Ok, here's how it is. I have a 1680 and 1665. Both of them are MBW-alikes, being picked up from that stall in Bangkok that supplies the guys that sell MBWs. They're both modded with gen parts and they're both fully working, which is important if you know that both 2836 movements had issues with winding and date changing stuff.
So, here's what's in them:
1680
Gen Crystal
Gen Crown
Gen Tube
Acrylic Pearl and modded insert (from Repaustria)
Pugged ( ) Crown Guards
1665
Gen crystal
Gen pearl
Ubi Datewheel
The 1680 was supposed to have a 2846 movement (the 2836 it arrived with was DOA) fitted, but I kinda ... um, yeah ... I pinged the winding ratchet spring across the room. I also tried one of Ubi's datewheels, but the magnification was a little high under the gen tropic and the printing was visible.
Anyway, I've taken a picture, but I've not got enough light for a good one. I hope this will do.
