I've been watchless for a while now, but recently got myself a watch made by the Slava factory in the USSR sometime in the 50s. It needs wound every day, goes a few minutes out of time each week but I don't care too much as I wind and set it to the school clock each morning.
Oh and Wez I had a binary watch, students are constantly perplexed by it. Not having a proper face or hands, only a circuit board and LEDs confuses the hell out of kids.
