Embodiment

The present invention is specifically related to a kind of wrist-watch that can realize wide open face, the wrist-watch that namely figure case can be done relatively largely, the form scope is large, and its preferred embodiment such as Fig. 2 are to shown in Figure 4.

As shown in Figure 2, wrist-watch comprises that watchcase 3, top cover 1, bottom 6, inner cover 5, letter disk 2, cartridge assemblies 8, elastic spacing one 4, arbor 7 form.Wherein, watchcase 3 is the annular tubular structure of hollow, and top cover 1 is generally clear glass spare, and it covers on watchcase 3 upper surfaces and plays effect attractive in appearance, as can to watch pointer and letter disk 2.6 of bottoms are generally nontransparent material and make, in order to cover in the cartridge assemblies 8 of wrist-watch back side complexity, can also protect internal machine core assembly 8 to avoid direct infringement simultaneously.Top cover 1 and bottom 6 seal watchcase 3 and surround an enclosure space, and inner inner cover 5 and the cartridge assemblies 8 of protection is not damaged.Arbor 7 is used for adjusting the initial time of wrist-watch, and it passes watchcase 3 and is connected with cartridge assemblies 8.

As shown in Figure 3, inner cover 5 has the cavity that holds cartridge assemblies 8, and cartridge assemblies 8 is packed into wherein, can realize firm installation by certain assembly relation.Realize by elastic spacing one 4 and bottom 6 location of inner cover 5 relative watchcases 3.The upper surface of inner cover 5 is fitting surface, and it contacts assembling with elastic spacing one 4.
