The limited-edition Panerai Luminor Marina Carbotech Blu Notte sees the luxury dive watch maker pair its iconic case and legendary dial for the first time. The 44mm Carbotech case is forged from a solid carbon block while the Blue Notte dial sits above a P.9010 automatic movement whose twin barrels steadily release power over three days — not that you’d want to ever take it off for that long — all secured by a gorgeous alligator strap with titanium buckle.
