Hello everyone

I am wondering if this an all original Omega head and not redone. Except for the crown, I think everything else is correct. Serial dates it 1962. Caliber 600 and case number 135.020.
Would like to seek your opinion please.

Yes, the watch is correct, except the crown. I can't tell you about the bracelet, as I have not seen one of these before. I would look for a gold plated 7-row BOR. To me the two-tone does not pair with the case style.

Everything looks authentic but I’m not sure that movement belongs in a De Ville. The 600 series of movements belong in these watches...

Oh, good catch! I completely forgot the printed 600 on some of these Omegas. I'll research further. Thanks for the heads up!

I have a 1961 seamaster with a 600 movement but no "600" on the dial.

And the plot thickens! Would highly appreciate a photo sir, if you have the time.

It’s not a De Ville though, some of these “600” watches did not have dial marked but were same style. Similarly there were some De Ville style Seamasters without De Ville on dial.

here it is - model 14759-SC-61 with a cal 600 movement

Your watch, like the 600 models has a screw on case back, as where the De Ville models had a fixed case (back doesn't open)...the movement came out through the front/crystal. IMO the movement in OPs watch didn’t start its life in that case.

I can't comment on that and I bow to your superior knowledge! Mine certainly has a screw on case back as you say. When were the De Ville models introduced?

Omega used the De Ville moniker on the Seamaster from 1963 to 1967. I have a 1963 Seamaster De Ville and a 1964 Seamaster 600, pictured above. The De Ville is an automatic movement (cal. 552) and 600 is a cal. 611 manual wind (as all 600 series were). The De Ville name however is still used to this day, in fact I also have a 1968 De Ville Chronograph with a cal. 861.

So the cal. 600 is correct for the watch, and not all vintage Omegas with cal. 600 should have the 600 printed on the dial? 😀
