JB300 INDIGO MARIS
Jacques Bianchi Marseille reinterprets its legendary military dive watch, the JB300 Indigo Maris.
Jacques Bianchi Marseille enriches the JB300 family with a new limited edition: the JB300 Indigo Maris, produced in 150 numbered examples. This reference continues the JBM tradition: a diving watch conceived as an instrument, built upon a proven technical architecture, and defined by a distinctly maritime identity.
The JB300 case, machined from Grade 5 titanium, retains the proportions that have established the coherence of the collection: 41.5 mm in diameter and 13 mm in thickness, with a 20 mm lug width. A format designed for purpose, maintaining a balance between presence, comfort, and legibility.

Grade 5 Titanium: Brushed and Polished Finish.
For this edition, Jacques Bianchi Marseille introduces a brushed and polished execution, crafted to highlight the geometry of the case. The satin-finished surfaces structure the volume, while the polished edges accentuate the architecture. The ensemble offers a more sculptural expression of Grade 5 titanium, while preserving the material’s intrinsic qualities: lightness, strength, stability, and comfort.
INDIGO MARIS DIAL: LEGIBILITY AND DEPTH
The JB300 Indigo Maris is distinguished by a dial developed around a dense, maritime hue, conceived to deliver depth and contrast in all lighting conditions.
The display architecture remains faithful to the fundamentals of a serious diving instrument: generous hour markers, bold hands, and immediate visual reference points. Luminescence is ensured by Super-LumiNova® BGW9, providing a blue emission in darkness and clear legibility, even in low-light environments.


The JB300, Rich in History
1990s, diving and reimagined design:
the JB300 INDIGO MARIS defines its era.


super-luminova®
Since our inception, visibility has been one of Jacques Bianchi Marseille’s signature features. The JB300 Indigo Maris transcends the darkness, offering unparalleled legibility through the meticulous application of Super-Luminova® on the "Maxi Dial" indexes and hands. This luminescent coating ensures perfect clarity, even in the deepest depths, providing optimal readability.
The blue textured dial, sleek and functional, minimizes glare, while the light emitted by the luminescent elements guides each dive with precision. A true blend of technical performance and refined aesthetics, making the JB300 Indigo Maris an exceptional timepiece, designed to illuminate your underwater exploration.
