I've just removed the bracelet (serial number shall be sent in an email) , the bracelet is stamped 4 over 70 . Further observations of this watch show that the case is marked with a single triangle stamped in the back of the lower left lug (as seen when the watch is dial faced down). As i have seen with these triagle stamped cases before the end pieces are much harder to remove/reset, it could well be that the holes for the springbar are slightly differently placed than on other 1163 cases. My final observation is that just as in the original Cal.11 movements the date change takes place over 15 minutes, starting at quarter to the hour.

Thanks - Darren

: Nice new addition . . . I know that you will enjoy wearing this
: one.

: This is one of my first Heuers, and still one of my all-time
: favorites . . . there's something about the lume, the hands and
: the Pepsi colors . . . they all work together, very well. The
: next execution added the distinctive red-edged hands, but I am
: also liking the brushed steel version.

: Please let me know if you might be able to provide serial number
: and perhaps a date from the bracelet.

: I'm very proud to presenent my latest arrival. A very rare early
: 1163 GMT Autavia with 1-24 bezel and modified Cal.11 movement
: instead of the regular Cal.14 normally in place with other
: automatic Autavia's. The GMT Autavia's are quite striking with
: their 'Pepsi' bezels and this 1-24 example is in almost perfect
: shape, rich in colour without any sign of the fade often
: associated with aged/used examples (my guess is long term
: exposure to UV rays form sunlight causes the pigment to fade).

: This watch is in stunninly good condition, its blend of colour from
: dial/bezel/hands has me checking my wrist again and again.

: I must excuse myself for the average quality photo's as i have only
: had success previously taking photo's with a natural souce of
: light. Sadly, there is currently very little sunlight up here in
: Scandinavia so i have had to experiment (with only limited
: success) with lighting. I promise to read Paul's photo tutorial
: and put some of his lessons to work in the future.

: My greatest thanks go out to Javier for this fantastic watch,
: another fantastic trade from a really helpful guy (forum readers
: may remember my awesome Cal.11 Siffert) - Cheers mate

: Here is my new baby - enjoy
