This watch is the last tourbillon that the firm Dent, or rather North & Son, submitted to the Kew-Teddington observatory. We estimate that the watch was probably built as early as 1924, because it had already been tested at Kew once before: on page 859 of the supplement to Vaudry Mercer‘s "Edward John Dent", the Dent no. 61434 is listed in June 1925 - before the 1927 entry; it is described as "gold, keyless" and the case is apparently the same as now. As Kew no. 18900 it achieved 82,8 marks and the designation "especially good"; however, the company must have expected a better result because they submitted the watch again two years later as Kew no. 19413 - this time it was awarded 86,7 marks.
The movement is clearly a creation of the Nicole Nielsen company; the tourbillon is very typical of their work. It is described in detail as "Nielsen 1" on page 47 of Reinhard Meis‘ "Das Tourbillon", 1986: "In particular it was the company "Nicole, Nielsen & Co.", who mass-produced this type of watch... almost all of these – ébauches – were sold to well-known companies..... who signed them with their own name"; a footnote states: "Information about the company Nicole, Nielsen & Co. is scarce, but the watches indicate that as early as at the turn of the century many of the special parts were purchased in Switzerland".
