Please help to identify this

[Veee]

Hi,
Last week I got my new Sterile Ceramic Bezel GMT.

After my first try on tweaking, it now runs quite
accurate ~3secs/day after it was way off.
(Pure luck it was.)

However, I wonder what kind of movement this is.
I was searching for more than 2 hours, but was unable to
identify the movement due to the overwhelming amount
of information, pictures reviews etc.

Can you please help?

Thank you very much in advance!

It looks similar but there is one thing I don't find in all other similar
movements I saw.
There is a toothed wheel close to the lever marked with an x.
(Actually the speed adjustment lever almost touched the toothed wheel
when I adjusted the movement for proper speed.)

I didn't find anything like that on the web yet.

I doubt that it's a DG1800 as it has a small second at 6.

Thanks for your help.

Try a DG3804B looks about like that from what i can tell in your pic. They are very common in GMT's
