This is the first series Mickey Mouse timepiece from the Ingersoll factories in the USA patent 1932! This is a 3 piece case. I cleaned this original case though not polished left in it's original condition as most replate the case though not here! This case is 40mm long and wide less the original crown it is 34mm. The crystal I believe is original and I buffed it till 95% perfect and even still has the "green tinge" to it. The dial is amazing and really super clean from a time piece of 1933! The 3 Mickey Mouse rotating seconds disk as well is original and spectacular for it's age. The movement I cleaned properly of coarse and changed the mainspring. This is an original Ingersoll USA made timepiece and the band is early 1950's and perfect. As clean as can be all original and keeps time. 1933...incredible indeed.  There are no personal engravings on this snap in back.
