That watch is weird – I’m Brian Fellow! The TX54 took runner up in the Timex 2154 Future of Time competition. It’s a concept piece billed as “a disposable timepiece that is worn on the user’s thumbnail. While its translucency makes it blend seamlessly with the hand, a selection of text color options and a glow feature that activates on command make it easy to read.” It appears that you use the end of the nail to cycle through options and modes while the time is displayed on the main part of the nail.
It’s kind of a cool idea, no? If it’s supposed to be disposable, too, then it probably wouldn’t cost all that much. Would you buy one?
