In the world of watchmaking, tradition and innovation often walk a fine line. Few brands understand this dynamic better than Louis Erard. The newly introduced Le Régulateur Gravé Bleu is a striking example of this balance—where meticulous craftsmanship meets contemporary vision. A watch that not only tells time but also tells a story, this latest addition to the brand’s Noirmont Métiers d’Art collection reinterprets a historical aesthetic with a modern edge.

Reviving a Legacy: The Evolution of the Sector Dial

Horology has always been a canvas for artistic and technical refinement. The sector dial, which rose to prominence in the 1930s, was initially designed for precision reading. It broke away from traditional layouts, offering a structured, scientific approach to timekeeping. Louis Erard, known for championing artisanal crafts, has reimagined this enduring format by incorporating fine engraving techniques—a tribute to both watchmaking heritage and the pursuit of aesthetic depth.


The Le Régulateur Gravé Bleu takes this legacy forward, presenting a contemporary interpretation that respects the past while embracing the future. By joining the permanent collection, this watch cements itself as a defining piece in Louis Erard’s commitment to accessible haute horlogerie.

A Thoughtful Approach to Case Design and Materials

Designed with both artistry and comfort in mind, the Le Régulateur Gravé Bleu pairs easily with any setting, from work to relaxation

Precision and proportion form the foundation of this watch’s design. Encased in polished stainless steel, the Le Régulateur Gravé Bleu measures 39 mm—a dimension that ensures a harmonious fit for various wrist sizes while maintaining a refined presence. The interplay of polished surfaces and the signature fir tree crown creates an understated elegance, reinforcing Louis Erard’s ethos of “Less is More, More is Less.”


A domed sapphire crystal with anti-reflective treatment enhances legibility, while a transparent caseback provides a glimpse into the movement within. Water resistance of up to 50 metres ensures versatility, allowing the watch to transition seamlessly between formal and casual settings.

The Dial: A Study in Engraved Precision

The dial of the Le Régulateur Gravé Bleu is where the watchmaker's artistry truly shines. A deep blue, fine-grained surface serves as the backdrop for intricate rhodium-plated engravings. The careful application of engraving techniques adds depth, giving the dial a three-dimensional quality that changes with the light.


The régulateur layout—a defining trait of Louis Erard’s identity—remains intact. The separation of hours, minutes, and seconds provides both visual intrigue and functional clarity. Rhodium-plated fir tree hands glide across the dial, reinforcing the brand’s dedication to refined detailing.

The Movement: Mechanical Mastery with a Contemporary Edge

At the heart of the Le Régulateur Gravé Bleu is the Sellita SW266-1 calibre. This automatic regulator movement operates at 28,800 vibrations per hour (4 Hz) and boasts a 38-hour power reserve. Beyond its technical reliability, the movement is elevated by thoughtful finishing, including a special openworked oscillating weight adorned with Louis Erard’s emblem in black lacquer.


The selection of this movement underscores the brand’s philosophy: fine watchmaking should be both mechanically compelling and accessible to a broader audience. The Le Régulateur Gravé Bleu offers a mechanical experience that is as engaging as it is precise.

Bracelet and Wearability: Comfort Meets Craft

Louis Erard understands that a watch is more than just its dial or movement—it is a daily companion. The Le Régulateur Gravé Bleu comes fitted with a light grey grained calf leather strap, offering both visual contrast and tactile refinement. The strap’s black grained calf leather lining ensures a comfortable wear, while the polished stainless steel pin buckle provides security with a classic touch. Quick-release spring bars enable effortless strap changes, allowing wearers to adapt the watch to different occasions or moods with ease.

Final Thoughts: A Watch That Speaks to Craft and Character

With the Le Régulateur Gravé Bleu, Louis Erard continues to refine its distinctive vision of horology—one that pays homage to a time-honoured tradition while embracing bold creativity. This creation is not simply an object of mechanical precision; it is an expression of artistry, designed for those who appreciate the depth of fine watchmaking.


By integrating traditional engraving techniques with a contemporary aesthetic, Louis Erard has once again demonstrated its ability to challenge convention while staying true to its independent spirit. The Le Régulateur Gravé Bleu is more than a watch—it is a statement of craftsmanship, heritage, and modernity, all in one.
