Jacques Bianchi Marseille revisits its legendary JB300 military dive watch
After launching the JB200 in 2021 and creating multiple successful variations, Jacques Bianchi Marseille continues its development with a new diving watch that is both technical and stylish: the JB300. A worthy heir to the military model of the early 1990s, the new creation from the Phocaean watchmaking house writes an unprecedented chapter in its history with a piece featuring a committed design and modern lines. A contemporary silhouette that reinvents – with elegance and technicality – the personality of its ancestor.
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 military DNA. This watch reinterprets the stylistic codes of its 1990s predecessor, while incorporating subtle and assertive modernity. Its 42mm 316L stainless steel case, with its generous lugs, ensures robustness and elegance, while the oversized unidirectional bezel remains faithful to the original model, guaranteeing precise handling. The black "Maxi Dial," with a double 24-hour numbering, evokes its past as a military issue watch.
