thanks for your help.
Please contact wholesaleoutlet990@yahoo.com. You can also find something under their website http://www.ewatchparts.com/.
They make a lot of aftermarket parts and also new bezels and inserts for a lot of brands.

Kind regards

: HI Harry i also have a Autavia GMT 2446c the watch i have is at
: mint level,would be NOS if not for the medium fade on the bezel,
: mine came with a GF bracelet box instructions and all paper
: work,mine is a 1969 watch but paperwork is dated 1972,i think my
: watch must have been sitting in a shop window for a number of
: years picking up ultra violet rays which would have faded the
: bezel because as i said watch in NOS except for bezel... the
: good news is i have your sizes you request.The outer size of the
: bezel is 40.67 ......... the inner size is 32.95
: These sizes were taken with the bezel removed from the watch and
: are the correct steel bezel size not a bezel insert size because
: the 2446c did not have a bezel insert.The sizes were taken with
: a calibrated Mitutoyo digimatic caliper.
: IF you have a contact who is going to produce a bezel for you or
: you have a genral idear how to overcome the faded bezel problem
: i would like to help and work with you on this problem as im a
: mech engineer and could help to point you in the right
: direction.All us 2446c owners not the hunt for a mint or NOS
: bezel is like looking for the lost ARC..
: Let me know how you get on??
