Hi All,
I am usually pretty good a googling up guesses for watch movements based on sketchy pics but came across an interesting one today that has me stumped. Has anyone seen a complication like this before? It appears the outer ring is the days of the week so I assume it moves too...

The outer scale looks like day of week in French, (Lundi Mardi Mercredi Jeudi Vendredi Samedi Dimanche) then day of the month, hours/minutes, plus the lunar complication (day/night). Can you post movement photo?

my guess is that the day-of-the-week chapter ring is fixed to the outer bezel which is designed to rotate (with the crystal). You set the date and then rotate the day to align, and then you're good to go until next time you need to set the date. This gives you an at-a-glance picture of which dates fall on which day for the present month.
