I purchased one of these perpetual calendars off of eBay a couple of years ago (thank you, dedalo1972). I knew nothing about it and couldn’t find anything either, that is until recently.
Called Magical, the calendar operates with a simple twist of the wrist. Inverting the small plastic container, by rotating the top downward, advances the day. At the end of the month there is a final tile that reads 30/31, after which comes 1.
Each side of the calendar has a circular opening 2.9cm in diameter, through which the date shows. The calendar is small, at 9.7cm tall, 5cm wide, and 2.9cm deep.

The only marking on the Magical perpetual calendar is a small “made in Italy” imprint on one side, just below the opening that reveals the date. It is on the side that reveals odd numbered dates.
