I have been very busy lately and unable to get to my safety box to collect this watch and take more detailed photo's so i'm afraid you will have to make do with the photo's i already had on file.
From the previous thread about the 1163P Diver a couple of days ago it was Shaun's (2 truths and 1 lie) post that was most relative to this watch.
I too had seen the 1972 calalog photo of the 1163P diver with this decompression bezel in place but also noted that my watch has the Orangeboy style steel baton hour markers where the catalog version has the full lume applied markers.
I'm left with more questions than answers in this case.

- What do people think - was the applied lume version from the catalog produced?
- Did they use the Orangeboy version dial i have instead when it came to production?
- Any other theories ?
- I'd really like to see any others out there, does anyone have one to show. Can you show the same decomp bezel i have in place?
- Is the bezel simply an option, such as the deci-version, which customers could order for their Autavia?

I replied the other day saying that i think of my watch as an Orangeboy with a decomp bezel in place, hopefully with a little feedback from the forum we can help clear this mystery up.
Cheers - Darren
