From memory I think my 1163 has a serial number within the range for the Orange Boy but I can't tell you any more than that.

: I have noticed in the past that quite a number of the early black
: dials, that have lume hour markers, have a tendancy for the
: black of the dial to change to some degree to a chocolate brown.
: In particular i note the 1163 GMT dials have gone this way.
: Now we have discussed previously on the forum that a particlar year
: range of paint used by the dial producer is known to change
: colour. Its also noted in other brands ( i want to say Rolex but
: i cant recall 100% ) at around 1970-71.
: This chocolate effect on the dial could be a good way to try and
: date the dial's production & therefore prove your watch is
: an actual production model as the 11630 Autavia's were not made
: until a couple of years later.
: Anyone have more to offer up on this thought ?

: Cheers - Darren
