A beautiful example of this rare Patent centre-seconds watch, of which very few are recorded.
Gold double back 'crystal' case hallmarked London 1862, casemaker HW (Henry Webb, Clerkenwell). Keywound half plate fusee movement jewelled to the centre of unusual calliper, with the 4th wheel, at the centre, driving a large intermediate pinion/wheel which drives what in effect is a duplicate 4th wheel, which in turn drives the escape. Single-roller detached lever escapement. Compensation balance, spiral balance-spring. Perfect enamel dial signed UNIVERSAL SECONDS, with original matching blued-steel hands. 49.5 mm diameter.
Edward Daniel Johnson (1816-1889), 9 Wilmington Square, Clerkenwell, famous London watch and chronometer maker, holder of numerous Patents and a founder member and for many years Vice-President of the British Horological Institute. Patent No 1941, August 1862, a continuation of/improvement on Patent No 2701, November 1855 - see pic showing the Patent Abridgement. The centre seconds hand can be stopped and started, at will, by depressing and releasing the button in the pendant. NB: In this watch the button can be turned to lock it in the down position, for constant running - there is no provision for setting the hand to zero.
Bright & Sons, at this time with shops both in Sheffield and Scarborough, energetic retailers of often very interesting watches, including the work of good London makers as well as the German firm of Lange & Sohne.
In very good and original condition, the best of the few watches of this type known to me. Cleaned, guaranteed and a most wearable size. Supplied with a proper fitting key, if required.
