UNDONE Aquadeep Carbon Manta: A Carbon Fiber Dive Watch That Protects the Deep

Some dive watches are built for the ocean.
This one is built for the ocean.

The UNDONE Aquadeep Carbon Manta is a forged carbon dive watch inspired by one of the sea’s most majestic creatures — the manta ray. Powerful yet graceful, it transforms deep-sea motion into mechanical form, balancing professional watchmaking with real conservation impact.

This is not just timekeeping.

It’s a mission on your wrist.

Inspired by Maggy: A Manta Ray from the Kuroshio Current

In the vast Pacific, manta rays move like underwater dancers — silent, elegant, unstoppable.

The Aquadeep Carbon Manta takes its inspiration from Maggy, a 5.5-metre male manta ray tracked in Japan’s Kuroshio Current. In 2025, Maggy became the first male manta ray in the region to be successfully satellite-tagged — a milestone in marine research.

That story became the soul of this watch.

A Watch with Purpose: Every Piece Supports Conservation

This model marks a formal collaboration between UNDONE and The Manta Trust, including its Japan division.

Impact that matters:
 • A portion of proceeds from every watch sold
 • Directly funds manta ray research and habitat protection
 • Supports satellite tracking and community-based conservation

Wearing this watch isn’t symbolic.
It’s active participation.

Design Language Drawn from the Ocean

Every design element traces back to Maggy’s movement through the sea.

• 90g forged carbon fiber case

  Ultra-lightweight. Exceptionally strong. Built to move like a manta ray underwater.

• Laser-engraved wave dial

  Each pattern mirrors the breathing rhythm of the Kuroshio Current.

• UV-hidden manta motif

  In darkness, a luminous manta ray appears — quiet, unexpected, powerful.

• Custom rotor engraved with Maggy

  Every movement of your wrist sets the manta in motion.

Nothing is decorative.

Everything has a reason.

Professional Dive Performance — No Compromises

Romance alone isn’t enough.

This watch delivers real capability.

• Japanese NH35A automatic movement

• 300 metres water resistance

• Built for actual underwater use, not just aesthetics

It’s a dive watch you can trust — whether you’re underwater or navigating daily life.
