Embodiment

The present invention 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 on watchcase 3 upper surfaces, plays effect attractive in appearance, that can watch pointer and letter disk 2.6 of bottoms are generally nontransparent material and process, so that cover in the complicated cartridge assemblies 8 in the wrist-watch back side, can also protect internal machine core assembly 8 to avoid direct infringement simultaneously.Top cover 1 is sealed watchcase 3 with bottom 6 and is surrounded an enclosure space, and the inner inner cover 5 of protection is not damaged with cartridge assemblies 8.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 through certain assembly relation.Then realize through 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.

As shown in Figure 4, elastic spacing one 4 is for having the ring segment of breach on the circumference, and the width of breach is greater than arbor 7 diameters, and when mounted, indentation, there faces arbor 7, thereby makes whole elastic spacing one 4 avoid arbor 7.The ring segment both ends of breach both sides are provided with colludes position 400, colludes position 400 indents, colludes in the position 400 so that the bipod of instruments such as pliers, tweezers can block two respectively, compress make two collude position 400 near, then the radial elastics distortion takes place and dwindles in elastic spacing one 4.
