The movement of the present watch was supplied by Nicole Nielsen, who, towards the end of the Victorian era and for the first 30 years of the 20th century, crafted some of the finest and most complicated English watches ever made. A similar movement is illustrated in The Frodshams by Vaudrey Mercer, p. 418, pl. 89.
In 1839 Adolphe Nicole and Jules Capt, both talented Swiss watchmakers, set up business in London at 80B Dean Street. The firm later moved to 14 Soho Square where it remained until the company finally closed in 1934. Nicole & Capt were highly successful and won medals in many international exhibitions such as Paris in 1855 and 1867, Philadelphia in 1878 and Sydney in 1879. In 1876 Jules Capt died and in the same year his place as partner was filled by the Danish-born watchmaker Sophus Emil Nielsen and the company became Nicole, Nielsen & Co. By 1880 the company was being run by Nielsen. They specialised in making super-complicated keyless watches often incorporating specifications such as perpetual calendar, chronograph, split seconds chronograph, repetition, temperature, equation of time and their most famous escapement; the Nicole Nielsen tourbillon. Invented by Breguet (1747-1823), the tourbillon is an escapement that revolves so that the balance pallets and escape wheel move through all the vertical positions in a given time period, usually once every minute. Delicate, expensive and fascinating to observe the tourbillon was Nicole, Nielsen's specialty. The Company designed their own tourbillon carriage, instantly recognisable and revered by collectors.
