Built on generations of excellence, Le Jour timepieces reflect strict Swiss manufacturing standards, undergoing rigorous quality control for ultimate reliability.
A purpose-built instrument for life across hemispheres. The Hammerhead GMT integrates a 24-hour complication with a bidirectional ceramic bezel, delivering continuous dual-zone legibility above and below the surface. Encapsulated in a brushed and mirror-polished steel cushion case, the ergonomic contours complement its robust 200-meter water resistance, offering a sophisticated, low-profile silhouette engineered for effortless transition between deep water and international traveling.
Anchored by a subtle canvas-textured surface, the dial creates a soft, light-absorbing background that elevates its polished, raised indices and faceted hands. The central GMT hand provides a sharp visual anchor for instant dual-time reading. Applied generously with Swiss Super-LumiNova, the display ensures effortless low-light legibility, balancing tactile surface detail with pure horological functionality.
At the heart of the Hammerhead GMT beats the Swiss Sellita SW330 automatic movement, operating at 28,800 bph across 25 jewels. Equipped with an independent 24-hour complication module, it enables seamless dual-time tracking without sacrificing power delivery. Anchored by a solid steel caseback featuring a high-relief hammerhead motif, the construction is rated to 20 bar (200 meters) - a rigorous synthesis of Swiss precision and ocean-going durability.
