Idle Stop
I took my watch into Breitling's UK office in central London. They sent it to the Service department at TW, and it was returned direct to me.
I assume Goldsmiths are agents; there's a list of authorised retailers on the
Breitling website.
I've got the Aerospace - the original, not the latest model (which I don't like as much). The low battery warning flashed and, after a few days, the watch stopped. I didn't notice any inaccuracy during that period.
