Since there doesn't seem to be a comprehensive list with Breitling 765 models that were released over the years I decided to make one.
This is the list as I consider 'correct' , and as always things will change as I see or notice more differences or dates that need to change. The early history of these pieces I investigated here viewtopic.php?f=11&t=50565
1953
1953 , the birth of the 'Original' 765 AVI
1955
Around 1955 we see 2 models.
1 with a 'digital' date aperture minute counter
and 1 with a normal subdial layout
I believe that the approx number of AVI watches made, Analog and Digital combined, between 1953 & 1958 is 1000 pcs. This number is based on the serial numbers I collected
1960
still 2 models like above with the only change being the larger beads on the bezel and 'fatter' hands on both models
and the 'normal' dial layout with subdial but also 'fatter' hands and larger beads on the bezel
1962 / 63 / 64
Somewhere between 1962 and 1964 Breitling changed from an all black dial to a 'reverse' panda dial. I have seen indisputable examples with a '62 case number both in all black . and the earliest 'reverse panda' I know of also has a '62 case number . note that the 1962 / 63 / 64 765 AVI has a steel bezel
1965
1965 marked a significant change in this family of watches . The Bezel is changed from steel to anodized aluminium And the model designation changed from 'AVI' to 'CP'. The CP stands for Co-Pilot (The Raquel Welsh watch is actually a AVI , not a Co-pilot)
there was also a model with a slight variation in the bezel
1966
In addition to the 'normal' CP with black anodized bezel a 'Yachting' model with a 15 minute countdown subdial and bezel was added to the lineup , both models were sold concurrently
1967
The yachting (765 CP) model received a newly designed handset
1969
Between 1967 and 1969 Breitling stoppedr using a separate name for these on the case and they only had a reference number . So we say goodbye to the Co-Pilot name as well. An extended family we have now . the 7650 , larger than the previous 765
a newly designed yachting model 7650
and we even see a 24 hour model the 1765 Unitime
approx number of 1765 watches made, is 1000 pcs. This number is based on the serial numbers I collected , runs from 1276000 to 1276999. However a batch of these cases was used to make 'TopTime' versions . 12 hour watches with the V7736 and V178 movement . These watches were given the reference 1765/36 when equipped with the 7736 movement or left with 1765 if they have the V178 movement . 1765 Toptimes typically have a serial number in the 1276300 - 1276399 range but have been seen with serial numbers in the 12768xx range as well
When these TopTimes were made is currenty not known but I assume the 1765 Unitime was not a 'bestseller' and they used part of the cases to build the 1765/36 before (or concurrent) with the release of the 7656 as the dial and hands are Identical to the 7656
Also somewhere in 1969 a separate ref number was given to the yachting model
the ref 7660
<insert big cased watches here
>1975
For a few years it was very quiet on the 765X and X765 front. Until in 1975 Breitling released the 7656 'Top Time'
