The Art of Mastering Gravity

A bold statement of mechanical poetry and Swiss precision. Designed for aesthetes and collectors, this chronometer-certified masterpiece elevates timekeeping into an art form.

Encased in a subtly concave 41mm polished 904L stainless steel case with welded lugs, the timepiece showcases a cosmic blue sunray dial with a mesmerizing flying tourbillon at 7 o’clock, a hammered and polished moon phase at 1 o’clock, and a small seconds subdial at 10 o’clock. The dome-shaped box sapphire crystal reveals a meticulously hand-wound movement offering a 120-hour (5 day) power reserve.

Developed in collaboration with acclaimed watchmaker Olivier Mory in La Chaux-de-Fonds, the flying tourbillon appears to defy gravity — its cage suspended in motion, compensating for gravitational effects to optimize precision. Certified by Timelab – Observatoire Chronométrique de Genève, the movement is a testament to exceptional accuracy and savoir-faire.

Rooted in the centuries-old heritage of the Baillod family, this timepiece captures the spirit of Neuchâtel — where tradition meets disruption.

Swiss-made, Neuchâtelois, and bold

THE ART OF MASTERING GRAVITY

With its flying tourbillon appearing to float in mid-air, the Chapter 4 Infinity is a celebration of mechanical poetry. Freed from its upper bridge, the tourbillon rotates gracefully at 7 o’clock, compensating for the effects of gravity and enhancing chronometric precision. Its hypnotic motion reminds us that watchmaking, at its highest level, is not just engineering — it’s art.

SWISS EXCELLENCE, CERTIFIED

At the heart of this hand-wound timepiece beats a movement developed with renowned watchmaker Olivier Mory in La Chaux-de-Fonds. With a 120-hour (5 day) power reserve and chronometer certification by Timelab – Observatoire Chronométrique de Genève, it embodies uncompromising performance and accuracy. Haute horlogerie, backed by scientific rigor.

A COSMIC DESIGN

Housed in a subtly concave 41mm polished 904L steel case with welded lugs, the watch features a stunning cosmic blue dial with sunray finishing. The harmonious layout includes a hammered moon phase at 1 o’clock, a small seconds subdial at 10, and a domed box sapphire crystal that reveals every detail of the movement beneath. Bold and elegant, it commands attention without ever shouting.

A Legacy Reinvented

Rooted in Neuchâtel’s centuries-old watchmaking heritage, BA111OD continues to disrupt with innovation, daring, and accessibility. The Chapter 4 Infinity Flying Tourbillon is not just a tribute to tradition — it’s a bold evolution of it. Designed for those who seek both meaning and mastery in their timepiece.
