I Refer The Honourable Gentleman To The Answer Given Only moments Ago...
Soz, but I got Cheal Watch contact details direct off the Breitling website when I needed a battery and re-pressurisation a few years ago. Again as my previous post...it worked, STILL works, I dive with it very frequently (live and work in the Carib on an island that is in top 10 for quality divesites in the World) and it is STILL sealed and I love it.
Speak to Cheal Watch yourself, ask them whatever questions you need to make a decision whether to use them or not, then as someone else said, once fixed, sell the thing.
I love mine, you obviously do not love yours, so get rid.
