Help on identifying a movement

[east3rn]

Hello. I am working on a vintage piece but I could not find the name(ref no.) of the movement.

Could anyone tell me the name of this movement?? All I know is that it has "AS" written on the mainplate.

Thanks!

Hello.
Cannot identify it myself.... But check out the advanced research on the Ranfft database. It should help you.

Sorry I cannot make the research myself now.... But I am looking forward to reading more.

wow this has me stumped. i work on swiss trench watches too and AS is very common. I always see Calibers 168 and 137 occasionally a 158 but i have never seen this one. its reminds me of a cyma or tavannes cyma (TACY) movement, but it is clearly AS due to obvious logo and keyless works

A.schild 625 I think also used by gruen as the 771 listed in best fit page 145 as a 13 ligne 771 is this quite a large size watch because the movement would be 29mm across if it is a 625

does anyone have the bestfit encyclopedia 111?

625 seems a little different from the movement I have.. but I should definitely search near 625 movement. Thank you for your advice!

They do look similar but there isn't one that exactly matches with the movement. Thank you anyway!

Oh may be this is a rare one...which also means it would be difficult to find spare parts
