I now do watch battery changes on a fairly frequent, regular basis. The variety of watch and battery types is legion and some are out-and-out pigs to deal with. I have no experience of the Breitling as such but after a couple of horror stories with Omegas and other up-market varieties, we now send them to our workshop to be done (at greater cost) rather than in the shop. One make, in particular, requires two internal contacts to be shorted out after battery change to re-start the mechanism!!
We are just starting to get supplies of one of the best bits of horological engineering I have come across - ceramic case and bracelet, solar powered with six months power reserve, and radio-controlled - accurate to half a second in a million years - £500 GBP a copy and I WANT ONE. Sold our first two within days of them arriving. Drool, drool, drool.....
