The only difference is printed on the dial.

: Hello all,

: I am very lucky to have just found a beautiful "closet
: find" of one owner Heuer Autavia 2446C Abercormbie &
: Fitch model that has literally been sitting in a box on a shelf
: for the past 30 years since the owner wore it. Dial is perfect
: and all original lume fully intact and crystal in excellent
: shape, case shows use but all edges on lugs sharp, never
: polished and serial and model visible between lugs. Has the
: first execution snap back case and round pushers. Just a beauty.
: I'm very excited about it, but my question is whether there is
: any difference other than the Abercrombie & Fitch text
: wrapping around 12 hour subdial? looks just like a regular 2446C
: otherwise. Will post photos soon.
