The watch main body 2 and the band 3 are connected at the band mounting portion 30 , and the connecting portion is covered with the decorative member 4 and the tip cover 5 . The band 3 is formed in an elongated shape extending in the YZ plane, and one end of the band 3 is connected to the watch main body 2 . The band 3 is made of soft synthetic resin such as urethane resin and has flexibility.

In the band attachment portion 30, two bearing portions 21a are provided juxtaposed in the X direction on both sides in the Y direction on the outer surface of the main body case 21. As shown in FIG. On the other hand, three bearing portions 31 arranged side by side in the X direction protrude from the base end portion of the band 3 (the end portion on the watch body portion 2 side). The watch body 2 and the band 3 are composed of the two bearings 21a of the body case 21 and the three bearings 31 of the band 3 arranged alternately in the X direction, and both sides in the X direction are covered. 5 are connected (fixed) to each other by two screws 61 passing through them in the X direction. The band 3 is fixed to the watch main body 2 with its longitudinal direction substantially along the Z direction. The two screws 61 are fastened with a sufficiently strong fastening force with respect to the bending rigidity of the band 3 .

A front button 26 is arranged on the band attachment portion 30 on the 6 o'clock side.
The front button 26 is arranged to face obliquely to the front in the 6 o'clock direction, and is supported by the watch main body 2 (main body case 21) so that it can be pressed in this oblique direction. The front button 26 is connected to the timepiece module 25 at the tip of a shaft portion (not shown), and is configured so that the timepiece 100 performs a predetermined operation when pressed.
Further, the periphery of the front button 26 is protected by the decorative member 4 . The decorative member 4 has a hole 41 at a position corresponding to the front button 26 , and covers the front button 26 while exposing the front button 26 to the front side through the hole 41 . Thus, the decorative member 4 protects the front button 26 while guiding the movement of the front button 26 in the pressing direction.

In addition, in the band attachment portion 30, the connecting portion between the watch main body portion 2 and the band 3 is covered with the decorative member 4 and the tip cover 5, as described above.
The tip cover 5 covers the connection between the watch main body 2 and the band 3 from the back side. The tip cover 5 restricts the rotation of the band 3 toward the back side with respect to the watch main body 2 .

The decorative member 4 is a second exterior member according to the present invention, and covers the connecting portion between the watch main body 2 and the band 3 from the front side (viewing side). The decorative member 4 of the present embodiment is made of carbon fiber-containing epoxy resin, and has flexibility and relatively high rigidity. Specifically, the decorative member 4 has a member body 42 and two projecting portions 43 .
The member body 42 is a portion that covers the connecting portion between the watch body 2 and the band 3 . More specifically, the member body 42 covers the connecting portion between the watch body 2 and the band 3 with almost no gap between it and the band 3 when viewed from the outside (viewing side).
The two protrusions 43 are provided on both sides of the member body 42 in the X direction and inside in the Y direction (inside the watch body 2). The two projections 43 each have a through-hole 43a, and the decorative member 4 is fixed to the watch body 2 by fastening the screw 62 inserted through the through-hole 43a to the body case 21. .

FIG. 5 is a perspective view of the decorative member 4 (on the 12 o'clock side) viewed obliquely from below, and FIG. 6 is an enlarged view of the portion B in FIG.
As shown in these figures, each projecting portion 43 has a cover portion 44 arranged on the front side of the bezel 22 and extends in a direction (front direction) substantially perpendicular to the extending direction of the cover portion 44 . It has a fixed portion 47 that supports one side (outer diameter side) of the cover portion 44 . The cover portion 44 is the frontmost (upper) portion of the projecting portion 43, extends along the radial direction, and is arranged so that the tip thereof faces the inner diameter side.
The cover portion 44 has an upper surface 45 having an apex portion 45a located on the frontmost side, and a lower surface 46 having a radially concave bent portion 46a. The upper surface 45 is formed in a shape inclined upward toward the inner diameter side, and has a vertex portion 45a near the innermost portion thereof. The lower surface 46 has an outer diameter side portion that slopes upward toward the inner diameter side and an inner diameter side portion that is inner diameter side than the outer diameter side portion and is substantially flat. is a bent portion 46a.
A vertex portion 45a of the upper surface 45 is arranged on the inner diameter side of the bent portion 46a of the lower surface 46. In this embodiment, the vertex portion 45a and the bent portion 46a are separated by a distance L in the radial direction.

