I have sized my own bands on many watches. but this oris aquis is something else, its like the the pins are soldered in. I started with taps, but eventually i got big hammer hit with some might and my push tool would bend but the band pin doesn't budge. I start hit the round side of the pin (not the screw looking side) but than i turned over and tried other size.. tried other links. damn thing will not come out. what am i missing here?
