Black Seamaster, a bold debut from Or factory's new Seamaster series. The 43.50m

Black Seamaster, a bold debut from Or factory's new Seamaster series. The 43.50mm case, bezel, and wave-patterned dial are all made of black zirconium oxide 1Zr021 ceramic. The skeletonized hands and the dot at 12 o'clock are coated with Super-Luminova. The movement's beauty is clearly visible. The 8806 movement can be admired through the sapphire crystal case back with its wave-edged design. Three exclusive technologies: First, it's the only factory in the industry to directly thread the crown onto the ceramic case, screwing the tube directly onto the ceramic shell. This prevents the crown from falling off and improves water resistance. The case back is also screwed directly onto the ceramic shell; other factories require a steel inner tube. Second, it's the first factory to create threads on the ceramic bezel, eliminating the need for a steel fitting and resulting in a clearer sound. Ddd's third feature is its exclusive full-shell ceramic design, eliminating the need for a metal inner liner for waterproofing. Other manufacturers use a ceramic shell with a steel inner liner for waterproofing. Ddd brings you the original feel. Or Factory DDD
