PROBLEM TO BE SOLVED: To provide a wrist watch adapted to facilitate the disassembling of a spherical case so that a treatment of an internal time register can be performed. SOLUTION: The case 22 of the watch comprises an annular hollow housing 36 having a spherical outer wall, a windshield 31 for closing an upper opening of the housing 36, the time register 41 stored in the housing 36, and a lower spherical body 32 for closing a lower opening of the housing 36. The windshield, the housing 36, and the lower spherical body are mutually bonded to constitute the case 11 having a spherical outer surface. The lower spherical body 32 includes a core 37 bonded to an upper part thereof. The core 37 is inserted into the inside of the housing 36, and an engaging projection 38 of the core 37 is engaged with an engagement groove part 43 in the inner wall of the housing 36, whereby the lower spherical body 32 is attached to the lower part of the housing 30.
