- Highly recommend the S factory Seamaster series 300m diving watch, an exclusive quality found only online. The movement is equipped with a brand new Japanese imported Citizen fully automatic mechanical movement, achieving zero repairs, accurate t.mes
keeping, and strong practicality with 100% waterproof capability. The glass features high-definition double-sided sapphire glass, and the ceramic bezel is made of imported ceramic, complemented by a 12 o'clock sapphire moonlight bead (aesthetic and premium). The hands are coated with Super-LumiNova luminescent paint, featuring blue and green dual-color luminescence, with the minute hand displaying green luminescence in conjunction with the green luminescent dot on the bezel for diving oxygen countdown. The dial corresponds to the boutique Seamaster 300 ceramic surface process, visually surpassing ordinary oil pressure. The case is made of 316L stainless steel, featuring the only ceramic original unidirectional rotating chronograph bezel in its class. The side of the case has a pressure relief valve consistent with the original model. The dimensions are 42/11mm, perfect according to official specifications. Please recognize the case back ear position code: 89238899.
