Apple (AAPL 0.13%) is likely just months away from taking the wraps off of its expected iWatch. The Mac maker could easily sell tens of millions of units of its smartwatch, which represents a significant opportunity for any component suppliers lucky enough to win a spot. Looking at recent Apple devices, investors can speculate on companies that Apple may tap as vendors. Possible names include NXP Semiconductor (NXPI 5.02%), Universal Display (OLED 0.72%), STMicroelectronics (STM 3.23%), and OMRON Global.
