Abstract

916,248. Watches. JUNGHANS A.G. GEB. Aug. 4, 1959 [Aug. 6, 1958], No. 26518/59. Class 139. A stop watch has a minute scale 18, a hundredths of a minute scale 15 and a thousandths of a minute scale 19. The scale 15 is marked on a dial 14 and has a diameter greater than the dial radius, the dial being cut away to reveal the scales 18 and 19 the pointers of which have three arms which move successively over the scales. The minute graduations on scale 18 are arranged in differently coloured series and the corresponding pointer arms are similarly coloured. In a modification the minute scale is marked on a a disc which rotates behind a circular opening. In another modification the minute pointer has two arms.
