JB300 Blue
A navy blue that extends the story
This blue isn't just an aesthetic choice: it evokes the Mediterranean, the sea breeze, and elegantly signifies the Phocaean heritage of Jacques Bianchi Marseille.
The new blue version of the JB300 retains all the technical specifications that have forged its success — 300-meter water resistance, a 42 mm 316L steel case, a unidirectional bezel with wide notching, a Swiss automatic mechanical movement SoProd P024, flat sapphire crystal, and a "Maxi Dial" with a double 12/24 hour scale. The blue dial, unprecedented in the history of the JB300, is treated with a matte finish to preserve perfect legibility in extreme conditions and at great depths.
Style and performance
Resolutely contemporary, the JB300 Blue plays with controlled contrast. The ivory Super-LumiNova® indices, the arrow hand, and the clear minute track stand out boldly against the matte blue dial, which subtly evokes its nautical spirit.
The ensemble is animated by a brushed steel bezel whose "teeth" — faithful to the original model — ensure a remarkably ergonomic grip. True to its original spirit, the watch comes with two interchangeable straps: a navy blue rubber Tropic strap and a black Perlon strap, a nod to its military past. A meticulously designed piece, conceived for both performance and distinction.
A blue edition that makes sense
"The JB300 Blue is much more than a color change," explains Simo Tber, CEO of Jacques Bianchi Marseille. "It's a narrative variation that embodies our deep connection with the sea. This blue is far from decorative: it speaks of depth, discipline, and functional elegance."
For Fabrice Pougez, co-founder of the brand: "It's as much a mission watch as it is a style object. The blue asserts a more universal personality, without denying its purpose as a professional tool."
A field watch, a passion watch
With the JB300 Blue, Jacques Bianchi Marseille demonstrates its ability to keep its heritage alive without ever letting it stagnate. The piece retains its original attributes — robustness, legibility, precision — while embracing a more urban and contemporary aesthetic.
An action watch, certainly, but also a watch for enthusiasts. A watch for the sea. A watch for now. A watch forever.

Super-LumiNova®: Heritage Illuminates the JB300
Since our beginnings, visibility has been one of Jacques Bianchi Marseille's hallmarks.

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