The Orange & Gray Orca strap mixes subtlety with flair. It looks great with any watch with orange accents, particularly dive watches. The gray is a unique shade with very subtle tones of olive. As with all Orca straps, this one is made with thick 1.5mm high-grade ballistic nylon and stainless steel hardware. All BluShark straps are cleanly stitched around stainless steel hardware.
