Seiko SEISB415P Black Steel Watch Band Fades Repeatedly

I purchased a Seiko SEISB415P black watch, but the band’s color has started fading quickly. I sent it in for warranty service, and it took a month to get it back. Although they claimed it was fixed, the band’s color began fading again shortly after. For a brand like Seiko, I expected durability and quality, especially from a black steel watch. This recurring issue with the color fading is frustrating, and I am seeking a permanent solution to prevent further fading. Seiko, please address this defect urgently so I can enjoy the quality I initially trusted in this watch.
