So this suited me just great!

Amazing and original product, worth buying from Amazon as if you go to a watchman shop, they charge you almost double the price paid at amazon.
S**.
Entgegen der Bestellung, die für zwei Batterien erfolgt und bezahlt war, lag dem Briefumschlag nur eine Batterie bei. Das Angebot ist irreführend.
