Although not signed as such, the watch appeared to be an IWC calibre 72. This calibre is considered a premium packet watch movement that had been prepared for successful tests at Kew observatory or issued as deck watches for the Royal Navy. lt was built In two series of 600 watches, each in 1904 and 1917 respectively. Many watches of both series were exported to the UK.
The current watch dates from the first 1904 series and was bought by IWC wholesaler Stauffer, Son & Co., London on 31 October 1911. Together with five other IWC pocket watches, Stauffer sent this watch to Kew for chronometer testing. lt can be assumed that all were IWC cal. 72 hunters as they had consecutive numbers, 305185-305190. The testing was carried out in November and December 1911. All five of the watches submitted successfully passed the test and were rewarded with Kew 'A' certificates. The present watch obtained a score of 77.7 marks out of 100.
The dedication on the gold dome refers to Thomas Graham Menzies Esq., who had worked for the Royal Naval Cordite Factory, Holton Heath, Dorset. This was an explosives factory that used cordite as a propellant to fire heavy shells over long distances by naval guns. The watch was donated to him by "Nobel's Glasgow", an enterprise founded by Alfred Nobel in 1871. After the First World War he received a Royal Navy medal Commander of the Civil Division Most Excellent Order of the British Empire.
This watch is described and illustrated in detail in "The Horological Journal", Official Journal of the British Horological Institute Ltd, October 2022 edition, p. 110ff.
In the first 50 years of IWC's existence, the company sold many movements to other makers.The thought was to produce inexpensive movements in Switzerland and expot them to the U.S or England. The buyers completed the watches with cases, dials and hands. Later IWC produced movements and on occasion cases for Stauffer, Son & Co. in London. These movements carry the designation "PEERLESS" and a stamp "S & Co." in a crowned oval.
