KSwatches, is this the same watch you have above?

If so the movement they listed as A3187, and the dial feet is the same as gen? That is very interesting. So BP and NOOB SA3135 will fit gen dial, hands, and DW. I am assuming you have to sand down the DW to fit the rep movement. Sorry for asking a lot of questions, but I never own an SA3135 before, and I have no clues will my gen dial with be fit for this mod. I owned ARF 116613 LN previously and had the local watch smith to installing the Gen 3135-105, 3135-110,3135-118, 3135-130 and 145 (complete automatic device module). The movement work like a charm but I sale the watch because of the gold color!
