The images of the lot also form part of the online condition report for the lot provided by Sotheby's. Any reference to condition in the online condition report does not amount to a full description of condition. The online condition report may make reference to particular imperfections of the lot but you should note that the lot may have other faults not expressly referred to in the online condition report of the lot or shown in the online images of the lot (for example, the online condition report may not specify mechanical replacements or imperfections to the movement, case, dial, pendulum, separate base(s) or dome). Watches in water-resistant cases have been opened to examine movements but no warranties are made that the watches are currently water-resistant. The online condition report may not refer to all faults, restoration, alteration or adaptation but rather the online condition report is a statement of subjective, qualified opinion (for example, information regarding colour, clarity and weight of gemstones are statements of opinion only and not statements of fact). Please also note that we do not guarantee the authenticity of any individual component parts, such as wheels, hands, crowns, crystals, screws, bracelets and wrist bands, since subsequent repairs and restoration work may have resulted in the replacement of original parts.

Galerie Koller Zürich, November 1985
Reinhard Meis, Das Tourbillon, 1986, p.259 & figs.346-346a

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.
