I love the cute "classic" toy robot design of this Japanese watch from Dipiu. And in true Transformers fashion, this is a watch in disguise as, not content with just been worn on the wrist, the little mechanical blighter pops off the wrist-strap so that he (I think it’s male) can sit happily on your desk.
And, if you’re inclined toward wearing timepieces in a more "gentlemanly" fashion, the robo-clock can be attached to a chain as a pocket-watch. That’s sophistication, and all for about £20. The only problem is that you’ll have to figure out how to order one from overseas on Cataloger’s Japanese website.
