【Black Seamaster, Arriving with Unyielding Spirit】OR Factory's new Seamaster 300m series. The 43

【Black Seamaster, Arriving with Unyielding Spirit】OR Factory's new Seamaster 300m 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: 1. Industry-exclusive ability to directly thread the crown onto the ceramic case, screwing the tube directly onto the ceramic shell, preventing it from falling off and providing superior water resistance. The case back is also screwed directly onto the ceramic shell; other factories require a steel inner tube. 2. First to create threads on the ceramic bezel, eliminating the need for a steel insert for rotation, resulting in a clearer sound. 3. Exclusive one-piece ceramic case, eliminating the need for a metal inner tube for water resistance; other factories use a steel inner tube within the ceramic case for waterproofing. Experience the original quality. —OR Factory
