I'm no expert, but I don't believe this band is an authentic Luminox brand product. I installed this on my Luminox today, and while it does fit, it does not fit nearly as snugly or securely as my old band. Additionally, it just doesn't have the same exact feel as the old band. It may be authentic, but I would suggest you do your homework on this product and be sure before you order. For this kind of money for such a simple watch band, the band should be authentic and fit perfectly.
