2x 50mm and I3 50mm straps are not compatible.

Just a heads up really. I wanted the change the rather dull gray strap mine came with, so tried two different 2x 26 straps.

While the straps are identical in size and shape, the pin holes in both were slightly further back from the watch, (almost 1mm) and even with some force I can't get the pins to sit in place.

Has anyone tried/found any other straps? 

Thanks

James
