This is the second learning session on vintage Omegas. It is a rather common 1972 Seamaster with Cal 1020. It has day and date feature.
The case is stainless steel plated with 10 K gold. It is 36 mm width and looks correct with decent condition. The sign of wear is apparent. Lug is simple straight type.
The dial is yellowish silver in clean condition. The hands are stick type and their lume has worn off as expected for this age.

 

The marker has black insert that I guess is onyx. The marker at 3 o'clock position shows something missing.
There are no 'swiss made' writing at the bottom. Combined with suspiciously clean dial, I suspect the dial has been refinished. If it's true, well at least they do it neatly.
I try to find the details of this watch in Omega Vintage database but none come up.

The crown is still original. The case back is screw in type. However there are no typical Seamaster logo engraving in the case back. It's just plain with small writings " * 10K GFD BEZEL stainless steel back"

 

Herianto, do you know the quick way to tell the 75x series day/date calibers from the 102x series?

 

The inner of the caseback did not get perlage finishing. Both C 6357 and 8739736 does not help in identifying this watch.

 

When I saw the movement for the first time, I was confused, there is no caliber number and serial number!
I thought I buy a fake..................


However on closer inspection both the caliber number and serial number are printed in little circle with Omega name. Caliber is 1020 and serial number 35XXXXX confirming it came out in year 1972.



The condition of the movement is cleaner and better compare with my '62 Seamaster. No rusting except at the base of the screw that hold the movement to the case.

 

No sir......... would you mind to explain?

 

If there's a divider that separates the day from the date, it's a 102x. If there isn't a divider, it's the earlier 75x series.

 

I see ......... like this one below........

 

How about my suspicion that the dial has been refinished........is it true?

 

Thank's, I'll take closer picture on swiss made area at 6 position.
Interesting that watch maker differs their products slightly for each region. I guess it is similar with car company.

 

I've heard the Swiss is used where it was a local case, and Swiss Made where it was a Biene case?

 

Here is the closer look at the 6 o'clock position, still no Swiss Made writing ........... not even shadow of it. So I have to accept that this dial has undergone refinishing/ retouching or Omega came out with no 'swiss made' printing dial, which I think highly unlikely.





You can see that the minute markers are met with bezel side so no stepped down/ recessed area where the writing might hidden.

 

OK let me take another shot tomorrow. I'll try with 3 lamps to ensure the bezel side could be seen.
