Compatible for OnePlus Watch 3 Bands, Sports Silicone Band Strap Replacement Wristband Compatible with OnePlus Watch 3, OnePlus 2 46mm / 2R / 1 Smart Watch

The strap feels and looks good but the connection pins to the watch casing are shorts & smaller in diameter than the genuine straps & look weaker, I don't think I would risk using the strap, especially if swimming with the watch. Green strap in the picture is genuine.
