Design and Construction

With its elegantly symmetrical layout and meticulous details, the Louis Erard Excellence Regulator reference 54230AA01.BDC02 achieves remarkable poise and visual appeal. This Swiss-made timepiece brings thoughtful design touches together in a cohesive modern aesthetic.

A regulator-style dial places the hour and minute hands on separate subdials, allowing for precise time readings. The clean two-subdial layout creates harmony, with blued steel hands providing subtle contrast against the grey dial. Polished applied indexes catch the light elegantly.

The 40mm stainless steel case adds durability and versatility to the Excellence Regulator's sophisticated aesthetic. Subtle alternating finishes on the case add depth and nuance. The exhibition case back reveals Louis Erard's self-winding LE231 movement through a sapphire window.

The Regulator exudes meticulous quality inside and out from the embossed alligator leather strap to the signed crown. With its refined symmetry and expert details, Louis Erard's Excellence Regulator balances aesthetics and precise timekeeping.

Exploring the Features

In addition to its aesthetic appeal, the Louis Erard Excellence Regulator reference 54230AA01.BDC02 boasts an array of thoughtful features that enhance functionality. This sophisticated timepiece demonstrates the brand's focus on precision and quality.

At the heart of the Regulator is Louis Erard's self-winding LE231 movement. This 26-jewel calibre beats at 28,800 vibrations per hour with a 42-hour power reserve. The regulator-style dial highlights the movement's accuracy.

The hour and minute hands occupy separate subdials, allowing for precise time reading. Blued steel hands provide legibility against the grey opaline dial, while applied polished indexes add subtle sparkle. A small second subdial sits at 6 o'clock.

Additional features emphasize attention to detail. The box sapphire crystal on the 40mm stainless steel case is anti-reflective on both sides for easy readability. Super-LumiNova lume provides visibility in low light conditions. An embossed alligator strap fastens securely with a signed folding clasp.

With its meticulous details, the Excellence Regulator exemplifies Louis Erard's focus on functionality and aesthetics. From its regulator dial to LE231 movement, this timepiece achieves a masterful balance of precision and elegance.
