This is a 165.001, as it has no bezel. 165.002 is nearly identical, but with a separate bezel.
This watch was manufactured after the switch to tritium, but before the Swiss standardized on the T mark on the dial. The tritium lume with the lack of a T on the dial places the manufacture date between 1962 and 1963.
Lifting a digression from another post, but why do so many Omega Tritium dials not have a T.
Taken from the Moon watch only site
'The T indication only appeared in 1964 following a Swiss interior ministry ruling from October 1963 on radiation from luminous watch dials.
It required indication of the presence of radioactive substances and set forth a table of radiation limits, which came into force on January 1, 1964.'
IMO the lume dots are not the size, shape or color that one would expect to see for the original lume on a watch of this era. Again, not a big deal.
Well good luck, I agree with Dan about the relume.
Rotor rub?
What did you pay?
No service marks in the case back, possible this watch has never been opened up before today.
