Expose the Core.

A Mechanical Watch That Reveals Its True Heart.

The beauty of a mechanical watch isn't found only in its finished appearance.

It lives beneath the dial.

In the intricate movement of gears.

In the steady rhythm of the balance wheel.

In the silent energy released from a wound mainspring.

That hidden mechanism is what gives a mechanical watch its soul.

AXIS was created to reveal it.

Rather than concealing the movement behind a traditional dial, AXIS brings it into the spotlight through its distinctive center-open design.

Not simply to showcase complexity—

but to celebrate authenticity.

This is mechanical watchmaking, exposed.

A Mechanical Watch That Reveals Its True Heart.

The Heart of the Watch Comes First.

Many watches are designed from the outside in.
AXIS was designed from the inside out.

We began with the movement itself.

Every curve of the case, every index, every hand, and every opening on the dial was carefully designed to highlight the beauty of mechanical engineering.

The result is a watch that doesn't simply contain a movement—
it celebrates it.

Because the movement isn't something to hide.

It's the reason this watch exists.

MIYOTA Cal.90S5 movement 

Rather than choosing a movement to fit an existing design, we started with the movement itself.

The Miyota Cal. 90S5 became the foundation of AXIS.

Its slim architecture made it possible to achieve the proportions we envisioned, while its open layout perfectly complemented our center-open dial concept.

Every design decision—from the shape of the hands to the placement of the indexes—was made to enhance the visual depth of the movement beneath.

This isn't simply a watch powered by the movement.

It's a watch designed to celebrate it.

Sapphire crystal & inner index

Contrast between metallic white dial with white printing inner index reflects a shaded expression. It maintains reliable and reassuring image with dressy appearance, allowing you to be yourself and add a touch of glamour. It is recommended for those who seek nonchalant atmosphere even in business settings.

SUS316L stainless case
