The true spirit of a dive watch is forged not in a marketing office, but in the trenches of real-world application. The Jacques Bianchi Marseille x Deepsea EDC collaboration is a magnificent testament to this principle, born from the shared ethos between the storied French brand and U.S. Navy Diver Brock Stevens of Deepsea EDC.
This timepiece, the JB300 Profonde Titanium, is not just an homage to exploration; it is an uncompromising, limited-edition tool built for absolute precision, celebrating the kinship found in demanding environments.
Limited to just 150 individually numbered units, this collaboration immediately stakes its claim as a rare and desirable artifact for the dedicated collector. Its construction is centered around an exceptional material: Grade 5 titanium (Ti-6Al-4V). This choice is critical, ensuring the 41.5mm case is robust, lightweight, and highly corrosion-resistant—the ideal trifecta for professional use whether beneath the waves or in the field.
With a slender 12.5mm thickness and a compact 44mm lug-to-lug measure, the watch maintains a commanding presence without ever feeling cumbersome, an impressive feat for a purpose-built 300-meter diver.
Powering this rugged architecture is the proven Swiss-made Soprod P024 automatic movement. This calibre is renowned for its reliability and keeps the dial beautifully clean by offering a simple hours, minutes, and seconds display without the added clutter of a date window.
The crown, an essential component for securing the formidable 300m water resistance, is deliberately screwed down and placed at the 9 o’clock position—a classic ‘destro’ configuration that prevents accidental pressure on the wrist during demanding operations.
The dial is where the watch truly signals its mission. The black “Maxi Dial” layout prioritizes legibility, yet incorporates a crucial duality: a functional, yellow 24-hour scale for quick reference in low-light environments.
Adding further technical sophistication is the intelligent application of Super-LumiNova®. The applied indices glow a cool blue emission, while the minute hand and the crucial bezel pearl glow a distinct green emission, ensuring directional orientation and elapsed dive time remain instantly legible, adhering strictly to the codes of safety and precision.
Delivered on a custom JBM green strap, and currently available for €1,162.50 during the pre-order period, the titanium JB300 Deep is an absolute statement of durability and purpose for the few who appreciate what lies beneath the surface.
