ABSTRACT:
A digital watch case which includes a cylindrical watch barrel, glass cover, glass sealing means and parting plate mounted from the upper end of the barrel, and a back cover mounted from the opposite end. The watch case is characterized in that the thickness of the watch shell is reduced by providing a receiving surface on a flange of the barrel which extends inside the outer surface of the glass cover. The parting plate supports the glass cover and covers the watch body except for the display area. The back cover is secured to the watch shell by a radial spring means attached to the watch back. Packing means are supported on the back cover to engage compressively with the under horizontal surface of the flange and the back cover.
