Cinnamoroll (series)

Official Sanrio character artwork of Cinnamoroll, used here to represent the character generally, as neither Seiko's nor Sanrio's own announcements name a single anime or series.

Cinnamoroll is a Sanrio character created in 2001 with designs by Miyuki Okumura: a white puppy with a tail that curls like a cinnamon roll, long ears he can use to fly, and blue eyes. He has starred in his own manga, an anime film, and animation shorts. (Wikipedia) Seiko's collaboration watches, sold through its PREMICO character-watch imprint, credit both releases to Cinnamoroll generally rather than to any single work.
