For sale we have a beautiful example of Art Deco design from Omega. This is a mid 1930s Omega tank watch with a full stainless steel case measuring 15mm x 24mm without looped lugs. It has rare black dial with gold signing which adds an extra touch of class to this neat watch. The lugs are central and looped, in cocktail watch style. To the right is the original dimpled crown which adds to the elegance of the piece. Inside, the movement is protected by the original movement cover to add dust proofing. The manual wind calibre T12.6 movement has been serviced and is functioning exceptionally well for such a small calibre. This is a very rarely seen style of Art Deco omega, with unusual dial tone and a rare movement calibre, all packaged into the high quality full Stainless-Steel case. It comes with a rare, period omega box


The dial is well executed, with a black base tone and gold railroad track, omega signing and Arabic numerals. This is protected by the stylish, thick cut crystal which adds depth to the watches design.


The Stainless tank case is beautifully designed with a brushed straight section either side of the raised loop lugs. The sides of the case are polished and facetted, falling away from the dial. The sides are flat and lightly brushed which adds a sharpness to the case, balancing well with the curvature to either end of the top of the case. The mix of brushed and polished finishes catches the eye and is important in enhancing the texture of the watch. The dimpled crown is incredibly neat and elegant. These rarely remain of watches of this age in such good condition.


The case back is flat and tightly sealed and has a brushed finish. Inside it is signed Omega, with the serial number clear. The movement is protected by the original movement cover to aid dust proofing. The calibre T12.6 movement is in excellent original condition thanks to this. It has siging for Omega, with a jewel count of 15 and a serial number which dates it to 1935. The balance is cut compensated with Breguet hairspring. It has been serviced and keeps time to within +10 seconds a day.


This is an incredibly elegant watch, rarely seen from Omega in this period. It is unusual in its mix between tank and cocktail design and the result is seriously impressive. This is a watch to be proudly worn on an evening or at dinner.
