Embodiment

The utility model is specifically related to a kind of wrist-watch that can realize opening greatly face, the wrist-watch that just figure case can be done relatively largely, the form scope is big, and its preferred embodiment such as Fig. 2 are to shown in Figure 4.

As shown in Figure 2, wrist-watch comprises watchcase 3, top cover 1, bottom 6, inner cover 5, letter disk 2, cartridge assemblies 8, elastic spacing one 4, arbor 7 compositions.Wherein, watchcase 3 is the annular tubular structure of hollow, and top cover 1 is generally clear glass spare, and it covers and play effect attractive in appearance, that can watch pointer and letter disk 2 on watchcase 3 upper surfaces.6 of bottoms are generally nontransparent material and make, so that 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 are sealed watchcase 3 and are surrounded an enclosure space, and inner inner cover 5 and the cartridge assemblies 8 of protection is not damaged.Arbor 7 is used to adjust 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.Then 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 a fitting surface, and it contacts assembling with elastic spacing one 4.
