In the end, I believe that it's fairly simple: white bezel with white dial; blue with blue; black with black. and, of course, the gold with the goldish / beige-ish / whatever-it-is.

yes -- there were two styles of markers, but still, color of bezel should match color of dial.

: My opinion, just from the catalogs and what I
: have seen over the years: there were two
: styles of cal 12 Montreals, one style with
: raised hour markers and one with just
: luminous strips for hour markers.

: The hard info for me comes from Page 20 in the
: 1974 catalog (below) shows these two
: variations, and they seem to both come in
: blue and black, with the raised marker
: version coming in white as well. There was
: also definately a gold raised hour marker
: version (in fact I bought one on ebay about
: 2 minutes ago).

: So for me there was: 110.503 BC blue dial, blue
: inner bezel ring, blue subreg, flat markers
: 110.503 NC black dial, black inner bezel ring,
: black subreg, flat markers
: 110.503 B blue dial, blue inner bezel, white
: subreg and seconds track, raised markers
: 110.503 N black dial, black inner bezel, white
: subreg and seconds track, raised markers
: 110.503 W white dial, white inner bezel, black
: subreg and seconds track, raised markers
: 110.503 ? gold dial, gold-ish yellow/beige
: inner bezel, gold subreg and seconds track,
: raised markers

: then there is the black dialed PVD version like
: 110.503 NC, and the later 7750 movement (?)
: versions (different story).

: I don't believe there where mixed inner bezel
: /dial colour combos like blue dial, white
: inner bezel...but I have no way of proving
: it, except that it looks "wrong"
: and is not documented anywhere.
