The slimmed down version of our AlphaShark luxury nylon watch strap, inblack with a thin red stripe. Crafted from high tensile strength "seat belt" nylon, the AlphaShark Slim is only 1.2mm thick. The nylon is extremely soft and pliable and it is adorned with premium hardware including a sliding keeper. If you love the AlphaShark, but would like something with a lower profile, the AlphaShark Slim is for you. It's a great option for watches with little clearance between the case and spring bars, like many Rolex models.
