Chris -
No, we do not replace the
straps for you here at Niche. There are no directions that come with the replacement
band, but your jeweler should have no problem figuring it out. The main problem is that you pretty much need a special tool to do the replacement. Jewelers have it, and can do in a few minutes what might take you or me the better part of an afternoon.
Hope this helps.
