At aulumu, we’re committed to reimagining everyday tech accessories through the lens of advanced materials and minimalist design. Our latest release — the aulumu A01 case and band for Apple Watch Ultra — is a perfect example of that vision. It’s not only our first aulumu Apple Watch Ultra case to feature aerospace-grade titanium, but also introduces a stunning carbon fiber case variant that we’re especially proud of. The aulumu case collection continues to push the boundaries of performance and aesthetic design.
What Makes Carbon Fiber Special
Carbon fiber is a high-performance composite material widely used in aerospace, automotive, and high-end sports equipment. It’s prized for its:
Incredible strength-to-weight ratio — stronger than steel, yet much lighter
High rigidity and durability — ideal for protective gear
Resistance to heat, corrosion, and chemicals — built to last in challenging environments
Technical texture — minimalist, modern, and premium in appearance
Non-conductive and non-magnetic properties — suitable for tech-integrated accessories
In the A01 watch case, we use real, hand-laid and heat-pressed carbon fiber, ensuring that no two pieces are ever exactly the same — each one is subtly unique in its finish and structure. This advanced manufacturing process not only preserves the material’s integrity but elevates its visual appeal and durability. The result is a featherlight yet incredibly robust A01 Apple Watch Ultra case that feels as premium as it looks.
Why We Chose Carbon Fiber for the A01 Case
We selected carbon fiber for the A01 case because it represents everything we stand for — durability, precision, and minimalist beauty. It offers Apple Watch Ultra protection without adding bulk, and its refined appearance, achieved through meticulous craftsmanship, complements the clean geometry of this minimalist A01 watch case and band. It’s one of the signature aulumu cases designed to meet the needs of modern wearable tech users.
Thoughtfully Engineered for Everyday Wear
Beyond the materials, every element of the A01 band and case is designed with comfort and performance in mind. The skin-friendly FKM strap offers a soft, flexible fit that remains comfortable against the skin throughout the day.
A custom aluminum closure pin ensures a secure fit, while aluminum buttons are precision-engineered to be fully compatible with all Apple Watch Ultra controls — making this an ideal carbon fiber case with aluminum buttons.
The A01 watch case itself is crafted from durable polycarbonate with a multi-layer spray finish, offering full coverage while maintaining seamless access to speakers and sensors. Sized to fit most wrists (170mm to 205mm), the aulumu Apple Watch Ultra band is designed exclusively for the Apple Watch Ultra 1 & 2 (49mm) — making it a truly tailored A01 watch case and band solution.
Where Else We Use Carbon Fiber
Carbon fiber is one of the defining materials in our product lineup. Beyond the aulumu A01, it’s also featured in our aulumu G03, a minimalist aulumu wallet designed for portability, protection, and style. The aulumu magsafe wallet offers three distinct cover options to suit different preferences, including a carbon fiber cover variant that combines lightweight durability with sleek aesthetics.
And we’re just getting started — future releases will continue to explore carbon fiber case solutions in even more versatile and innovative forms.
