The JB300 Poulpro arrives as Jacques Bianchi Marseille’s latest take on a serious dive watch. It pairs some of the frivolous style of the earlier JB200 Poulpro with a more technical, titanium-based platform. This isn’t about flash; it’s about refining a recognized design language into something even more purposeful.

In dive watches, there’s a fine line between stylistic gestures and genuine function. The Jacques Bianchi JB300 Poulpro matters because it leans clearly toward the latter. The aim was to build a serious tool for demanding conditions while keeping it rooted in the quirky visual identity that made the original Poulpro stand out. Let’s have a closer look!

JB300 Poulpro in context

The JB300 Poulpro continues a thread that began with the JB200 Poulpro, a model that quickly gained attention for its bold graphics and octopus motif. With the JB300, Jacques Bianchi hasn’t abandoned that visual identity; instead, it pushes the concept into a new, more technical frontier.

Where the JB200 often felt like a quirky modern reinterpretation of a vintage dive watch, the JB300 Poulpro aims at something more hardcore. Its design is clearly informed by real-world diving constraints, from a matte “stonewashed” titanium case to oversized luminous markers designed to remain clear at depth. There’s less flair and more functional intent here, without losing the character that matters to enthusiasts. The now-smaller octopus on the lower half of the dial also interferes with legibility much less than it did on the JB200 Poulpro.

This model also draws from a deeper historical lineage for the brand. Jacques Bianchi Marseille’s JB300 line itself traces its roots to military and professional dive watches from the 1990s, and the Poulpro iteration leans into that heritage. It looks and feels like a 1990s military dive watch to me.

Specifications

The JB300 Poulpro features a Grade 5 titanium case with a 41.5mm diameter, a 13mm thickness, and a 20mm lug spacing. The “stonewashed” titanium is finished with successive micro-bead blasting to achieve a matte surface that resists reflections and appears uneven and flaky. I mean that in a good way, even if it might not sound like it. The watch is water resistant to 300 meters, up from 200 for the JB200 Poulpro.

Inside ticks a Swiss automatic Soprod P024 movement, chosen for its reliability and straightforward maintenance profile. I would say this is a sensible choice for a no-nonsense dive watch.

Underneath the sapphire crystal lies a “Maxi Dial” with a textured black surface with the signature octopus motif at 6 o’clock. Applied indexes and hands are filled with Super-LumiNova in an eggshell tone with a green glow, matching the bezel’s luminous pip. The watch is supplied on a black Tropic-style rubber strap, and a gray JBM technical textile strap is also included.

Initial impressions of the Jacques Bianchi JB300 Poulpro

Some watches do just “as it says on the tin.” I have said this about Jacques Bianchi models before, and it applies to the JB300 Poulpro. This feels like an honest and straightforward release that will surely land well with Jacques Bianchi fans. The specs are on point, the price is very reasonable, and the design is Jacques Bianchi through and through. What’s not to love?

I particularly appreciate the different approach to using Grade 5 titanium. Manufacturers often opt for Grade 5 to apply fancier finishing, but Jacques Bianchi goes the opposite route. The textured, uneven surface effectively renders scratches a non-issue. And considering the watch’s hardcore, toolish design, you wouldn’t mind putting a ding or two in this one.
