Our 13-inch Christmas Wall Clock features a whimsical dial illustration of Santa trading in his trusted Sled and Reindeer for a Train to deliver presents this holiday season! To add ambiance to the occasion, each hour is announced by one of twelve traditional Christmas carols getting everyone in the spirit. In addition, the festive Santa Train Clock's green frame enhances any holiday decorations. A Light sensor deactivates the carols when the room is dark.
