A 90'S FRENCH MILITARY ICON REBORN

Rooted in French military history, the JB300 defines our foundation. Designed as true instrument watches, function shapes form, and identity is built through real field use.

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.

FXD-style fixed lugs

The Professional pairs a forged carbon case and integrated FXD-style fixed lugs with a Grade 5 titanium inner core and DLC-coated bezel. The combination keeps weight down while providing a strong, corrosion-resistant structure. Fixed lugs eliminate spring bars and provide a secure attachment for a pass-through strap.

The first 200 pieces will also include an exclusive black and red Watches of Espionage × ZA Commando strap.

Super-LumiNova®: Heritage Illuminates the JB300

Since our beginnings, visibility has been one of Jacques Bianchi Marseille's hallmarks. The JB300 transcends darkness to offer unparalleled readability, thanks to the meticulous application of Super-Luminova® on the "Maxi Dial" indices and hands. This luminescent coating ensures perfect clarity, even in abyssal depths, guaranteeing optimal readability.

The clean and functional matte black dial minimizes reflections, while the light emitted by the luminescent elements guides every dive with precision. A true alliance between technical performance and refined aesthetics, making the JB300 an exceptional watch, designed to illuminate your underwater exploration.
