A vintage mechanical birthday calendar charm in goldtone. This charm is from the 1960's to 1970's. It's large at 1 1/4 inch in diameter. Two tiny metal tabs at the bottom allow you to select the month and day that appear in the little window, so it can be personalized to your own birth date. A clasp at the top allows the charm to be easily attached to your bracelet or necklace.
Condition is excellent.
