Samsung said to be on watch

The S. Korean electronics giant, which is locked in a smartphone war with Apple (AAPL), could also challenge the U.S. tech giant for space on consumers' wrists. A source told Reuters that Samsung is working on a digital device that could be worn like a wristwatch, and perform many of the tasks of a smartphone. Apple has long been rumored to be working on some sort of iWatch product as smartphone sales growth slows. Apple shares fell 0.3% to 454.49.
