JB300 Black
Jacques Bianchi Marseille revisits its legendary military dive watch
After launching the JB200 in 2021 and declining the model into several successful series, Jacques Bianchi Marseille continued its development with a diving watch that is both technical and stylish: the JB300. A worthy heir to the military model of the early 1990s, the JB300 thus wrote a new chapter in the history of the Marseilles watchmaking house—a piece with an assertive design, modern lines, which elegantly and technically reinvents the personality of its predecessor.
JB300, the ultimate dive watch from Jacques Bianchi Marseille
After more than two years of intensive development, Jacques Bianchi Marseille unveils the JB300, a true homage to the brand's history and its military DNA. This watch reinterprets the stylistic codes of its 1990s ancestor, while adding a subtle yet assertive modernity. Its 42mm 316L steel case, with its generous lugs, ensures robustness and elegance, while the oversized unidirectional bezel remains faithful to the original model, guaranteeing a precise grip. The black "Maxi Dial", with its double 24-hour numbering, evokes its past as a military issue watch.
