After looking for a replacment battery for my watch, I came across this one.
69p including postage, I was wondering if it was OK??.
Check reviews, seem most were good so took a chance.
It came in a letter taped to the invoice.
The battery is in a blister pack, it has swiss made engraved on it with the name Renata.
Unscrewed the back of my watch and replaced battery.
The watch is working, so the battery is fine, how long it will last I don't know
I will update if it fails. The original one lasted over 2 years.
