Here is one I have an ELOGA with a Fontmelon caliber 175. These should all have the same movement, just a different name on the dial, etc.
Top crown in changes the month, out rotates the outer date disk. Date pointer arrow changes with the hands no quick-set.
Value probably not more than about $200-$250 for an nice one, the "maker" really isn't a factor in value since the movements were all the same anyway.
An interesting complication for not a lot of money.
