- Highly recommend the S Factory Seamaster 300m diving watch, exclusively available online with top-notch quality. The movement is equipped with a brand new Japanese original imported Citizen automatic mechanical movement, achieving zero repairs, precise t.mes
keeping, and strong practicality, with 100% waterproof capability. The glass is made of high-definition double anti-reflective sapphire glass. The ceramic bezel uses imported ceramic paired with a 12 o'clock sapphire moonlight bead (aesthetic and high-end). The hands feature a Super-LumiNova luminescent coating, with blue-green dual-color luminescence; the minute hand displays green luminescence, complemented by a green luminescent dot on the bezel for diving oxygen countdown. The dial matches the boutique Seamaster 300 ceramic surface craftsmanship, delivering visual effects that surpass ordinary oil pressure. The case is made of 316L stainless steel, featuring the only original ceramic unidirectional rotating timing bezel in its class. The side of the case includes a pressure release valve that matches the original. The case diameter is 42mm with a thickness of 11mm, perfectly sized according to official specifications. Please recognize the bottom cover ear code: 89238899.
