摘要： A super hard wristwatch case where cracks and chips caused by attaching and detaching spring rods for installing a wristwatch band are prevented from being produced in leg portions of a case body. This is achieved by a simple modification to the structure of the case. The super hard wristwatch case has a shock-resistant metallic back cover (2), which has on its face left/right pairs of projection portions (20a, 20b, 21a, 21b) having fixing holes (22a, 22b, 23a, 23b) for spring rods (3), opened near the tips of the projection portions. The projection portions (20a, 20b, 21a, 21b) are on the face opposite a case body (1) so as to correspond to inner wall faces of leg portions (11a, 11b, 12a, 12b) of the case body (1). Each of the projection portions (20a, 20b, 21a, 21b) of the back cover (2) is fitted and fixed in the inner wall face of each of the leg portions (11a, 11b, 12a, 12b). The spring rods (3) are bridged and engaged between the projection portions (20a, 20b, 21a, 21b).

摘要： PROBLEM TO BE SOLVED: To assemble a wristwatch band by securely holding side pieces by means of a connection pin and securely retaining a center piece from both sides by the side pieces without using such a constitution that each shaft end of the connection pin projecting outward from each insertion hole of the center piece is press-fitted in the fixing hole of the side piece. SOLUTION: Connection pins 2a, 2b are insereted in insertion holes 10a, 10b, 11a, 11b of respective center pieces 1a, 1b, etc. Each shaft end of the connection pins 2a, 2b projecting from the adjacent insertion holes 10a, 10b, 11a, 11b of these center pieces 1a, 1b, etc., is inserted in fixing holes 30a, 30b, 31a, 31b of the side pieces 3a, 3b, to hold the center pieces 1a, 1b, etc., from both sides by the side pieces 3a, 3b, etc. Further, stopper pieces 4a, 4b are inlaid into spot facing holes 4a, 4b of the side pieces 3a, 3b, etc., and projections 40a, 40b, 41a, 41b are engaged with respective steps 20a, 20b, 21a, 21b of the connection pins 2a, 2b and further the side pieces 3a, 3b, etc., are held by the connection pins 2a, 2b.

摘要： PROBLEM TO BE SOLVED: To provide a wrist watch case of unique structure with threedimensional effect giving novel design as an accessory while having excellent waterproofness and allowed to be a skeleton type with simple hollow suspension support structure. SOLUTION: A watch movement is enclosed almost at the center part inside a watch case body formed in approximately hollow cylindrical shape or hollow polygonal shape using a transparent hard material with the inner and outer surfaces polished in mirror finished surfaces, and an inner frame body connecting member for enclosing, holding and fixing the watch movement is enclosed at the center of the cylinder. A cover body provided at a connection part to the inner frame body connecting member is arranged on at least one side of both end opening parts of the watch case body. Both end opening parts of the watch case body are covered with the cover bodies, and both cover bodies are integrally connected and fixed to the respective end parts of the inner frame body connecting member.

摘要： PURPOSE:To obtain the band parts for wrist watches easy in machining and excellent in dimensional accuracy by composing a work part by the material to be worked more excellent in machinability than the remaining base member and subjecting the material to be worked to joining with diffusion to the base member. CONSTITUTION:The material 3 to be worked is buried in the inner hole formed on the base 2 consisting of a sintered hard alloy on the work material 1 for wrist watch band. This work material 1 for wrist watch band buries a sintered material 3 to be worked into the hole of the base member 2 which is prior to sintering and after sintering the base member 2 it is obtd. by not isostatic pressing press forming. The material to be worked having excellent machinability is joined with diffusion joining and the material 3 to be worked is more excellent than the base member 2 in machinability, hence the band parts for wrist watch eacy in machining and excellent in dimensional accuracy are obtd.

摘要： PURPOSE:To achieve a highly accurate working with easier machining, by arranging a working part made up of a working material superior in the machinability to a base member while the working material is joined on the base member by diffusing joint. CONSTITUTION:A working material 2 already sintered is buried into a hole 1a of a base member 1 yet to be sintered, and after the sintering of the base member 1, it is subjected to a HIP molding to make a raw working material for a timepiece frame. Then, a working material with excellent machining property is joined on a working part of the raw working material for a timepiece frame by diffusion joint. In this manner, being superior in the machinability to the base material, the working material is easy to machine allowing machining at a high accuracy, which eliminates the need for electric discharge machining to ensure machining in a short time. In addition, as the working material is joined by diffusion joint, it can be joined on the base member in the sintering or HIP molding, thereby highly simplifying the production process dispensing with a soldering process.

摘要： PROBLEM TO BE SOLVED: To prevent the leg sections of a case body from cracking or chipping off owing to attachment or detachment of spring rods for fitting a pair of watch bands, by a simple change in its constitution.
SOLUTION: This cover is provided with a rear cover 2 which is made of metal, is shock-resistive, and has right-and-left pairs of projecting pieces 20a, 20b, 21a, 21b having fixing holes 22a, 22b, 23a, 23b for fixing spring rods 3 near their projection ends, and formed on the surface facing the case body 1 of the rear case corresponding to the internal surfaces of the leg sections 11a, 11b, 12a, 12b. Along with fitting and fixing each projecting piece 20a, 20b, 21a, 21b of the rear cover 2 to the internal surface of each leg section 11a, 11b, 12a, 12b, the spring rods 3 are crossed over and fixed between the projecting pieces 20a, 20b, 21a, 21b.
