Description:
The Ba111od Chapter Delta 7 Ella Black Diamond 40mm blends innovative haute horlogerie with contemporary luxury. This model combines BA111OD’s revolutionary CHPTR_Δ architecture with refined elegance, highlighted by its sophisticated anthracite tone and bezel set with natural black diamonds.

Instead of a traditional rotating hand, the movement “rolls” a satellite hour wheel around a fixed central wheel. This interaction generates a mathematical cycloid. In this version, a deltoid hypocycloid (ratio 1/3) is used, causing the tip of the hour hand to trace a perfect triangle.

Developed with renowned watchmaker Olivier Mory, this asymmetrical time display represents a world premiere, offering a unique visual and mechanical experience.

The watch houses a Swiss automatic movement based on the Soprod M100, enhanced by the BA111OD manufacture module 09310. Power reserve reaches 42 hours.

The 40 mm 316L stainless steel case with anthracite PVD coating provides balanced proportions and elegant presence. The bezel set with 80 natural black diamonds adds discreet luxury to the Ella Black Diamond edition.

The multi-level satin matte dial with laser engraving reinforces its architectural character, while the polished steel faceted triangle with white dot aligns with the geometric triangular time concept.

Protected by a domed sapphire crystal with anti-reflective treatment, the watch ensures clarity and durability.

Available with rubber or leather strap with deployant clasp, both featuring the Easy-Clip system, this model merges Swiss innovation with refined sophistication.

The Chapter Delta 7 Ella Black Diamond redefines modern luxury watchmaking, where engineering and jewelry craftsmanship meet in perfect harmony.
