There are many cool smartwatches on the market. The Tesla Watch is not a smartwatch, but it does look quite intriguing. It has 2 light-up vacuum tube-style LEDs on top and an on/off switch to control red LEDs in vacuum tubes. You get a 304 stainless steel case, glass face, and leather strap.
The Tesla Watch is not water resistant, but it does look quite fun to wear. You can find it on Think Geek.
