Sport band for Apple Watch 38 40 41 42 44 45 46 49mm

This new sport band fits Apple Watch models from Series 1 through Series 11, SE 1 through SE 3, and Ultra 1 through Ultra 3. It is sold in a black and grey colour combination. The band is designed for men and women who want a single strap that works across multiple case sizes and generations.

Limited to Apple Watch lug width and clasp mechanism

The band uses the proprietary Apple Watch lug interface, so it cannot be used with any other smartwatch brand or traditional watch spring bars. Compatibility depends on selecting the exact case size that matches your watch model; an incorrect size will not attach securely. No adapters or alternative fastening methods are included.

Soft silicone with moulded air holes

The strap is made from soft silicone that resists sweat, dust and odour while remaining flexible for daily wear. Moulded ventilation holes run along the length to improve airflow during exercise. The pin-and-tuck buckle secures the band with a flush profile that sits flat against the wrist.
