This Alain Silberstein watch is a very rare and special piece. The movement is very complicated, featuring chronograph, full calendar, moonphase, and day/night indicator. The day of the week is demonstrated by the smiley face, Monday starts off with a Frown Face, and as the week progresses the face becomes happier. The original warranty certificate is not included, this is number 133/999. This watch is in stock and ready to ship immediately!
