Lebois & Co Heritage Sector Chronograph Aventurine

Indie brand Lebois & Co expands its Heritage collection with the Heritage Sector Chronograph Aventurine, a new version of the brand’s vintage-inspired chronograph distinguished by a textured aventurine dial and a revised sector-style layout. The watch also debuts a better naming structure within the brand’s catalogue, with “Heritage Sector” becoming the designation for Lebois & Co’s sector-dial designs alongside other sub-families such as Heritage Atelier and Heritage Script.

The series’ stainless steel case remains, measuring 39mm in diameter, 13.9mm in thickness, and 47.35mm lug-to-lug. The case features a mix of brushed and polished surfaces, elongated chronograph pushers and a knurled crown, topped by a double-domed sapphire crystal. Water resistance is rated at 50m.

The dial is where this new edition is different. Aventurine glass, with its microscopic metallic inclusions, gives the watch a constantly shifting visual depth. Lebois & Co contrived a multi-layer dial construction to accommodate the recessed counters. The dial sits on a brass base and is built from two aventurine layers (0.40mm and 0.35mm thick), allowing the sub-dials to be hollowed out.

The layout adopts a sector dial design, with concentric tachymeter and minutes/seconds tracks and clear numerals. The chronograph minutes are at 3 o’clock, and the running seconds subdial is at 9. The central chronograph hand looks sharp as a needle, while the hour and minute hands, numerals and sector markings are treated with BGW9 Super-LumiNova.

The watch is powered by the LC-450, the brand´s name for the manual-winding La Joux-Perret column-wheel chronograph movement. Operating at 28,800 vibrations/hour, the calibre delivers a 60-hour power reserve and features traditional chronograph construction with a column wheel. The movement and its finishing, including perlage and Geneva stripes, can be seen through the sapphire caseback.

The watch is worn on a leather strap and priced at EUR 3,850 including VAT. Offered as an inaugural batch, the first production run opens for orders on 10 March 2026, with deliveries expected from July 2026. For more information, please visit LeboisandCo.com.