A gap S is interposed between the cover portion 44 and the bezel 22 . The gap S is provided at least below the tip of the cover portion 44 and is formed so as to gradually widen toward the inner diameter side.
Specifically, the upper surface of the bezel 22 facing the lower surface 46 of the cover portion 44 has a tapered surface 22a that slopes downward toward the inner diameter side. The tapered surface 22 a faces the flat inner diameter side portion of the lower surface 46 of the cover portion 44 . Therefore, the gap S between the cover portion 44 and the bezel 22 gradually widens toward the inner diameter side (the tip side of the cover portion 44).
However, it is sufficient that a gap S is interposed between the cover portion 44 and the bezel 22, and the specific shape and the like related to the gap S are not particularly limited. For example, the upper surface of the bezel 22 may be flat, and the lower surface of the cover portion 44 may be inclined upward toward the inner diameter side.
The shape, material, etc. of the cover portion 44 are not particularly limited as long as they are configured to be deformable. For example, the cover portion 44 may be supported (fixed) at a portion other than the outer diameter side (fixed portion 47), may not be made of a flexible material, and may extend in the same direction as the present embodiment. not limited to

When the timepiece 100 configured as described above receives an impact from the front side, for example, by being dropped, the apex 45a of the cover portion 44 of the decorative member 4, which is located closest to the front side, first hits the contact partner. come in contact and receive a shock.
At this time, since a gap S is interposed between the cover portion 44 of the decorative member 4 and the bezel 22, the impact applied to the decorative member 4 is not immediately transmitted to the bezel 22, and the cover portion 44 is positioned downward. contacts the bezel 22 after being deformed into . Therefore, the cover portion 44 can preferably absorb the impact.

Further, at this time, the deformation of the cover portion 44 is such that the distal end side bends downward with the bent portion 46a of the lower surface 46 as a deformation starting point. That is, the radial distance L between the vertex portion 45a of the upper surface 45 and the bent portion 46a of the lower surface 46 is the deformation length. Therefore, by appropriately setting the distance L, a suitable impact absorption amount can be obtained.
However, if the distance L is too short, the amount of impact absorption due to deformation will be reduced, but if the distance L is too long, the amount of deformation will increase and the cover portion 44 may crack. Therefore, it is preferable that the distance L is set to an appropriate length so as to reduce the risk of cracking due to deformation while obtaining a suitable amount of shock absorption.

As described above, according to the present embodiment, the gap S is interposed between the bezel 22 and the cover portion 44 of the decorative member 4 arranged on the front side of the bezel 22, and the cover portion 44 is deformed. configured as possible.
Therefore, when receiving an impact from the front side, the impact applied to the cover portion 44 is not immediately transmitted to the bezel 22, and the cover portion 44 contacts the bezel 22 after being deformed. Therefore, it is possible to suitably absorb the impact.

Further, according to the present embodiment, the cover portion 44 has an upper surface 45 having an apex portion 45a located on the frontmost side, and a lower surface 46 having a bent portion 46a bent in a concave shape in the radial direction, The vertex portion 45a is arranged closer to the distal end side of the cover portion 44 than the bent portion 46a.
Therefore, the impact from the front side first acts on the vertex portion 45a, and the impact causes the cover portion 44 to deform with the bending portion 46a as the starting point of deformation. Therefore, it is possible to control the deformation mode of the cover portion 44 and, in turn, control the amount of impact absorption.

Further, according to this embodiment, the gap S between the cover portion 44 of the decorative member 4 and the bezel 22 is formed so as to gradually widen toward the distal end side of the cover portion 44 in the radial direction.
As a result, the cover portion 44 can be suitably deformed when receiving an impact from the front side, and thus the impact can be suitably absorbed.

It goes without saying that the embodiments to which the present invention can be applied are not limited to the above-described embodiments, and that various modifications are possible without departing from the gist of the present invention.

For example, in the above embodiment, the decorative member 4 is made of epoxy resin containing carbon fiber, but the material of the decorative member 4 is not particularly limited. However, it preferably has flexibility and relatively high rigidity.

Further, in the above-described embodiment, the time display section is of an analog type, but it may be of a digital type, or two time display sections, one of an analog type and the other of a digital type, may be provided.

Further, in the above embodiments, the case where the electronic device according to the present invention is applied to a timepiece (wristwatch) has been described as an example.
