Premium titanium magnetic buckle meets breathable nylon design with one-step quick release for all-day comfort and secure wear.
AULUMU, a design-led accessories brand focused on precision materials and functional innovation, today announced the CS03 Titanium Mag Buckle Quick-Release Band, a precision-engineered strap created for Samsung Galaxy Watch Ultra users who want a refined balance of durability, comfort and effortless everyday usability. The CS03 builds on AULUMU’s growing reputation for material-driven wearable design, pairing a titanium alloy magnetic buckle with a breathable high-density nylon weave to deliver a strap that feels as premium as the device it attaches to.
The CS03 introduces a simplified approach to daily wear through AULUMU’s magnetic quick-release structure, enabling a fast one-step attachment and removal process without the need for repeated adjustments. This convenience-led design reflects the evolving expectations of smartwatch users who increasingly prioritise accessories that adapt seamlessly to work, travel and fitness routines. Once sized, the band snaps into place with a clean magnetic alignment and removes just as easily, supporting a smooth transition between activities throughout the day.

At the centre of the design is a titanium alloy magnetic buckle engineered for strength while remaining noticeably lightweight on the wrist. The buckle features a scratch-resistant coating for long-term durability and is paired with a dual-secure fastening system that combines magnetic locking with a hook-and-loop layer for added stability during movement. This structure ensures the band stays reliably in place during runs, gym sessions or daily commuting while maintaining a soft, comfortable feel against the skin.
The strap is constructed from high-density nylon chosen for its breathability and soft-touch texture. The material promotes airflow and reduces moisture build-up, making it suitable for extended wear in warm conditions or during high-intensity activity. Its flexible weave allows the band to contour naturally to the wrist, supporting a more personalised fit that remains comfortable from morning to night.
AULUMU includes both long and short strap options in every CS03 package, offering a broader wrist-size range without requiring additional purchases. This dual-length approach enhances usability and ensures a more tailored fit straight out of the box. The connector is engineered with a precise 1:1 fit for Samsung Galaxy Watch Ultra models, maintaining a seamless visual integration with the device’s industrial aesthetic
The launch of the CS03 reflects continued demand for premium materials within the smartwatch accessory category. Titanium’s strength-to-weight ratio and resistance to corrosion make it an increasingly popular choice for users seeking a more refined, long-lasting upgrade over standard silicone or stainless steel bands. By combining titanium hardware with a performance-focused nylon strap, AULUMU positions the CS03 as a versatile option that bridges everyday comfort with elevated design.
The AULUMU CS03 Titanium Mag Buckle Quick-Release Band is available now in Black and Titanium via the official AULUMU website and Amazon for $59.98. It will also be available on Amazon UK from May.
