Viner & Co London, retailers of many interesting and unusual watches in the first half of the 19th century, many of which they claim to have invented or to be the patentees. This appears to be a marketing statement as not a single patent was ever taken out by the firm and, instead, they retailed watches designed and patented by others.
NB: This winding work is a version of that patented by Joseph Anthony Berrollas, Patent No 5586, in December 1827, a similar version of which was later patented by Edward John Massey in 1841, itself a version of his earlier pump-wind patent, No 3854, of 1814. Both Berrollas and Edward Massey are among the most inventive watchmakers of the first half of the 19th century. Similar pump- and pull-wind mechanisms were designed and made in Paris and Geneva at this period, prior to the superior Nicole & Capt patent keyless watches that were introduced in London by 1845.
The light engine-turning on the case showing some wear, as to be expected, otherwise in fine original condition and uncommon being in gold and of a larger size than usual. Serviced and guaranteed
