Swiss Precision at Its Finest
Chapter 7 marks a new milestone for BA111OD as its first chronometer-certified timepiece, officially tested by the Observatoire chronométrique de Genève (TIMELAB). Each movement undergoes rigorous individual testing, ensuring exceptional precision of -4/+6 seconds per day, far surpassing standard mechanical watches. This level of accuracy is a testament to BA111OD’s dedication to Swiss watchmaking excellence. Each watch will come with its chronometry performance report, an individual certificate attesting to its accuracy.
Refined Design with a Bold Edge
A perfect balance between tradition and innovation, Chapter 7 was designed by Liliane Murenzi, BA111OD’s in-house Senior Designer, to seamlessly blend technical mastery with aesthetic refinement. The sleek 40mm stainless steel case features a distinctive faceted bezel, playing with light through a mix of satin and polished finishes. The sunray dial with cascading guilloché pattern adds depth and character, making it more than just a timepiece—it’s a statement of modern elegance.
Built for Every Moment
Chapter 7 is designed to adapt to every lifestyle. Whether in the city, at work, or exploring the outdoors, its 100m water resistance and robust construction make it a reliable companion. Available with a rubber strap for a sporty look or a stainless steel bracelet for timeless sophistication, this watch seamlessly transitions with you, wherever you go.
Innovation Rooted in Swiss Heritage
BA111OD continues to push the boundaries of accessibility and innovation while remaining true to its roots in Neuchâtel, the heart of Swiss watchmaking. Each Chapter 7 timepiece is expertly assembled by our father-and-daughter watchmaking duo, Regi & Rebecca, in our Neuchâtel workshop, ensuring exceptional craftsmanship at every step. A perfect fusion of cutting-edge technology and traditional savoir-faire, Chapter 7 is designed not just to be worn, but to be experienced.
