The firm of E J Dent ‘Watchmaker to the Queen,’ then at 61 Strand & 4 Royal Exchange, London, one of the most important English watch, clock and chronometer makers/retailers of the second half of the 19th and the early 20th centuries – see the book on Edward John Dent and the various Dent firms by Vaudrey Mercer.
Nicole Nielsen, formerly Nicole & Capt, were the foremost London watchmakers of the second half of the 19th century, supplying many of the finest watches to retailers such as Frodsham, Dent, Smith & Son, and Roskell. See my reprint of Nicole Nielsen’s High Class English Watches trade catalogue and my site Glossary for more information about this most important and still vastly underrated London firm. NB: The firm fitted a great deal of different lever escapements over the years, this movement having their unique banking of the period. This movement also features their snap-on dial which, at this period, have no locating pin, so care must be taken to line up the extended seconds arbor and the hole in the dial!
Lacking hour and minute hands and both balance and escape arbor top pivots broken. Somewhat dirty and not working.
