Genuine battery good price
Battery arrived earlier than expected and appears to be genuine Renata brand. Voltage checked to be 1.6 so is fully charged and the date code is for 2026 so it’s reasonably fresh. Watch is now working ok so hopefully this will last a couple of years or more although they are tiny batteries compared with some others.
