We’ve seen all sorts of high-tech wristwatches before, but there are some retro watches that always seem interesting. The Seiko Frequency is one of those cool watches that would belong somewhere in your collection of cool stuff. It has a built-in speaker and sports 6 drum patterns created specifically for the watch by Tetsuya Komuro, one of the most successful and influential pop songwriters and producers in Japan. It also features a chronograph, alarm, calendar, 2 metronome modes, and a BPM counter. You won’t be able to find these at your local stores anymore, but there are a couple of them on eBay going for about $350 odd. Would you shell out this kind of money for a nostalgic watch, or would you go for some new gadget wizardry?
