Le Régulateur Gravé Bleu, Louis Erard’s Tribute to the Sector Dial

Louis Erard presents its latest release, the "Le Régulateur Gravure Bleu," a watch that, as the company describes, embodies the concept of the "Napkin Strategy." This well-known business term refers to a simple, concise idea, often improvised, symbolizing its ability to be quickly sketched on a napkin.

Louis Erard introduces Le Régulateur Gravé as a permanent addition to its Noirmont Métiers d'Art line, reinterpreting the sector dial with intricate traditional engraving. By presenting this non-limited model, Louis Erard further solidifies its distinct identity while making its rare design more accessible to a wider range of enthusiasts.

Balance spring or hairspring

Balance spring or hairspring

The balance spring, often referred to as the hairspring, is an essential part of a mechanical watch movement that contributes to its timekeeping precision. This delicate, coiled metal spring is connected to the balance wheel, which oscillates within the watch's movement.

The hairspring, or balance spring, is usually made of metal alloys like Nivarox, which consists of iron, nickel, chromium, titanium, and other elements. Nivarox is popular due to its resistance to temperature variations, magnetic fields, and corrosion. Some watch manufacturers have also developed silicon hairsprings for their high-end models, offering improved resistance to temperature changes, magnetic fields, and wear.

The main role of the balance spring is to supply a counterbalancing force that keeps the balance wheel oscillating at a steady pace. The balance wheel's back-and-forth motion causes the balance spring to expand and contract, enabling the wheel to sustain a stable oscillation. The accuracy of the watch's timekeeping depends on the balance spring's precise and consistent performance.
