Microsoft is working on designs for a touch-enabled watch device, executives at suppliers said, potentially joining rivals like Apple in working on a new class of computing products.

Earlier this year, Microsoft asked suppliers in Asia to ship components for a potential watch-style device, the executives said. One executive said he met with Microsoft's research and development team at the software company's Redmond, Wash., headquarters. But it's unclear whether Microsoft will opt to move ahead with the watch, they said.
