The Tesla Watch goes with your steampunk aesthetic. With a weathered-brass look on all the metal parts, this analog watch features a leather strap. The highlights of this design, however, are the two faux vacuum tubes with red LEDs inside that you can turn on and off with the flick of a switch. Everybody will want to ask you what time it is so they can see your watch. Just remember to follow the answer with, "... 1875."
