Introducing the A01 Case for Apple Watch Ultra by aulumu — where minimalist design meets functional protection.

Choose between two top covers: genuine carbon fiber or aerospace-grade titanium, both paired with a premium FKM band. Built for those who navigate the city with intention — sleek, durable, and unapologetically personal.

The carbon fiber version is precision-crafted using multi-layer compression molding, giving every piece a one-of-a-kind weave. Nearly weightless, yet engineered to protect with bold, technical character.

The FKM band is soft against the skin, breathable, and resistant to sweat, water, and UV — perfect for daily wear, from workouts to weekends.

If you’re drawn to futuristic aesthetics and subtle individuality, this setup was made for you.

Carbon Fiber for top cover
