ChronoAstra × Sandry Riffard watch with a blue stained-glass enamel dial — Prototype shown · each finished dial will be unique

THE COLLABORATIONLAUSANNE × THE WORLD

Tattoo becomes architecture. Architecture becomes light. Light becomes time.

Sandry Riffard is known for hyperrealistic tattoo work that folds gothic architecture, cathedral windows and dark imagery into the body. His compositions feel precise yet alive, controlled by line and transformed by color.

For ChronoAstra, that language leaves the skin and enters a physical object. The same organic black structure is rendered in precious metal, surrounding translucent enamel that catches and returns light like stained glass.

The artist behind the dial

Sandry
Riffard.

Sandry has built an international following through hyperrealistic tattoo work that merges gothic architecture, dark imagery and the luminous geometry of stained glass. For this collaboration, that unmistakable visual language is translated into precious metal and fired enamel.

The ChronoAstra perspective

Eight years of experience,
built into one watch.

Over the past year, ChronoAstra founder and lead designer Raven Reichl worked in close collaboration with Sandry Riffard to turn a shared idea into a truly singular timepiece. Every decision, from the new ergonomic case and reworked movement architecture to the one-of-one enamel dial, was developed as part of the same watch.

“After eight years of designing and making watches, this is one of the most personal and complete pieces we have created.”Raven Reichl · Founder & Lead Designer, ChronoAstra

Your colors.
Sandry's composition.

You choose the emotional palette and share the story behind it. Sandry decides how those colors flow through the dial, approaching each commission as he would a one-off tattoo.

The color atelier

Choose your palette.

Six color directions across two dial materials. Sandry will compose the final arrangement for each collector.

Some colors can only be made well on silver, others on gold. By offering both choices we can expand the possible color combinations to create the most unique special dial for each person.

Both straps are included with every timepiece.

More than 20 hours on the dial alone

Made in fire.
Finished by hand.

A precious-metal foundation

Each dial begins as solid silver or pure 24K gold, prepared and finished by hand before the composition is built.

Lines drawn in precious metal

Every silver or 24K gold partition is shaped, positioned and fixed individually to preserve the flow of Sandry's original artwork.

Color, layer by layer

Enamel is selected for the collector's palette, placed into each cell, fired, cooled and built up through successive layers.

Polished by hand

The finished dial is polished until the metal framework and enamel form a smooth, luminous surface.

No transfer. No printed pattern. No automated color layout. The traces of the human hand are not imperfections. They are the signature that makes your dial yours.
