Louis Erard reimagined the iconic sector dial, a hallmark of 1930s watchmaking, while incorporating its signature Régulateur design with its distinctive vertical display of time indicators. This technical and aesthetic precision highlights the key elements: time segmentation, optimized readability, concentric circles, and a railway track motif. Engraved markers, treated with a brilliant galvanic finish, create a subtle interplay of relief against the finely grained blue dial, all housed in a polished 39mm steel case. A minimalist design that ensures a clear and elegant reading of the time. Le Régulateur Gravé Bleu joins Louis Erard's Noirmont Métiers d'Art collection, embodying the very soul of the brand, which has been rooted in the Swiss Jura region since 1992.
