JB300 POULPRO
JACQUES BIANCHI MARSEILLE JB300 POULPRO TITANIUM GRADE 5
Dated 2025, the JB300 Poulpro: a technical container machined from Grade 5 titanium, conceived for water, real-world use, and long-term durability.
The case is treated through successive micro-bead blasting (“stonewashed”), a deliberately time-intensive process refined through multiple iterations to achieve a precise balance: a matte, non-uniform surface with low reflectivity, improved resistance to micro-impacts, and a deliberately embraced patina.
Here, titanium does not seek neutrality.
It asserts a tool-driven character. Raw, alive, and maritime in nature.
A WATCH DESIGNED FOR ACTION
The stonewashed Grade 5 titanium gives the watch a living, matte, and deeply textured presence. It reflects less light, shows wear more discreetly, and reinforces the JB300 Poulpro’s tool-watch character.
The work on the case has been taken further. The lines are sharper, the edges more defined, and the volumes refined. The JB300 Poulpro is tauter, more precise, and visually more committed.
POULPRO, AN IDENTITY FORGED BY USE
Since 2023, the JB200 Poulpro has established itself as a signature. A watch embraced for what it truly is: legible, serious, expressive, and uncompromising.
The octopus on the dial has become an immediate point of reference. No logo. No rhetoric. A strong visual marker, deeply rooted in the maritime DNA of Jacques Bianchi Marseille. With the JB300 Poulpro, this identity reaches a new technical threshold—without betraying its origins.
Conceived in water
The JB300 Poulpro is not an exercise in style. It is designed around the concrete constraints of diving, where every detail serves a precise function.
Legibility is immediate, even in demanding conditions, thanks to generous, clearly defined luminous markers. The unidirectional bezel delivers reliable precision, while the overall ergonomics are conceived for intuitive use, including in wet environments.
At no point does it stray from its primary purpose: to be a diving instrument that is clear, secure, and perfectly controlled.

super-luminova®
At Jacques Bianchi Marseille, visibility remains a fundamental promise.
The JB300 Poulpro Titanium, with its Maxi Dial, combines applied indices and hands in egg-shell Super-LumiNova® with green emission, in perfect coherence with the bezel’s luminescent marker.
LEADER IN THE FRENCH DIVE WATCH INDUSTRY
A leader in the French watchmaking industry, Jacques Bianchi Marseille continues to push the boundaries of innovation with the JB300. An heir to the military diving watches of the 1990s, the JB300 Profonde flawlessly combines rugged spirit with the modernity of contemporary lines. True to its heritage, it preserves the soul of professional diving watches with its oversized bezel and ultra-readable dial. The JB300 Profonde honours its military legacy, appealing to both diving enthusiasts and watch collectors alike.

WHEN EXPERIENCE FORGES PRECISION
Evolving icons without distorting them. Strengthening the technical dimension without ever losing the soul.
It is within this balance that the JB300 Poulpro takes its place: first and foremost a tool, born of an alliance of expertise and exacting standards.
At JBM, these constraints are translated into a coherent, homogeneous object, locally assembled, designed for real-world use and built to endure. A mission watch must know how to disappear on the wrist—until the precise moment it becomes indispensable.
A house born to serve.
Jacques Bianchi Marseille embodies a culture of function and issued equipment: operational simplicity, proven materials, legible architecture, and a sense of service. The JB300 Poulpro extends this approach, giving absolute priority to the reading of essential time, tactile reference points, and the overall robustness of the watch.
The Marseille-based watchmaking house maintains a living connection with special units. In continuity with its military-issue roots and its ongoing exchanges in the field, JBM sustains a constant dialogue with professionals of engagement—divers and embarked personnel alike.
The JB300 Poulpro belongs to this continuum: a loyal tool, designed to be worn, understood, and repaired.
A tool first and foremost.
Stonewashed Grade 5 titanium case, with controlled proportions of 41.5 mm in diameter and 13 mm in thickness, featuring a 20 mm lug width.
A knurled unidirectional bezel is fitted with a luminescent marker at 12 o’clock for immediate orientation. Sapphire crystal, screw-down protected crown, and water resistance guaranteed to 300 metres. The watch is powered by the Swiss automatic Soprod P024 movement, valued for its reliability and ease of maintenance.
It is fitted with a JBM technical textile strap and produced in a limited edition, individually numbered XXX/300.
