1930's Rolex golf watch

[springer]

I was in an antique mart today that had a jewelery/watch shop in the back of the mart that had many interesting and vintage watches for sale. I found an old Rolex there that was quite unique. The shop owner called it the "golf" Rolex. The watch was enclosed in a sterling silver case that had a convex flip-top that looked like the skin of a golf ball. When the top was opened, inside was a manual wind Rolex. The watch also flipped out of the case so the watch could be wound. The watch alone appeared to be around 25mm in diameter and still wore the original Rolex dial and hands. Needless to say, I found it quite interesting.

Has anyone ever seen one of these "golf" Rolex watches?

If there is enough interest, maybe I can get back there and obtain a photo of the watch.
