The movement is in the 33mil, therefore around 1971, although the dial and inside case back (145.022-69ST) date it to 68-69. Can someone shed some light, and am i just being paranoid? any insight would be greatly appreciated!! Thanks
What concerns me is the movement for this dial and caseback should be around 29-31mil, and this movement is stamped 33 mil. Is this possible, or was the movement possibly changed at some stage? Possibly during a service
The Speedmaster serials are slightly out of phase with the rest of Omega's serial numbers so this chart is more accurate: http://www.chronomaddox.com/romans.html
Thanks Dsio. So then the movement and case cannot be matching if the movement is 33mil, which on this table dates it from 1975! And the case stamped 69 ST was use in 1969-70.
