This is a vintage movement and I am just curious can anyone identify what movement is this?

 

Any markings under the balance wheel?

 

alas i didn't look. case back is unmarked as well :/

Could this be a preseux

 

Looks to me like Unitas 6497. But that movement is for pocket watches because it is 16.5 lignes in diameter. Image fro the Ranfft archive.

I doubt it is the 6497.
Maybe an AS of some sort.

 

Looks as though there is a number stamped into the plate beneath the rim of the balance wheel, at about 3:00 in the above picture. There is also likely a maker’s trade mark by that number. Need that info.

In my first reply, I wrote “looks to me like Unitas 6497”. Well, it does resemble the Unitas movement. I also referred to the fact that this movement is normally used in pocket watches because of its size. With nothing to compare for size in the photo, who knows. It may be a 6497 re-cased in a wrist watch case, which apparently is a conversion often done. Need more info from the OP.

 

Google watch movement database and look at AS movements withat that number first under the balance. Then Unitas. Then open up the mfgs.

The database is pink.

 

You are right, i will see when i can get it to a watchmaker to open it up again, although I'm cautious against moving any parts to reveal the number

 

Looking at the bottom half of the logo, it could be several things.....

All the same, one is a different size. but all from the same family, I can drive it down more if you showed what was on the other side. Basically its a Perseux based movement that was licensed either a 320 or 330

 

Good call. Mysteries like this drive me crazy.

 

Definitely not a 6497 - click, crown wheel, and pallet bridge stand out as very obvious differences to the 6497, plus other more subtle differences. In addition, the layout of the movement is completely wrong for a 6497, which has the small seconds opposite the crown, so would be at 9 o'clock on a wrist watch where the crown is at 3. This watch has it at 6, so if it were of that family, it would be a 6498...

It's a Peseux of some kind as noted. ETA also makes a version of this now known as an ETA 7001...here is one where you can see the similarities:



Without knowing the size it would be difficult to pin it down much more than that though.

Cheers, Al

 

That is when a Ligne gauge comes handy.

 

Alright I'm gonna reveal a big clue: this is a movement inside a vintage Sarcar watch
