BA111OD has introduced two new variations of its Chapter 4 Flying Tourbillon collection, the Onyx and the Infinity, each offering a distinct aesthetic while sharing the same core mechanical architecture. These models aim to make complex watchmaking complications more accessible, featuring a 41mm stainless steel case and a hand-wound movement with a five-day power reserve.
- 41mm stainless steel case
- Hand-wound movement
- Five-day power reserve
- 50 meters water resistance
The Onyx model features a polished natural black onyx dial, allowing the flying tourbillon to be the primary focus.
The Infinity model presents a cosmic blue sunray dial with an off-centre layout, a hammered moon phase at 1 o'clock, and a small seconds display at 10 o'clock, balancing the tourbillon at 7 o'clock.
Both watches have a 41mm stainless steel case with a concave profile and a recessed bezel, designed for comfort.
A distinctive design element is the 4 o'clock crown, engraved with the brand's emblem, which enhances wearability.
The movement, BA.02, is based on the BCP Tourbillon and features a variable-inertia balance wheel, ticking at 21,600 vibrations per hour.
The Infinity model's movement is chronometer-certified by Timelab in Geneva.
Both versions are equipped with magnetic (2000 Gauss) and shock (5000G) resistance.
Straps are interchangeable via an easy-clip system; the Onyx model comes with a black calf leather strap, and the Infinity with a dark blue leather strap.
