A Journey into Enamel

Behind every enamel dial lies a process shaped by patience, fire, and unforgiving precision. From raw copper to luminous Grand Feu, this photo series documents each stage of the creation — revealing what it truly takes to transform elemental materials into a timeless watch dial. Each step is handcrafted in Switzerland by master artisans. No shortcuts. No second chances. Only the flawless remain.

The base takes shape

A thin copper disc is cut and formed to match the dial’s exact curvature. This blank will carry not only layers of enamel, but the weight of precision.

Anchored by hand

Two small copper feet are manually pinned and soldered in place. They allow the finished dial to mount perfectly to the movement — misalignment is not an option.

Purified by hand

The raw enamel powder — made from crushed mineral glass — is ground and washed in water to remove impurities. This slow, tactile process ensures a clean, even surface after firing.

The first coat

A thin layer of enamel is applied to both sides of the dial. This isn’t aesthetic — it balances internal tension during firing. Enamelling on both sides is essential for stability.

Fired at 800°C

The dial enters the kiln. At this stage, it's just enamel powder on copper — but under intense heat, glass begins to fuse, and the surface gains depth. Most dials don't survive the first few firings.

Printed, layer by layer

Each color is pad-printed one by one, aligned with extreme precision. On a curved enamel surface, any shift — even a fraction — means the dial must be scrapped.

Three parts, one dial

This dial isn’t a single piece. The subdials are produced separately, then set into place and filed flush. The result: perfect integration, made invisible by skill.

Only the flawless remain

After the final firing, each dial is checked under magnification and projection. Print tension, shape, and enamel consistency must be perfect — or it's rejected.

The final surface

The result: a luminous, tension-free dial, deep in tone and rich in character. From copper to color, every step leaves its mark — even the invisible ones.
