French watchmaker Jacques Bianchi has collaborated with Brock Stevens, a former US Navy diver, to create the JB300 Professional, a dive watch designed for combat divers. The watch's design is influenced by the operational requirements of specialized units, with input from military personnel experienced in underwater interventions. The result is a timepiece that meets the needs of combat divers. The JB300 Professional features a 41.5mm diameter case made of forged carbon and grade 5 titanium.
The watch's construction is designed to withstand the demands of prolonged underwater missions. The case is 13mm thick and features a marbled appearance due to the forged carbon material. The watch also features a fixed bezel with a unidirectional rotating bezel made of grade 5 titanium, coated with DLC black. The watch is water-resistant up to 300 meters, making it suitable for professional diving. The JB300 Professional is powered by the Soprod P024 automatic movement, which has a 38-hour power reserve.
The watch's dial is designed for functionality, with a matte black surface and oversized indexes for easy reading. The watch features a distinctive luminescent treatment, with the bezel and dial having different colors to facilitate quick reading in low-light conditions. The watch also features a seconds hand with a red tip, adding a touch of color to the otherwise black dial. The JB300 Professional is designed to be a tool watch, with a focus on functionality and durability.
The Soprod P024 movement has a frequency of 28,800 alternations per hour and is certified by the Contrôle officiel suisse des chronomètres (COSC). The movement features a rotor that transforms wrist movements into mechanical energy, which is stored in the mainspring. The watch also has a manual winding mechanism and a seconds stop, allowing for precise time synchronization.
The JB300 Professional is limited to 500 pieces, with the first 200 reserved for collectors. The watch is priced at $1,950 and will be available for purchase on the Jacques Bianchi Marseille website starting November 3, 2026. The watch's price point is more accessible than other professional dive watches on the market, such as those from Omega or Tudor.
The JB300 Professional is the second collaboration between Jacques Bianchi and Deepsea.EDC, following the JB300 Profonde. The new watch has a stronger focus on military diving applications, with a design that reflects the needs of combat divers. The watch's launch is seen as a significant addition to the world of professional diving watches.
The partnership between Jacques Bianchi and Brock Stevens has resulted in a watch that meets the demands of professional divers. The JB300 Professional is a testament to the importance of collaboration between watchmakers and military personnel in creating functional and durable timepieces.
