Problem with these 1655 reps is mainly that the rep-crystal is made for 1680/5513 cases so when one is trying to fit a gen 1655 crystal it's to wide. It took me forever, using special glue and o-rings to fit it =(
Also I think the lume on most rep hands are too wide compared to the gen, wished they'd fix this too =(
The MBW 1655 probably has exactly the same problem as Trustys 188$ one
