A heavy burnished brass 8-days Omega keyless Art Deco chronometer window presentation clock “l’Heure Exacte”, ref. 32.590, case no. 8676598, made circa 1930s. Driven by a high grade cal. 59.8-D mechanical 8-days movement, 15 jewels, two-tone silvered dial, Roman numerals, outer railway minute divisions, subsidiary seconds, triangular base and frame, dial and movement signed.
This particular exemplar is very interesting and unusual, because of missing engraving “l’Heure Exacte” on the case below the dial. The dial is signed “Importe de Suisse” under 6h, means it was made for export to France, on all others I’ve seen in Internet and in the AJTT book it’s signed “Fabrique en Suisse” or “Fabrication Suisse”, so I believe it was an export ebauche/unfinished version, where engraving should have added later, but was not added for some reason.
This clock can also be found in the Omega Book “A journey through time” by Marco Richón, page 178, item 2418.
Dimensions : 15 x 16 x 10.5 cm, shipping weight is 5 kg.
