Today I received my new Luminox Men's F-177 Niighthawk Watch 6402 BLACKOUT. Purchased through Amazon. The watch was a little loose so went to adjust the silver pins in the clasp as I only needed a little slack uptake. When you place the pins in the first hole (read the tighter adjustment hole) the clasp wil NOT allow closure. For such a reasonably expensive watch the stainless steel band cheapens the watch. I removed a link in the band and noticed what others have stated in their reviews, the pins are weak and seem to be somewhat undersized as they slip back into place too easily.
The watch seems to be a good looking one, solid and readable in day-light. It is heavy but not so you will notice after wearing it for a half hour. Luminox waxes lyrical on its final review of each watch for workmanship etc., not so, for reasons stated above. The watch band is not adjustable using the obvious adjustment options available.
It should also be noted that the Seller warrants this watch, not Luminox, because the Seller is not an authorized Dealer, hence the Luminox warranties do not apply. This is an important provision not pointed out in any text. The watch actually comes out of China but seems to be an Authentic Luminox none the less.
