I bought a few of hour/minute hands from a well known online store matching the hole diameters for an NH36 movement. However the minute hand is always loose. I went back to the minute hand that came with the watch and it fits and works fine. I contacted the seller and they insist that the dimensions are correct but the item might need "minor adjustments".The hands aren't very expensive so I'm ok experimenting, but I have two questions:- Is this actually common to have to do? I have ordered 3 sets of hands from this seller with the same results.- How do I actually accomplish this? The hands are so delicate. Clearly I'm supposed to press the flange in somehow. Just some minor pressure from pliers?
