I have it - it's real.
Movt 46G41 21J.
Calendar - at the beginning of the month - turn lower right crown to line up day of the week with a date and keep it that way for a whole month. Repeat next month, etc.
Sorry - it's easier for me to write in english, but I do understand russian. ;)

Просто и гениально :) Идея заворожила :)

Цена сказочная какая-то :) Еще бы стекло Сапфир (пусть хоть и дороже на сотню) - вообще мечта.

all right, i am understand English,
thanks for the Help,
I guess the principle of the calendar, but was not sure.
