Yes, but not smaller than a Ladies ring. Rings embedded with tiny watch mechanisms have been around for some time, but I don't know when they first came out. Probably after 1929. Here is one from the fifties. http://watchismo.blogspot.com/2007/01/giving-you-finger-rolex-jaeger.html They are rare and expensive. They must have been a pain to wind... probably had a separate tiny key for winding. The Jaeger-LeCoultre '101' watch movement was introduced in 1929 and claims to be the smallest mechanical movement ever made, but there could have been others in the 1930s, that were nearly as small - despite the great depression. It weighs about one gram including the hands and dial. The very wealthy did not stop buying extravagant novelties just because of a silly depression (nor traveling with a large entourage to China to find Ming vases, which were all the rage.)
