Art Deco 1935 9ct Rose Gold Rotary tank watch, shockproof recently serviced ETA.


This is a beautiful Rose Gold tank watch, with is all the more wearable with it's shockproof movement. This was uncommon on any dress watch, or watch in 1935.


The watch is marked by Glasgow assay office with the date letter M, putting its age to 1935/36.


This watch is incredibly well preserved all around and has many finer details that make it very desirable and great value for money.


 The rose gold case was relatively uncommon in 1935 and provides a very appealing tone, to offset the silvered dial nicely. The contrast would have been less subtle if a shade of yellow gold was used.


The case is interesting as it is quite angular, not just a plain rectangular case. This would have been more difficult to make, with it's faceted design at the top and bottom of the case, consisting of 3 different faces. This creates a great texture to the case and appealing angles from either side or straight on, as the light catches them.

This is also seen with the angular design of the lugs contrasting with the long straight sides.


The crown is also recessed into the side of the case, disappearing almost and not hanging over the side. This is a real indicator that this was a carefully designed dress watch, aiming to be subtle, yet classy.


The dial is very interesting with a silver box framing the Arabic numerals. This is unnecessary, but shows the time and effort to create a pleasing watch, with carefully considered elements.

The Arabic numerals are in an Art Deco inspired "Egyptian" font, which is rarely executed so well on the dial.


Overall this is an incredibly impressive watch, which is very wearable and sits nicely on a wrist around 7 inches. All I can say, is try to find another vintage 1930s dress watch like this. Utterly classy.
