As a big TI fan (I love hacking on the MSP430, Stellaris, BeagleBone, etc), the Chronos would be great if it weren't so incredibly 1970s/early 1980s dorky looking. I mean, I'm not particularly fashion conscious, but I wouldn't wear that thing.
Without Bluetooth support, it's not much use. You'd be limited to having a dongle connected your smartphone, or the watch only working when you were within the range of a base station.
