Anyone else done this? The M5600BC is a hard to find one and I already had the regular M5600 and the original band to it broke so I called Casio parts and ordered the band and spring rods (they're a tad skinnier I can tell, so I'm glad I ordered those too) from the BC model. They had some available but they weren't cheap but I got it anyway and I really like it. As far as compatibility it seems to fit fine but is the dimension of the watch head and fittings of the regular vs. the BC version exactly the same? Just trying to make sure it is indeed a truly compatible fit for this expensive watchband.
