Rare Patent HERMETIC watch.
Silver two-piece crystal case with snap on bezel (the back does not open) hallmarked London 1886, casemaker GJT (George John Thickbroom), and also stamped R.S (incuse) and PATENT R.S. Fullplate keyless going-barrel movement. Single-roller detached lever escapement. Gold balance, spiral balance-spring. Perfect condition enamel dial signed PATENT HERMETIC within a triangle, and PRIZE MEDAL 1885 underneath. 50.5 mm diameter.
Reuben Squire, 35 Myddelton Sq, London, a most interesting but little known watchmaker working at the heart of one of the most vibrant centres of watchmaking at this period. It included Charles Hector Golay, Victor Kullberg and many others.
Patents Nos 11,852 and 12,199, September 1884. The Prize Medal alluded to on the dial was awarded at the International Inventions Exhibition held in South Kensington in 1885. I have seen only one other example of this unusual watch, as shown in the book Pocket Watches 19th & 20th Century by Alan Shenton, colour plate 8, who also shows an advertisement by Squire for these "New Dust-Proof, Keyless and Key Watches" in the Watchmaker, Jeweller & Silversmith, July 1886, page 10.

In good original condition, but with a few marks (not bad) on the case. Although not cleaned by me it winds and ticks happily but can be freshly serviced if required.
