NOMAD, brand new, unused. Size compatibility: 42mm/44mm/45mm/49mm Model compatibility: Apple Watch 1-9/Ultra 1-2/SE Wrist size compatibility: 150mm—200mm Made of Fluoroelastomer/FKM This is the highly popular sports band, 【NOMAD Sport Strap Glow 2.0】 from NOMAD! The first Glow version sold out instantly, becoming a phantom band. The second version illuminates up to 3 times brighter than the previous one. The first of its kind, this band transitions from a classic pale green to an eye-catching glowing neon green when the light is off. High-quality FKM (fluoroelastomer) is used as the main material. It keeps the weight on the wrist light and has excellent oil resistance, chemical resistance, heat resistance, flame resistance, weather resistance, and ozone resistance. It is antibacterial and can be easily disinfected with soap and water. 100% waterproof. You can use it without any problems from hand washing to swimming. Three key points of the bold and sharp form, inspired by the appearance of diver's watch straps: Allows for more space against the wrist, ensuring high breathability. Increased flexibility makes it easier to wrap around the wrist. Overall weight reduction. The matte surface finish feels comfortable. The gentle concave curve prevents the band from sticking to the wrist during workouts or when sweating. Also, the back is designed for excellent breathability. It prevents water from hand washing or sweat from sports from accumulating on the wrist. The aluminum closure pin system (pin and tuck function) allows for quick and secure attachment to the wrist. This also solves the problem of the pin popping out of Apple's sports straps. With the NOMAD Sport Band, complete and secure attachment is possible.
