Embodiment 1
[0030] Referring to Figures 1-8, a first embodiment of a timekeeping device according to the invention, in particular a digital electronic wristwatch, will be described.
[0031] As shown in Fig. 1, the watch of the present invention has an annular metal case 1, a bezel 2 is connected to the upper end of the case, a crystal 3 covers the upper end of the case, and a gasket 3a is arranged around the crystal. As shown in Figures 1, 2, and 3, the housing 1 accommodates a disc-shaped meter module 4, which is supported by a disc-shaped insulating plastic support 5 (see Figure 5 -7) Positioning, the disc-shaped insulating plastic support 5 basically has the same shape as the meter module. The metal bottom cover 6 is connected to the bottom end of the casing 1 through a waterproof ring 6a.
[0032] Such as Figure 4 As shown, the watch module 4 has an insulating annular plastic bracket 7 in which various components for performing the timing function are housed, such as an analog mo...
Embodiment 2
[0065] refer to Figure 16-21 , an analog wristwatch according to a second embodiment of the present invention will be described.
[0066] Such as Figure 16 and 17 As shown, the watch according to the second embodiment has an annular metal case 1 to which a crystal 3 is attached. The disc-shaped meter module 4 is supported or accommodated inside the housing 1 by a disc-shaped or annular insulating support 5 . Such as Figure 16 and 18 As shown, the metal bottom cover 6 covers the bottom end of the housing 1 .
[0067] Module 4 has an annular plastic bracket 7, which includes the necessary parts to complete the timing function, such as an analog movement 24 (see Figure 16 ), antenna 8, battery 20 and circuit board 10 (see Figure 17 ).
[0068] In analog movement 24 (see Figure 16 ), a stepper motor (not shown) rotates to drive a gear train (not shown), which rotates the hour, minute and second hand shaft 32, thereby making the hours, minutes and seconds connected t...

Abstract
A timepiece apparatus is provided in which a bottom cover (6) is attached to a lower end of a case (1). The bottom cover supports and positions a timepiece module (4) within the case (1) via a support (5). A thin magnetic member (12) of a proper size is positioned at the support (5) so as to face toward an antenna (8) built in the timepiece module (4).
Description
technical field [0001] The present invention relates to timekeeping devices and, more particularly, to electronic wristwatches having radio receiving antennas. Background technique [0002] Electronic watches can be radio controlled using an antenna. As disclosed in published but unexamined Japanese patent application JP2002-98780 (USP6,657,922), such an electronic watch comprises a plastic case with a pair of straps arranged at opposite positions on the periphery of the case, while the antenna is located One of the straps in the inner space, so as not to receive electromagnetic interference from the bottom metal cover of the electronic watch. [0003] The placement of the antenna outside the housing constrains the housing in many ways. For example, the appearance and design of electronic watches are compromised. In addition, the antenna and watch module must be assembled separately and electrically connected. Therefore, the assembly operation is complicated and difficul...
