A diy job if researched properly and you have basic watch repair tools.
Watch battery replacement. An easy battery swap on a Bering watch. The proceedure is easily researched online and a basic tool kit enabled me to carry out the job at home. The back was a snap off type which was easily removed and refitted after changing the battery. Caution though I have come across some watch backs that have prove difficult to press fit.

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.
