I really like Tokyoflash. They sell unique wristwatches with lots of LEDs and bling (and sometimes dubious quality) that are real headturners. I got myself a golden Pimpin Aint Easy a few years ago and I’m thinking of buying the Denshoku.
What’s nice is that Tokyoflash has started selling other accessories and designware also, like wallets, clocks, USB drives etcetera. Be sure to check it.
If you’re a LED watch buff, Coolwatch might also interest you.
