Hi Gary   Whats the caliber number of the movement   ebauches denoted by the outer design and AS as stated by J Berry. I have a list of symbols someware if you would like a copy  They are also listed in the Bestfit books.   cheers mate

Yer

No cal number just. This as at in a cloud. 

It's not in the bestfit books I have searched. 

And if it is the one jberry says I'm in trouble cos it keeps great time but if I put it on timer machine it's minus 359 with lift angle set at 52 deg. 

Most Oris are 38 deg to 44 deg. 

So l am still confused. 

Cheers

Gary

In the third pic, it looks like there's a number under the symbol ?

Hi Gary  If and when you get the Cal number post it up the lift angle is movement specific  you could have two Oris watches with different movements both with different lift angles.  Try chaning th Lift angle and record the difference

Yer it's not a in house Oris I am sure as says schilf but no asat

As @JBerry states above, the ST stands for 'Standard'.

It's an AS 1950/51 movement. I have the same movement in a Royce watch.

The lift angle is 52 degs

Also, lift angle doesn't affect the calculation of the timing if it's that what you're refering to with "minus 359", it's only relevant for amplitude.
