I own Nicolas. Yes the time only is beautiful and considerably rarer than this.
Graham, yes this is the 2105. I've read this idea that there were only twenty made, while I would like to believe it, I have seen no evidence to support it.
Having said that it is a rare watch and I've not seen it in any catalogues or advertisments. Interestingly it doesn't feathure in the big 1969 catalogue I have
which shows just about every chronomatic released.
I don't know the exact date, because this one still has the sale sticker on the back and I can't bring myself to tear it off. Having seen others though it would
appear that 1969 is about right. Several years ago a bunch of these popped up for sale through a US dealer who either bought directly or had access to someone
who bought a lot of NOS Breitlings probably as the company dissolved in the early 1970's. I believe they had about twenty to sell so maybe this is where
the idea came from. When I saw them for sale, I emailed them, then thought about it for a few days. When I called them back they were all gone! Then a friend
of mine in the UK said they had bought three and I was able to buy one from them. Phew.
It is the only version of this large case size that I own and have to say I love it, the only downside is it is NOS. Which makes me scared to wear it too often.
