Abstract

Abstract 1,099,996. Clocks and watches. H. U. KLINGENBERG. April 28, 1965 [April 28, 1964], No. 17792/65. Heading G3T. The glass 13 of a watch fits in a recess 14 of a caseband and is held to a sealing gasket in known manner by partially evacuating the case. The glass is also secured by claw member 19 fixed to the caseband. These members may be of triangular shape, Fig. 1 (not shown). There may be six, of which one is notched to mark the twelve o'clock position. As shown, the members are retained by stems 20 which pass through into recesses 18 and are locked by U-clips 24 engaging recesses 21. The claws can alternatively form part of a unitary member, and some of them may form part of a means for attaching the strap in place of lugs (2). The glass can be of sapphire and faceted to give a decorative effect in conjunction with the claws. Some of the claws may be integral with the case.
