Hi does any one know who this mark is for . i know AS is schild but cannot find ASAT see pics.

Its a oris and under the mark its got 1950/51.

I am trying to find the lift angle to time it. before i strip it.

thanks

AS ST Seems to stand for AS Standard, if this is your movement: http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&0&2uswk&AS_1950, Then Lepsi lists the lift angle at 52

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

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

Hi Gary have a look under the balance rim below the symbol, Mikepilk is right there looks to be a foru digit number.

[gary17]

The number under the marh is 1950/51

This is not an Oris in-house movement.

AS ST lists the lift angle.

[gary17]

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

[Nucejoe]

Look up AS and ST and AS ST lists.

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.

Hi  Gary    You are getting plenty of info off the members so I won't interfere. Tech sheet attached.   cheers mate

You might also like to take a look here -> https://17jewels.info/movements/a/as/as-1951/

The one you have looks filthy and I would also suspect from the position of the balance regulator components, that it is out of beat and running slow.
