When you're rolling with 50 Cent's G-Unit, you'd better be sporting only the hottest gear on the market. Like, say, a watch that doubles as an MP3 player. 50's line of G-Unit Watches feature everything from spinning bezels and iced-out faces to the world's first MP3-playing watch — available in 256 or 512 megabytes of storage (that's eight and 16 hours of music, respectively). The G-Unit line of timepieces will range in price from $299 to $3,500 and will be in stores nationwide next month.
