The Dux Ducis OceanWave in dark blue is a specialized silicone strap designed for Apple Watch users who lead an active lifestyle. Its distinctive cylindrical cross-section with a ridged, wavy design makes it highly suitable for water sports such as surfing or diving, as the material is naturally water-resistant. To ensure durability in wet environments, the strap features a rust-resistant stainless steel buckle. It is designed for a simple click-in installation using standard Apple Watch connectors, making it easy to swap between different styles. This specific model fits 42mm, 44mm, and 45mm versions (Series 2 through 9 and SE).
