RECON-01 | 5.56 NATO BRACELET

Purpose-built from repurposed 5.56 NATO brass, Cerakote Armour Black and Atwood 275 paracord.

Handcrafted by British craftsmen each bracelet uses a repurposed 5.56 NATO brass cartridge case, individually acid-etched to create its distinctive textured finish, coated in Cerakote Armour Black, and threaded with durable Atwood 275 paracord. On occasion, where 5.56 cases are unavailable, equivalent .223 Remington brass may be used.

Made in small batches, each piece carries subtle natural variation in the brass and etched finish, giving every bracelet its own character while maintaining the clean, considered CALIBR aesthetic.

ORIGINS

Calibr.UK was built on a simple premise:
make fewer things, and make them properly.

Founded by British craftsmen, Calibr.UK is built on experience — shaped through years spent working with materials and refining the way things are made. It’s an approach grounded in doing things properly, where nothing is rushed and durability is expected as standard.

All pieces are made in the United Kingdom, in small batches, with production kept close and deliberate. This ensures consistency from raw material through to the finished piece.

Each stage is defined by precision, with a clear focus on refinement, consistency, and longevity.

From early experimentation to a more considered approach to design and making, Calibr.UK continues to evolve — guided by intention and a respect for the craft.

It exists as a continuation of that approach — built on experience and driven by the pursuit of better.
