The Breitling Watch Source Forums

Greetings all! Apologies if this has been covered elsewhere, but I couldn't find anything on opening old case backs, only the new 15 sided ones.

I have a Top Time 810 that I am planning on selling, but wanted to open the caseback to take some movement shots. From previous advice I understand it's not a top-loader. I'll most probably take it to someone who knows what he's doing, but on the off-chance that it is in fact pretty straightforward, thought I'd ask here first!

not straightforward, on both case version.
leave it to a pro !

Sounds definitive - thanks for the response WatchFred!
