Embodiment Construction

[0023] reference Figure 1-6 , Describe an embodiment of the present invention.

[0024] in figure 1 Here, reference numeral 11 denotes a timepiece, such as a portable timepiece having a function of screwing and locking the crown 12, and specifically a wristwatch. Such as figure 2 As shown, the watch 11 accommodates a dial 14, a timepiece movement not shown in the drawings, and the like in its timepiece protection assembly 13. The timepiece movement can be any movement whose power is a small battery or a large spring, or a movement that is automatically wound, or a number that displays time and similar information on the dial 14 through a quartz oscillation module. The movement corresponding to the timepiece, or a movement in which the movement corresponding to the digital timepiece is used in combination with other movements, or a similar movement.

Abstract

Providing a timepiece in which it has been made possible to exchange an edge member to which a glass has been fixed, without accompanying a case band. A wristwatch comprises an annular case band, provided with a front side end part of the case band forming a fitting hole has an edge receiving face around the fitting hole and an engaging groove; a case back detachably attached to a back side end part of the case band; an annular edge member provided with a tubular part fitted to the fitting hole so as to be capable of being inserted and disengaged, and a cover part overlapping with the edge receiving face; an annular attaching groove opening to an inner periphery of the tubular part, and plural through-holes communicating with the annular attaching groove and opening to an outer periphery of the tubular part; a glass fitted and fixed to an annular step part having been formed in the edge member; and a C-shaped spring member having plural catching convex parts catching to the engaging groove through the through-hole.

Description

Technical field [0001] The present invention relates to a timepiece such as a portable watch such as a wrist watch, a pocket watch, a table clock, and a wall clock. Background technique [0002] Heretofore, among watches with a case back cover, there are known watches in which a ring-shaped protruding portion is formed in the inner periphery of the front side end of the case band accommodating the dial, and the glass case covering the dial is installed and fixed here On the inner periphery of the annular projection, and a tubular part serving as a rim member of the bezel is installed on the inner periphery of this annular projection, and the blocking part integral with this tubular part is blocked on the rear surface of the annular projection ( For example, refer to JP-UM-B-5-37273 Bulletin). [0003] In a watch in which the edge member is jammed into the case band as described above, since the deformed jam part is blocked again after returning to the state before the jam, the mec...
