"1927 art deco rectangular Omega in steel. T17 movement. Almost mint throughout. Even the original movement dust cover is still here. "

(these are all the images I have- none of movement)

thoughts? all advice welcomed, including ideas of value (priced at ~£1800).

 

The first thing I see is a refinished dial. The quality of the printing is low. Moreover, these watch were not sealed very well from the environment, and you can see there is a lot of grime inside the case, around the stem, etc. So with all this exposure, you should expect evidence of this on the dial, which is lacking in this example.

 

That's a CK 730, but the dial really looks repainted. Moreover the date mentionned by the seller is wrong : there is bo such thing as a 1927 T17. This caliber was created in 1934.

 

Dial is certainly refinished (not perfectly btw), hands are either replaced or restored, case is polished. It also seems to be from late 1930-s not 1920-s. Would be interesting to see the movement.
