Some watch bands are accessories. The Shark is a statement. Built from genuine FKM Fluororubber — the same fine watchmaking-grade material used in timepieces costing thousands — The Shark delivers a wearing experience that standard silicone simply cannot match. Silk-soft against your skin, yet engineered to withstand heat, oil, sweat, and the demands of daily life without degrading, stretching, or attracting lint. At its heart: a luminous great white shark emblem, custom-printed with high-grade glow-in-the-dark pigment. Charge it in sunlight. Own the dark. Secured by a precision-machined 316L stainless steel butterfly deployment clasp — the same closure found on luxury dress watches — The Shark locks onto your wrist with a satisfying click and stays there, whether you're in a boardroom or underwater.
