Blue & White Porcelain Wind Up Vintage Clock

Blue & White Porcelain Wind up clock. Works. Tells time accurately. Not sure how long it lasts once wound, typically they are either day clocks - or 3 or 7 days. I do not know if this is an alarm clock - or if it is, if that portion works - but it keeps good time. No chips or cracks. Vintage. No brand listed. 8" wide x 4.5" tall x 2.5" deep. Weighs 1.4 lbs.
