Seiko diver's watches are perfect for entry-level divers. It is one of the three largest watch factories in Japan, and its mechanical technology is world-famous. In the machinery industry, it is the only company selected as one of the world's top 100 sustainable enterprises. Seiko was also the first manufacturer in Japan to design and produce bearings. In 1969, Seiko turned the history of world timekeeping upside down with the introduction of the world's first analogue quartz watch. Most of Seiko's diver's watches are waterproof at a depth of 200 to 1000 meters, which can be said to be an entry-level diver's watch, with accuracy and waterproofness at the thousand-yuan budget level, which is a cost-effective product.
