C.1875, English, Wassell & Halford, 43 Fenchurch, London, miniature wall hanging astronomical regulator in excellent original condition.
Although such small clocks turn up occasionally in the UK, this is the first time we have ever examined a clock of this size and quality. The 8-day movement is made to a very high standard with a 60 tooth escape wheel and Graham's dead beat escapement to show half seconds on the seconds dial and rotate once per minute. The silvered brass dial is engraved by the makers as shown in the headline of this description, and with typical precision dial layout with center minutes, hours at 6 and seconds at 12. The pendulum appears to be a round invar rod and lead filled silvered brass cylinder, and compensates reasonably for changes in temperature. John Halford was working in Oxford St in London in 1845, and in 1870 started the partnership with Charles Wassell who was working at his Fenchurch shop. Depth = 5.6", width = 11.25", height 31 inches
