The Craftsmanship of Guilloché
Guilloché is a horological technique that creates patterns on watch surfaces through alternating peaks and troughs. The process involves specialized machinery that engraves linear or geometric designs into metal, building depth through controlled elevations and depressions. This manual and mechanical combination preserves traditional methodology while producing surfaces that catch light distinctly.
Cheng Yucai: Master Guillocheur
Cheng Yucai is the guillocheur of Xinmi, working with ATELIER WEN to produce guilloché dials and surfaces. He combines traditional hand techniques with period machinery, controlling the depth, angle, and pattern rhythm of each design. His work requires consistent pressure, precise tool control, and the ability to visualize how light will interact with the finished surface.
The Process
Guilloché employs specialized machinery—often featuring rotating cutting heads and hand-guided or mechanically indexed positioning systems—to engrave designs onto watch surfaces. Cheng works with traditional rose engines and modern variants, selecting tools and speeds appropriate to the metal and desired pattern. A swirling motif demands different approach speeds and tool geometry than geometric patterns; each design class presents its own technical requirements.
The Impact on Luxury Watches
Guilloché offers functional durability alongside visual distinction. The textured surface created by the pattern resists fingerprints and minor scratches more effectively than polished dials, as light scattering across the ridges obscures shallow marks. Collectors value these dials for both properties: they photograph distinctly under varying light, and they age differently than smooth surfaces, developing character over years of wear.
ATELIER WEN: A Journey of Time and Craft
The collaboration between Cheng Yucai and ATELIER WEN reflects the commercial viability of dial finishing as a differentiator in competitive watchmaking. Guilloché-equipped timepieces command recognition among collectors who distinguish between mass-produced and hand-finished examples. For those exploring luxury horology, ATELIER WEN collections demonstrate how surface finishing informs both mechanical watchmaking and design philosophy.
Each guilloché dial represents accumulated control over equipment and material response. The practice persists because it remains difficult to replicate by other methods, preserving value for brands that commit to the technique and the artisans who master it.
Frequently Asked Questions
What is guilloché and how is it used in luxury watchmaking?
Guilloché is a horological finishing technique that creates patterns on watch surfaces through alternating peaks and troughs. The process combines specialized machinery with hand-guided positioning, allowing craftspeople like Cheng Yucai to produce designs that transform simple dials into visually and tactilely complex surfaces.
Who is Cheng Yucai and what makes him significant to ATELIER WEN?
Cheng Yucai is the guillocheur of Xinmi who produces guilloché surfaces for ATELIER WEN’s collections. He controls the technical variables—tool selection, feed rate, pattern sequencing—that determine the final appearance and quality of each finished dial.
Does guilloché offer any practical benefits beyond aesthetics for luxury watches?
Guilloché improves dial durability by creating texture that resists visible fingerprints and shallow scratches. The light-scattering properties of the ridged surface obscure wear marks more effectively than polished dials, and the finished surface develops character over time differently than smooth finishes.
