Help! What movement is this?

[sssurfer]

I just got a PAM 287 rep, disassembled it, and to my surprise it did not come with the usual DG 3809 movement but with an unknown movement (unknown to me at least).

Movement diameter is 30.35mm (DG 3809 is 25.60), thickness 7.15mm (DG 3809: 6.10).

Datewheel diameter is 24.6mm (DG 3809: 22.95).

Here are a few pics. The three-screws rotor might qualify it as a Seagull moevement.

Does anyone know what it is?

Thanks in advance,

:sss:

Based upon the rotor, and the plate directly below it, it appears to be almost certainly a Seagull movement...Except for the single suspended escapement, it appears almost identical to the 25-30's in my 090's...And you can see where this same base plate would exactly fit with the 25-30 double bridged escapement configuration...The swirl decoration on the plates appear to be exactly like the Seagull's too...So this appears to be a fairly robust well put together piece... ;)

Really thanks for your expertise, Frank!

I too think this may be a cousin of the 2530.

Actually, it's almost as thick as the 2530: 7.15mm vs 7.40 (a difference that might be due to the lack of the PR module).

Hand sizes are exactly the same: hour 1.5mm, minutes 1.0mm (but those are also the same of DG XXXX movements).

Diameter is very similar too: 30.35mm vs 30.40mm.

The main difference in dimension is that of the datewheel: 24.6/18.4 vs 27.1/20.8 of the 2530 (ext/int).

Ok, I'll keep hunting on the Seagull path...

I would say seagul too due to the rotor but cant find and reference to base it on

This looks very similar if not the same as the movement in the Asian Chopard GTXL

Thanks all for your help, guys!

If you ever happen to stumble upon any further info about it, please lmk.

Yes, Asian Chopard GTXL:

Anyone find out what model number this movement is?  I have one I need a stem for.
