Jacques Bianchi Marseille has introduced the JB300 Poulpro, expanding its Poulpro line with a more technically focused dive watch built on a titanium platform. Rated to 300 meters and produced as a limited run of 300 pieces, the JB300 Poulpro is positioned as a step up from the earlier JB200, with an emphasis on durability, legibility, and professional dive specifications.
While the Poulpro name is already associated with bold graphics and an unconventional visual identity, the JB300 shifts the balance toward function. The goal here appears to be refinement rather than reinvention, keeping the recognizable design cues intact while pushing the watch into a more serious tool watch category.
The JB300 Poulpro continues a thread that began with the JB200 Poulpro, a model that drew attention for its strong dial graphics and prominent octopus motif. That visual identity has not been abandoned. Instead, I feel as if it’s been adjusted and scaled to better support readability and overall coherence. The octopus remains at six o’clock, but in a reduced form that plays a supporting role rather than dominating the dial. Good call.
This shift is most evident in the overall design language. Where the JB200 leaned heavily into playful character, the JB300 presents a more restrained, purpose-driven aesthetic. Oversized luminous markers, a darker matte case finish, and a simplified visual hierarchy suggest a watch designed with real-world diving constraints in mind, without stripping away the elements that make a Poulpro immediately recognizable.
There is also a clear historical reference at work. The JB300 designation traces back to Jacques Bianchi’s professional and military dive watches from the 1990s, and the Poulpro variant leans into that lineage. On paper, it aligns more closely with that era’s utilitarian dive instruments than with vintage-inspired reinterpretations.
The Grade 5 titanium case measures 41.5mm in diameter, 13mm thick, with a 20mm lug width. The surface is finished using successive micro bead blasting to produce a matte, stonewashed appearance with an intentionally uneven texture. Rather than highlighting titanium’s ability to take on refined finishing, the approach here prioritizes low reflectivity and resilience. Water resistance is rated to 300 meters, an increase over the JB200 Poulpro.
Powering the watch is the Swiss automatic Soprod P024, picked for its reliability and straightforward service profile. It is a practical choice that aligns with the utilitarian direction of the watch and avoids unnecessary complication.
The dial is a textured black Maxi Dial protected by a sapphire crystal. Applied indices and hands are filled with Super Luminova in an eggshell tone that emits a green glow, matched by the luminous pip on the bezel. The watch is delivered on a black Tropic-style rubber strap, with an additional gray JBM technical textile strap included.
As a release, the JB300 Poulpro presents a cohesive package. To me, the specifications, materials, and finishing choices all point in the same direction, reinforcing the watch’s tool-focused intent. The use of Grade 5 titanium in this deliberately roughened form stands out, particularly in a market where the material is often paired with decorative finishing (and pricier watches). Here, surface wear is less a concern and more an expected part of ownership.
The JB300 Poulpro is a numbered limited edition of 300 pieces, priced at €1,079 (excluding VAT). Preorders are open through the Jacques Bianchi website, with deliveries expected in February 2026.
