There is a speedy on C24 that looks suspicious to my untrained eye.
The color of the movement looks too "rose gold," and the markers look almost highlighter yellow instead of the darker / creamy patina I have seen. Can anyone with more experience chime in?
For the record I agree with Davidt (who knows far more that I) that dial and lume are good. Nice looking watch good luck with purchase if you are inclined. What does caseback look like? nice writing and Seamonster logo? Another clue that its -76is the plastic chronograph brake part, which is the hockey stick shaped yellowish part above the E on Omega, I believe that the -76 is the first year that part changed to plastic.
I may well be mistaken regarding when Delrin brake appeared may have been earlier - MWO refers to this on later production of the Straight writing ? 1973?
