Chronograph with unusual 'Registered' tachymeter scale marked in black and red, circa 1910.
Swiss 0.935 silver openface case, casemaker JP (cameo) and numbered 112104. Three-quarter plate keyless going-barrel movement with all the chronograph work mounted on the top plate, and with Smiths 'time ball' trademark. Straight line detached lever escapement with club-tooth escape. Compensation balance, balance-spring with overcoil. Signed enamel dial in perfect condition with 30-minute counter at 12, blued-steel hands. 51 mm diameter.
Samuel Smith & Sons 'Makers to the Admiralty' 9 Strand, London, one of the largest retailers of Swiss and English made precision and technical pocket watches of the period. See the reprint of Smiths Guide to the Purchase of a Watch, for further information about Smiths, copies of which are generally available on my website. This exact design of tachymeter dial is not shown and is presumably later than the circa 1900 date of the catalogue. NB: Many of Smiths Swiss watches had their name added to the enamel dial in paint that will wash off if cleaned - the Smiths name and address on this watch is fired into the enamel.
Case and movement showing just a few signs of use, otherwise in good original conditional. Serviced and guaranteed.
