Omega Seamaster series diving watch with case back and warranty card, featuring a dual certificate. It is equipped with Omega's unique original 8800 automatic mechanical movement. The watch has a diameter of 41mm, a thickness of 10mm, and comes with a date function. The case is made of 316 stainless steel, and the bezel is unidirectionally rotatable. The watch features a sapphire crystal glass and a screw-down stainless steel crown.First and foremost, this is a diving watch, so it naturally includes essential diving functions such as luminous features, deep water resistance, and underwater timing capabilities. However, what I want to emphasize about this watch is the quality feel it provides once you wear it. Unlike some other brands, the Seamaster feels more comfortable and natural on the wrist. The connection between the wrist and the watch increases rapidly as soon as you put it on. A great watch requires not only the perfect design from the designer but also high-quality materials to reflect its value. This is a good product that is worth having.
