Hi Roff,
Well spotted. Sorry, I was not trying to say mine was a 1969 model.

You are correct, the O & W version is much later. I understand that Albert Wajs bought up the rights & stock for the 806 & 809 from Breitling in 1978, or there abouts. He was releasing about 300 a year of his own Aviation versions in either 12 hour or 24 hour formats and some in 18k gold. I can’t tell (don’t know more likely) how much of my version is original stock components and how much was manufactured more recently. I beieve he also bought the manufacturing base for the two watches as well. I bought this one in 2007 from the Australian agent, and was absolutely delighted when I opened the box. Although in stainless, there is a definite feel of something a bit special about it.
The movement has caused a bit of comment with watchmakers I know, here in Australia. It’s not one used by Breitling, I think, and it’s not seen that regularly here, or so I am told. As always, I will stand corrected if that is not the case. In your extensive knowledge, do you know of any other watches that use the 7736/24? I'd be interested in knowing that, as I remain curious.
Jim
