The Excellence Guilloché Main II: Hand-Engraved Dial
LOUIS ERARD’s Excellence Guilloché Main II centers on a hand-engraved dial executed with the guilloché technique—a pattern-cutting process applied directly to the metal surface. The dial’s second-hand guilloché creates visible depth and texture variation across the face, the result of manual craftsmanship that differs slightly from piece to piece.
Guilloché Execution and Surface Treatment
Guilloché involves cutting fine, parallel or radiating lines into metal using specialized engraving tools, typically mounted on geometric guides. On the Excellence Guilloché Main II, this creates a secondary dial surface with light-catching properties—the pattern shifts appearance depending on viewing angle and light condition. The technique demands trained hands and calibrated equipment; deviation in line spacing or depth becomes immediately visible under magnification.
Design Integration
LOUIS ERARD pairs the guilloché dial with a streamlined case and refined hour markers. The watch functions as both a timekeeping instrument and a study in surface finish variation. The dial’s optical properties—how light reflects through the engraved pattern—form the primary visual interest rather than applied graphics or enamel work.
Technical Specifications and Construction
The Excellence Guilloché Main II is built on a foundation of case work and movement assembly consistent with LOUIS ERARD’s manufacturing standards. The hand-engraved dial distinguishes each watch, as manual cutting introduces natural variation in line precision and light-catch properties. Combined with the case geometry and marker placement, the dial defines the watch’s character.

Frequently Asked Questions
What is the guilloché technique used in the Louis Erard Excellence Guilloché Main II?
Guilloché involves cutting fine, parallel or radiating lines into the dial’s metal surface using specialized engraving tools. The Excellence Guilloché Main II features a hand-engraved dial where this technique creates depth and light-catching properties that vary depending on viewing angle. Each dial is distinct due to the manual process.
How does the Excellence Guilloché Main II balance tradition and innovation?
The Excellence Guilloché Main II relies on traditional hand-engraving methods applied to a contemporaneously refined case and marker set. LOUIS ERARD maintains the classical guilloché process without automation while integrating it into modern watch proportions and finishing standards.
What makes the dial design of the Excellence Guilloché Main II distinctive?
The dial’s guilloché pattern creates optical effects through its engraved line structure. Light reflects differently across the surface depending on angle and ambient conditions, making the dial appear to shift subtly. Combined with the case proportions and hour markers, this optical behavior distinguishes the watch from printed or applied dial finishes.
