What to know
Jacques Bianchi Marseille and former U.S. Navy diver Brock Stevens of Deepsea.EDC have developed the JB300 Professional around the demands of long underwater missions. Its 41.5 mm forged-carbon case uses a Grade 5 titanium inner core, while reinforced fixed lugs secure a pass-through strap. The left-side crown, fully graduated DLC-coated titanium bezel and 300-metre rating continue the functional direction established by the earlier JB300 Profonde.
The display separates critical timing information with two-colour Super-LumiNova: the bezel’s first 15 minutes and minute hand glow green, while the remaining markers glow blue. A COSC-certified Soprod P024 automatic movement replaces the standard-calibre approach of the previous collaboration. The edition comprises 500 numbered watches, with 200 reserved for military and police unit programmes and 300 offered publicly. The European product page lists €1,995 including tax, with public availability scheduled for 3 November 2026.
