A watch case (2) for wristwatches including: a middle part (4) including a side wall (10) having two sides (12A, 12B); two separate side members (6A, 6B) arranged on either side of the middle part (4), each side member (6A, 6B) extending beyond the space occupied by the middle part (4) in the longitudinal direction of the watch band and having a median portion of complementary shape to the corresponding side (12A, 12B) of the middle part (4), each side member (6A, 6B) being slidably and removably attached to the middle part (4); a bezel (8) secured to the middle part (4) on an upper face of the middle part (4); a back cover (20) fixed on a lower face of the middle part (4); characterized in that each side member (6A, 6B) is blocked in translation in the direction of sliding on the middle part (4) by the bezel (8).

A watch case includes a middle having a first opening receiving a crystal, opposite a second opening receiving a back. The back is held such that it bears against an annular bearing surface of the middle by a threaded ring cooperating, by screwing, with the middle. The back includes a first indexing element to cooperate with a second indexing element with which the middle is provided so as to immobilise the back in a single angular position such that it cannot rotate relative to the middle.

A watch body and a strap are included. The watch body includes a case body having a cylindrical shape, a movement disposed inside the case body, a cover member covering one opening of the case body, and a case back covering the other opening of the case body and including a transmissive region through which the movement can be visually recognized from the outside and the movement can be visually recognized through the cover member. The strap is attached to the watch body and includes a base facing the case back of the watch body and a strap body coupled to the base. The base includes a decoration at a position overlapping at least a part of the transmissive region, and the decoration can be visually recognized through the cover member.

An exterior member that is favorably manufactured, a case having the exterior member and a timepiece having the case are provided. The exterior member includes an exterior main body section in which a first resin layer is provided on one side of a sheet member formed of carbon fiber and a cutout recess section from which a portion of the sheet member is exposed is provided in the first resin layer on the one side of the sheet member, and a protection member which covers the cutout recess section of the first resin layer. Accordingly, the exterior member is favorably manufactured with its strength being increased.

A bracelet or flexible band comprised of a flexible member that on one end is interconnected to a knife and on another end, is connected to a sheath that selectively receives the knife in the locking fashion. When needed, the knife is rotated within the sheath to facilitate release thereof from a lock that is integral with the sheath. Once removed from the sheath, the knife can be used for self-defense, cutting rope or cord in an emergency situation, or for general utility cutting tasks.

Provided is a device for fastening a back on a middle portion of a watch. The back includes a cover arranged to form a bearing surface with the middle portion and a body arranged to rest in the middle portion. The device includes an indexing ring disposed between the back and the middle portion, and the ring includes at least one lower catch arranged to cooperate with the back and ensure the indexing with the back and an upper catch are arranged to cooperate with the middle portion and ensure the indexing of the back and ring assembly in relation to the middle portion, and the upper catch has a height greater than that of the lower catch, or vice versa.

A device for fastening a back on a middle of a watch, the back having a shoulder forming a cover arranged to cover totally or partially with the middle and a body arranged to rest in the middle, the device including at least one pin integral with the middle and a gasket mounted between the back and the middle. The back includes, close to its periphery, at least one recess, the pin being arranged to slide in the recess between a first position, referred to as insertion position wherein the back is free, and a second position referred to as locking position wherein the back is locked and angularly positioned in relation to the middle. The recess includes at least one bump to form a hard spot and increase the torque during the passage of the pin at the bump.
