Disney Tinker Bell "Sunray" watch, likely from the late 1990s or early 2000s.

Manufacturer: The back casing indicates it was made by SII (Seiko Instruments Inc.) for SI Marketing International, Inc. SII is a reputable subsidiary of Seiko, meaning the internal movement is likely quite reliable for a character watch. ​Model Number: MC0082.
