Breitling Service
I'm with Beagle on this one. I don't use the alarms or noises on mine and I don't use the digital displays continuously either. My first battery lasted 4+ years; I took it into the agent in Peterborough and it came back in a nice padded and zipped nylon case, like a specs case and I think it was under £30 and took 7 to 10 days. Good value for 4 years use I thought.
