Heritage Chronograph 324.442: Where Sector Dial Tradition Meets Modern Collaboration

The Heritage Chronograph Sector 324.442 stands as a compelling example of how classic design can be meaningfully reinterpreted for a new era. This chronograph, part of the Lebois & Co Heritage collection, takes its inspiration from the sector dial chronographs of the 1940s-a period when clarity, balance, and purpose defined the best in watch design. But the 324.442 is more than a simple homage; it is a product of community-driven creativity, shaped by the shared vision of collectors and enthusiasts worldwide through our CoLAB initiative.

Design Story: The Sector Dial

The sector dial is central to the identity of the Heritage Chronograph 324.442. Unlike more crowded chronograph dials, the sector layout divides the dial into clearly defined zones, each with its own finish and function. The 324.442 features a silver dial with a blue tachymeter scale and a bicompax chronograph layout, omitting the telemeter for a more open, legible appearance. The interplay of sunray and opaline finishes across the dial’s sectors creates subtle contrasts that catch the light and guide the eye, while the blue accents provide a nod to classic instrument design.

This approach to dial design has roots in early 20th-century watchmaking, when legibility and functional clarity were paramount. The sector dial’s precise divisions and minimalist markings reflect the era’s emphasis on scientific instrumentation, making it a favorite among collectors who appreciate both historical context and visual balance.

Origins and Community Collaboration

Ref. 324.442 is not a 1-on-1 reissue of a single vintage model, but rather a contemporary interpretation shaped by archival study and the input of the watch community. Through the CoLAB initiative, participants voted on key elements such as case design, dial layout, and movement selection. The final result is a 39mm stainless steel chronograph with a bevelled bezel and a manually wound column-wheel movement. Details that honor the spirit of mid-century chronographs while meeting modern standards for quality and reliability.

The case combines brushed and polished surfaces, and the domed sapphire crystal adds a vintage profile while protecting the dial. The exhibition caseback reveals the LC-450 movement, developed by La Joux-Perret, with its 60-hour power reserve and fine finishing. This blend of vintage cues and modern execution is a hallmark of the Heritage Chronograph collection.

Every Detail Considered

From the structured sector dial and blue tachymeter scale to the balanced bicompax layout, every aspect of the 324.442 has been carefully considered. The absence of a telemeter scale gives the dial a clean, uncluttered look, while the hour markers and subtle finishing techniques add depth and refinement. The midnight navy leather strap complements the dial and enhances the watch’s understated elegance.

The result is a chronograph that offers both historical resonance and modern practicality-a watch that feels at home in both vintage and contemporary collections.

Sector Dial Legacy

The sector dial’s legacy lies in its ability to combine clarity with character. By reviving this design in the 324.442, Lebois & Co continues a tradition of functional, beautiful chronographs that prioritize legibility and balance. The collaborative design process ensures that the watch reflects not just the brand’s heritage, but the tastes and preferences of today’s watch community.
