Shifty Watch

Hey, did that just....nahh, couldn't have been.

This swiss engineered timepiece is perfect for the paranoiac man about town who has achieved everything he ever desired, but who has friends who wish them to maintain an edge of ever-present doubt in their life.

On donning, the watch imprints the owners face into memory. Time is kept through the usual internal mechanism, but the analog hands only move when the gaze of the owner is detected as looking at the watch.

Thusly, any significant lapse existing between one look at the watch and the next, results in a hasty adjustment of the hands so as to display the right time. A movement *just* swift enough to not be definitely registered as having occurred, but not without planting some seed of doubt in the wearer's mind.

       Brilliant!

       Twin brothers will need to have their faces tattooed, so the watches can tell them apart. Maybe with infrared inks so they don't look disfigured to the passing public.

       Would also freak out other people who look at your watch to see what time it is. [+]

       This could also be marketed to quantum physicists who will appreciate a watch on which the correct time only exists while it is being observed.

       Haha [hippo] I'm wondering whether a Heisenbourgois watch that might be attractive to the same demographic, albeit whenever it tells the right time, nobody knows where it might be.

       Indeed - the instructions will need a small disclaimer, along the lines of: "The time-keeping accuracy of this watch has been deliberately reduced in order to make it easier for the owner to find it".

       Great !

       Each hand needs to move at most 179.9°, which hardly counts as "spinning".

       Very nice. [+]

       //Not sure. Hands spinning round the face would be quite noticeable.// Each hand is free-spinning around its axis and has a small piece of ferrous metal at the tip. Around the edge of the watch are a series of tiny electro-magnets. When the wearer looks at the watch a capacitor energizes the correct magnet and the hand spins to that point almost instantly. Capacitor recharged by solar power while the wearer isn't looking.

       Having read all the comments here, I think it is worth pointing out that while it is impossible to know both the exact reading and location of ONE quantum watch, twins need not "have their faces tattooed so the watches can tell them apart". As we all know, when one twin observes his watch, the other twin's watch collapses the probability wave instantaneously: such that he can tell the exact time. Something which would previously not have been able to be determined before the other twin's measurement.

       "Dude, I think your watch is broken."
"Oh, nevermind."

       Well done Papa Tom.
