“Seconds Striking Chronograph” Swiss, No. 6929. Made circa 1900. Fine, interesting and possibly unique, silver keyless pocket watch with dead-seconds chronograph with one second continuous striking. Four-body, “bassine”, polished, hand setting button with gold lip. Hinged silver cuvette. White enamel with radial Roman numerals, outer minute track and Arabic five minute numerals. Blued steel “spade” hands. Notes This remarkable watch, the specific use of which is unknown, has an ingenious mechanism to both drive the seconds hand and incorporate a strike for each elapsed second. It is in effect a chronograph without a chronograph mechanism. The whole system is simply driven by the beating of the escapement and takes its power via a star-wheel mounted on the escape-wheel pivot, the star-wheel pushes a jewelled pallet at one end of a “V” shaped steel lever which is sprung at its fulcrum to provide recoil, the hammer is also attached at this point and at the other end two posts drive the seconds wheel. The seconds can run without striking or with striking at will.
