Abstract

1374708 Watches LA NATIONALE SA 12 May 1972 [24 May 1971] 22527/72 Heading G3T A waterproof pusher for use e.g. in a chronograph comprises a tube 1 for securement to a watch case 2, a pusher head 3 which slides over one end of the tube and is tapped to receive a screw 12, and a spring 15 which normally holds the head 14 of the screw against an end flange 10 of the tube, the screw head 14 being of a non- circular cross-section. The screw 12 may thus be unscrewed by a tool engaging the periphery of the head 14 and engagement is unaffected if the length of the head is reduced to suit the chronograph movement. As shown the head 14 is hexagonal but it may be square, oval, or splined. A waterproofing gasket 6 is retained by a ring 8.
