Highly recommend the S Factory Seamaster 300m diving watch, exclusive deck quality available online. The movement features a brand new original Japanese Citizen fully automatic mechanical movement paired with the latest 8800 deck, made of all-metal and genuine gemstone eyes! It truly achieves zero repairs, precise timing, and a combination of practicality and aesthetics! It is 100% waterproof. The glass is high-definition double anti-reflective sapphire crystal. The ceramic bezel uses imported ceramic combined with a 12 o'clock sapphire moonlight pearl (beautiful and high-end). The hands are coated with Super-LumiNova, featuring blue-green dual-color luminescence, with the minute hand in green luminescence to match the green luminous dot on the bezel for diving oxygen countdown. The dial corresponds to the boutique Seamaster 300 ceramic surface craftsmanship, visually stunning compared to ordinary oil pressure. The case is made of 316L stainless steel and is equipped with the only original one-way rotating timing bezel in the same class. The case side features a pressure relief valve consistent with the original. The case dimensions are 42/11mm, officially perfect size. Please recognize the case back ear position code: 89238899.
