BA111OD’s Chapter 4 Onyx Flying Tourbillon is a study in precision and restraint. At its centre, the flying tourbillon appears to float above a polished black onyx dial, free from any upper bridge. The dial’s depth draws the eye inward, with light absorbed rather than reflected, placing full attention on the movement. It’s a natural progression from the outgoing Chapter 4.7, trimmed back to its essential elements without losing its technical edge.
The 41mm case, crafted from polished 904L stainless steel, features a concave profile and recessed bezel, giving the watch a distinct visual balance. Inside, a hand-wound calibre developed with Olivier Mory keeps the mechanism exposed and deliberately framed. A subtle logo sits tone-on-tone at twelve, integrated rather than imposed, in keeping with the watch’s quiet presence.
Rooted in Neuchâtel, BA111OD blends traditional Swiss craftsmanship with a clear, contemporary language. The Chapter 4 Onyx Flying Tourbillon doesn’t chase attention, it rewards it. Stripped of excess but rich in intent, it’s a reflection of modern watchmaking grounded in substance.
