I have never seen a Monaco with indication of days of the week. We do, however, see this on some fakes, often made in China.
We can be more certain if you can send or post photos, but I am confident that this one was not made by TAG-Heuer.

: Hi, I am trying to figure out if the Tag Heuer Monaco automatic
: watch (silver metal) my mom recently gave me is authenic. It's a
: beautiful watch, but I cannot find one that is identical to it
: in my searches. The back of the watch has a window where you can
: see the inner-workings of the watch, including a moving part
: with the Tag Heuer logo design on it. The back of the watch has
: the following letters/numbers: MV 045198, 3ATM Water, and
: automatic at the top. The square blue face has a darker blue
: cut-out border and a lighter blue checker-board pattern. The cut
: of the boarder inside of the watch face is identical to other
: designs, but the lighter blue checker board pattern is unique,
: as far as I've seen. Another unique characteristic is the
: weekdays on one of the registers; the other two have numbers. It
: reads Monaco Heuer inside the face of the watch. It glows in the
: dark very nicely after being put under a light bulb for a few
: seconds. It has three buttons on the side and the button in the
: middle has the Tag Heuer logo on it. The band has been
: altered--it is a blue leather band with a watch clasp added to
: it, and you can still see three holes in the leather band, so it
: looks kind of odd. The watch clasp that has been added to the
: leather band reads Monaco 1969 and Swiss Made. Can anyone tell
: me if this is an authentic Tag Heuer watch? The white dials look
: to be in perfect condition; in fact the watch minus the band
: looks to be in mint condition. I appreciate your time and help!
: Thanks, Chere'
