Good Morning.
I would like to know if is possible to have this dial on a 145008 from the seventies.
I’m In doubt For the use of the third button with this dial...

 

This is the non-rotating bezel of the 145.007 and this bezel is not correct for this reference.

The Omega Chronostop 145.008 has come with one of these four different bezels:

 

I have never owned one so cannot say definitively but have never seen the third button combined with the tachy scale. Only seen it with the inner rotating 0-60 bezel.
Having said that I see your tachy bezel doesn’t line up 60 with 12o/c so I assume it is rotating but not sure why

 

I totally agree with u.
I dont know how i have to rotate a tachy scale. So i think wasnt correct.
I’ve found this watch and i was thinking to buy it. buy i want to know what i have to change on.
and i suppose only the tachy bezel.
It has been strange to find the bezel aged like the dial and the watch...so i’ve thinked it could be i possibility i didn’t known
