I love bright colors, especially color wheels. It is no surprise then that I own (and love!) the first watch included in this post. The Metropolitan Museum Shop has a fabulous collection of colorful watches, including the magic watch (top, $55) and magic twist watch (bottom, $55).
Well I just discovered three more beautiful color watches designed by the company 'Twelve'. For some reason I can't find a website for them, but it looks like you can buy all of these color wheel watches here (in bulk?) for $40. Enjoy!
