I wonder if it were socially acceptable to wear a watch on every appendage, would I? Well, I'd likely start with one of these vintage 1950s ring watches by LeCoultre and Rolex. Very rare, the platinum and diamond set LeCoultre "Duo-Plan" (pictured right) has an impossibly small dial and movement. It's top-hinged for winding and setting of the watch. Also hard to find, the 18k Rolex Precision (pictured left) has an engine turned conical cover. Now, you can give someone the finger and tell them the time.
