Hello to all,

would this be the period-correct crown for a 145.022-69ST ?

Diameter = 6.5mm. Thickness = 3.3mm

 

I have the same crown on my 145.022-69 with a 29.1m serial movement. The watch was never serviced, so it should be right
Here is the pic of mine. After close inspection, it doesn't look like the same crown.
I don't have my MWO book with me...

 

It doesn't seem the right 1969 logo to me.

 

Iircc I have the same crown on my -69, and it's an omega replacement.

The logo should be smaller, like in @MaiLollo 's watch is the correct, smaller logo crown.
Can't verify right now as the speedy is in the bank vault atm.

Cheers,

Max

 

For me this is the correct crown for the -69.



This one is on an early one, 29 Mil serial.

 

Interesting... someone got MWO handy?

 

Here is a pic of my crown that I am fairly certain is factory original. serial 30584xxx. Looks like mailollos.

 

Please correct me if I'm wrong, but doesn't the number of teeth also help determine which is the correct crown?

 

Anybody?! Mine's at home...

BUT

I have the MWO electronic guide on my phone...

Both should have 24 teeth.
Narrow Angular feet : 145.022-69
Wide Omega : 145.022-69

Edit : I would post screenshots, but don't want any copyright infringements...
So, @Frederic_gva , it would appear yours is correct, as well as @MaiLollo et al

 

Thank you all

 

Hello,

Sorry to hijack but my crown looks different from either @MaiLollo or @kov so I am guessing it’s a replacement crown.

Is my assessment correct?

 

To me yours looks like kov’s/frederics. Could be that their macro lenses distort the shape slightly...

 

Exactly the same crown, indeed.

 

For at -69 it should feature 24 teeth and according to MWO both can be correct like @MaiLollo and @kov . The most round logo version is introduced in 1970.
The narrow one from 1970-72(?). I have a -71 from Nov 1973 with that one fitted.
