Lanny - by co-incidence I was just doing some research on the Mareographe & remembered Noodia had one.. here is one of Noodia's excellent pics.. the bezel looks black edged..

: I recently purchased on Ebay, a specific lot of materials from a
: watchmakers shop liquidation - what seems to be a box of
: 2446Autavia parts - included in it were a few signed crowns,
: stems, couple sets of pushers, some cal 11/12 parts 3 sets of
: replacement crystals and an NOS Autavia 2446 tachy bezel - the
: first thing i noticed about the bezel (which is what drew me to
: bid on the auction in the first place) is that the side of the
: bezel is 100% black with NO signs of the steel that is
: underneath, - now i know that its possible b/c i have a couple
: 2446's and they each have bezels that are predominantly steel
: but have some traces of a black finish inside the grooves. I was
: wondering if anyone had any pictures of an NOS 2446 bezel - or
: if any one has seem an all black bezel - i will take some
: photo's and post.
