Good evening,
Sorry if I'm in the wrong section but I wanted to ask if there was anyone who could help me identify the movement because even after days of searching on the forum and on Google I didn't find my answer.
I basically have this GMT 2 Batgirl in my hands which basically:
Position 0 = Crown screwed on
?
Position 1 = crown unscrewed
?
Position 2 = if I turn clockwise it changes the date, counterclockwise it only moves the GMT hand with audible clicks
?
Position 3 (crown all the way out) = time adjustment, (all hands including the GMT one move both clockwise and anti-clockwise.

I haven't seen anything like it so I hope you can tell me what it is..
The watch itself has more or less 3 days of charge from my tests, I wound it on a Friday at 7.30pm and today Monday at 7.20pm it was still running.
