Problems solved by technology

[0004] However, the exterior parts of Patent Document 1 are for improving the decorativeness, not for protecting the main body of the timepiece.
For example, in the case of using a ceramic bezel, the bezel may be damaged if the watch is dropped
In particular, in the case of a diving watch with a rotating bezel that displays diving time, etc., if an impact is applied, the rotating bezel may be damaged and cannot move, and cannot function
In addition, many users usually wear watches on the left wrist, and the outer casing around the crown is mostly exposed to the outside of the clothes, so it is easy to be damaged in daily use.

no. 1 Embodiment approach

[0024] Such as Figure 1 to Figure 7 As shown, watch 1 is a deep diving watch worn on the user's wrist. A diving watch is a type of diving watch. The wristwatch 1 has an exterior case 2 , a windshield glass 3 and a back cover 4 . A dial 5 , a movement, an hour hand 6 , a minute hand 7 and a second hand 8 are provided in the exterior case 2 . Hour hand 6, minute hand 7 and second hand 8 are driven by the movement.

[0025] The exterior case 2 has an opening 2 a and a second opening different from the opening 2 a. The windshield 3 is arranged in the opening 2a, and the rear cover 4 is arranged in the second opening. Hour hand 6, minute hand 7 and second hand 8 indicate the time. The dial 5 has an indication 9 . The mark 9 is the scale of the hour hand 6 , the minute hand 7 and the second hand 8 .

[0026] The direction toward the mark 9 c at 3 o'clock with respect to the axis 6 a of the hour hand 6 is referred to as a 3 o'clock direction 11 . The direction toward the mar...

no. 2 Embodiment approach

[0044] This embodiment differs from the first embodiment in that the shape of the protective member 19 is different.

[0045] In addition, the same code|symbol is attached|subjected to the same structure as 1st Embodiment, and overlapping description is abbreviate|omitted.

[0046] Such as Figure 8 to Figure 14 As shown, the watch 26 has an exterior case 2 . The protective member 27 is fixed to the side surface 2 c of the exterior case 2 in the 3 o'clock direction 11 . The protective member 27 is fixed on the exterior case 2 by two bolts 20 . The protective member 27 covers a part of the side surface 2 c of the exterior case 2 and a part of the side surface 17 b of the bezel 17 . According to this structure, since the watch 26 has the protection member 27 covering a part of the side surface 2c of the exterior case 2 and a part of the side surface 17b of the bezel 17, the exterior can be protected by the protection member 27 even when an impact is applied. Case 2 and bezel...

no. 3 Embodiment approach

[0048] This embodiment differs from the first embodiment in that the shape of the protective member 19 is different.

[0049] In addition, the same code|symbol is attached|subjected to the same structure as 1st Embodiment, and overlapping description is abbreviate|omitted.

[0050] Such as Figure 15 As shown, the watch 30 has an exterior case 2 . The protective member 31 is fixed to the side surface 2 c of the exterior case 2 in the 3 o'clock direction 11 . The protective member 31 is fixed to the exterior case 2 by bolts 20 and the like. The protective member 31 covers a part of the side surface 2 c of the exterior case 2 and a part of the side surface 17 b of the bezel 17 . According to this structure, since the watch 30 has the protection member 31 covering a part of the side surface 2c of the exterior case 2 and a part of the side surface 17b of the bezel 17, the exterior can be protected by the protection member 31 even when an impact is applied. Case 2 and bezel 17....

Abstract

The present invention provides a watch capable of protecting an exterior case and a bezel around a crown without impairing operability. The watch (1) is provided with: an outer case (2) having an opening (2a); a windproof glass (3) disposed in the opening (2a); a crown (18) disposed on a side surface (2c) of the exterior case (2); a bezel (17) disposed around the windshield (3); and a protective member (19) fixed to the side surface of the outer case (2) on which the crown (18) is disposed, the protective member (19) covering at least a part of the side surface (2c) of the outer case (2) and at least a part of the side surface (17b) of the bezel (17), and having a cutout (19a) exposing the crown (18).

Description

technical field [0001] The present invention relates to watches. Background technique [0002] Patent Document 1 discloses a watch in which a ceramic exterior member is attached to a side surface of a metal exterior case. According to Patent Document 1, since the exterior member is formed of ceramics, impact resistance is weak. Therefore, it is characterized in that the screws, the crown, and the lugs protrude outward more than the exterior parts. Thus, for example, when the wristwatch is dropped, damage to the exterior parts is suppressed. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2016-176725 [0004] However, the exterior member of Patent Document 1 is a member for improving the decorativeness, and is not a member for protecting the main body of the timepiece. For example, in the case of using a ceramic bezel, the bezel may be damaged when the watch is dropped. In particular, in the case of a diving watch having a rotating bezel for displaying diving t...
