Abstract: An electronic watch which is both thin and water resistant. The watch comprises a back, a bezel and an electronically controlled module for digitally displaying a time signal. Its crystal includes an upper member the lower surface of which is adjacent to the upper surface of the module, a first flange extending downwardly from the edge of the upper member adjacent to the side of the module and a second flange which extends laterally outwardly from the bottom of the first flange. Contact means is provided which has a longitudinal portion sealed into the first flange and an inner end which is electrically connected to the module. A plunger is mounted for axial movement in a bore in the bezel and its inner end is engageable with the contact means. A sealing member is positioned between the second flange of the crystal and an upper surface of the back. It also includes means for holding the upper surface of the back against the sealing member.

Abstract: An electric-optic display device having an electrically controllable optical means for selectively indicating one of the seven days of the week by means of a combination of two letters. The device comprises two arrays, a first array composed of a plurality of segments arranged in such a pattern that all of the letters positioned in the first place of the seven combinations expressing the 7 days of the week can be indicated. The second array is composed of a plurality of segments arranged in such a pattern that all of the letters positioned in the second place of the seven combinations can be indicated. The first letters of the days of the week are formed in uppercase letters, the second letters of certain days of some days of the week are formed about one-half as high as the first letters of the days of the week and the second letter of at least one day of the week is formed as a lowercase letter.
