La montre-bracelet ultra-mince comporte un fond-carrure (7) et une glace (8) en matière plastique. La boîte est renforcée par une armature métallique (13). Cette armature, en plus qu'elle sert de point d'amarrage à un bracelet, est utilisée comme platine sur laquelle au moins un tenon central (16) est fixé, tenon autour duquel pivotent les aiguilles d'heure (11) et de minute (10)
摘要:
A plastic top shell is disclosed for use on a metallic top link of an expansible watch band, the top link having a hollow box-like configuration with open ends and with top and bottom walls joined by side walls. The plastic top shell comprises a molded body having a top surface and a bottom surface with end tabs protruding downwardly therefrom. The bottom surface has coplanar end portions adjacent to the ends tabs, with the top and bottom surfaces defining a thickness therebetween which is greater than the thickness of the end tabs. The body is configured and dimensioned to overlie the top wall of the top link, with the end tabs being bendable around the open ends of the top link to thereby firmly seat the coplanar end portions of the molded body's surface against the top link wall.

A paste consisting of pasty or granular material coated with additional pigment and then re-pressed is applied to a support (13) in the form of a pressed strip or covering (17). The strip or covering is subjected to a first, incomplete hardening (20), after which it can no longer flow easily under its own weight. After this, the surface coat containing the additional pigment is removed from a surface (24) which is to be used, and then this surface is smoothed (29, 32) and the hardening of the coating is terminated to produce a hard material (29). The smoothing and completion of the hardening process can be effected in the same processing stage as shaping (29) to produce separable shaped parts (34). The support (13) can be inseparable from the hardened coating (19). The surface layer containing the additional pigment can be removed by mechanical means, solution means or by abrasion by a suspension in liquid or air, if necessary in the presence of ultrasound (40, 41). The strip can also be cut in order to form a surface layer free of additional pigment. The process is applicable for the production of moldings resembling gem-stones.

1. Watch case (1) comprising a caseband (3, 40), a bezel (7, 41, 51), a glass (32) and a back cover (31) with the purpose to receive a movement (33) onto which a dial (14, 34, 42) is superposed, characterized by the fact that at least one element of the group of elements comprising the caseband, the bezel and the dial is formed of leather.
摘要:
The bracelet comprises a first strap (4), a second strap (5), one end of each strap being integral with a watch case (1), and a band (7) adjoined to the other end of the second strap. The first strap (4) comprises opening (6) wherein the band (7) may be introduced in order to form together with both straps and the watch case a closed loop intended to surround the wrist of the watch wearer. A press button (9, 11) enables the user to fix the free end of the band (7) in a position where the band is turned in so as to close the bracelet. The bracelet and the case are conveniently made in a single piece of injected synthetic material.
