JB300 Octopus
A watch designed for action
The stonewashed grade 5 titanium gives the watch a vibrant, matte, and deep finish. It reflects less light, shows less wear, and reinforces the tool-like character of the JB300 Poulpro. The work on the case has been taken further. The lines are sharper, the edges more defined, the volumes refined. The JB300 Poulpro is more taut, more precise, and visually more engaging.
Poulpro, an identity forged by usage
Since 2023, the JB200 Poulpro has become a signature. A watch embraced for what it is: legible, serious, expressive, uncompromising. The octopus on the dial has become an instant landmark. No logo. No speech. A strong visual marker, rooted in Jacques Bianchi Marseille's marine DNA. With the JB300 Poulpro, this identity reaches a new technical milestone, without compromise.
Designed in water
The JB300 Poulpro is not a mere stylistic exercise. It is designed based on the concrete constraints of diving, where every detail has a precise function. Its readability is immediate, even in difficult conditions, thanks to generous and clearly defined luminous markers. The unidirectional bezel offers reliable precision, while the overall ergonomics are designed for intuitive use, including in wet environments. At no point does it deviate from its primary purpose: to be a clear, safe, and perfectly controlled diving instrument.
When experience forges precision
Evolving icons without distorting them. Strengthening technique without ever losing the soul. It is in this balance that the JB300 Poulpro is inscribed: a tool above all, born from an alliance of skills and demands.
At JBM, we transpose these constraints into a coherent and homogeneous object, manufactured locally, designed for real use and built to last. A mission watch must know how to disappear on the wrist - until the precise moment when it becomes indispensable.
