After launching the JB200 in 2021 and creating several highly successful variations, the Jacques Bianchi Marseille brand continues its development with a new dive watch that is both technical and stylish: the JB300. A worthy successor to the military model from the early 1990s, this new creation by the Phocaean watchmaking house writes an unprecedented chapter in its history with a piece featuring a bold design and modern lines. A contemporary silhouette that reimagines – with elegance and technicality – the personality of its predecessor.

After more than two years of intensive development, Jacques Bianchi Marseille unveils the JB300, a true tribute to the brand’s history and its military heritage. A watch that retains the stylistic codes of its 1990s predecessor, while introducing a subtle yet assertive modernity. Its 42mm 316L steel case, with generous lugs, ensures both robustness and elegance, while the oversized unidirectional bezel remains faithful to the original model, guaranteeing precise handling. The black “Maxi Dial” dial, with a dual 24-hour numbering, recalls its origins as a military-issued timepiece.
