Omega Seamaster diver caliber 565
After the wait, finally I received my Omega Seamaster diver watch with caliber 565. It is indeed attractive, since the patina, on the hour markers, hands and bezel insert, is gorgeous and even, throughout.
I would like to know, as to the reason why the dial is marked only 'Seamaster' (though I prefer this) and not 'Seamaster 120' or 'Seamaster 300', as commonly seen in other vintage Omega Seamaster diver watches of the 60's and 70's.
The dial is perfectly factory-original and had not been reconditioned or refinished. In short, untouched.
Herewith, is the picture of this watch.
Thank-you

Thanks for the response. Your watch has an interesting dial and I have not seen any of this around. Usually, such depth-rating is found only in the very old Submariner watches. I am sure you love your watch and it will have lots of wrist-time. Thank you f...

lovely condition, great patina on dial and hands, screwdown crown and case as per the 166.024 so it is possibly 200m WR. i've never seen one without a '300', '200' or '120' on it, but never say never when it comes to vintage omegas. enjoy it Graham
You are correct

Thanks for your response. I agree with you. I have just realized, all watches with this type of dial, model reference 166.073 (rectangular tritium) come without the depth rating, while all the others that come before and after this model reference, have t...

Thanks for the response and also, those kind words. I am happy with the watch, since it is not only attractive and solid-looking but its price is only a fraction of that of the high and mighty popurlar vintage Submariners. Thank-you.
