I bought a Batman rep in Shanghai several years ago. I think I paid around $300 for it. Back then I wasn't really into the details, but lately I've become curious about which factory this GMT-Master Il might be from.
The clasp code is P3L and the serial number is ER6J5350. I vaguely remember being told at the time that it was from Clean Factory, but I haven't been able to find any information matching the clasp code or serial number in the google doc.
I barely wear the watch these days, but purely out of curiosity I'd love to figure out which factory made it. Is it a shitter by any chance?
Edit: Lerch87 found the correct factory (EWF)! In case someone in the future has the same question, some EWF models seem to start with the serial number ER6J.
