Once I think I've seen everything, somebody alerts me a mind-blowing gadget like this Steineck Subminiature Wrist-camera. Thanks to Max Busser, founder of MB&F Horological Machines who shared his find (right) from a vintage watch store in Lugano, Switzerland. Needless to say, I've been obsessed these antique spy/detective/novelty gadgets for the last few days and have uncovered a secret force of "Submini" wrist-cameras. A wide array of styles existed over many different eras, originating in 1907 with a pocket watch camera. Others were fit into rings, some were undisguised miniature cameras fit onto a wristband but my favorite remains the Steineck, with its robotic cyclops face and potential for Captain Kirkian prop-weaponry.
