Catalogue Note

The Longines archives note that this watch was delivered to Herpy Arnold in Budapest and invoiced on 22 June 1925. Manufactured by Longines with a lever escapement, the calibre 24.99 movement was later expertly modified by an unknown but highly skilled watchmaker to incorporate a flying tourbillon with spring detent escapement. Whilst it is not known who carried out the transformation, as Richard Meis notes in his authoritative book, Das Tourbillon, the tourbillon's style suggests a German origin, Meis writes: "certainly many of the excitements of the German watchmaking school in Glashütte have been realised here, possibly it is the work of a former DUS student or master who made their Tourbillon outside the DUS" [translated from the original German text of R. Meis, Das Tourbillon, 1986, p.259]

Gyula Herpy of Budapest, was a successful retailer who began his business in 1817 by importing and selling predominantly Swiss clocks and watches to Hungarian clients. The business was nationalised after the Second World War.
