- The present watch showcases the unlikely collaboration between Louis Erard, a brand celebrating its 90th anniversary today and known for its classical watches, and Vianney Halter, a legendary independent watchmaker. Halter first captivated the world in 1998 with his mind-boggling perpetual calendar, the Antiqua—a steampunk creation reminiscent of the imaginative works of Jules Verne and H.G. Wells—that transformed our perception of fine watchmaking.

- As an independent artisan, Halter produces only a handful of watches each year, with pieces typically spoken for before completion. The time, energy, skill, and craftsmanship invested in each piece justify their high price tags.

- Beginning with the Antiqua and followed by the Classic and Trio, Halter along with his then design partner Barnes, developed a personal and instantly recognizable design language, which he has adeptly applied to the Louis Erard Regulator.

- The present model, limited to 178 pieces, was launched in 2020 and sold out within hours, highlighting the demand among collectors for this type of collaboration.

- The dial features a two-level architecture with a mix of polished and sandblasted surface finishes. The typography of the numerals and the hands are characteristic of Halter's style, found in his own creations. Additionally, the notches on the crown pay homage to the rivet-studded crowns of the Antiqua, Classic and Trio.

- This modern take on the classic regulator design, the Louis Erard X Vianney Halter, offers an extraordinary opportunity to own a piece that exemplifies his remarkable creative genius.
