What is the history behind this timepiece? Everything started with a letter from a professional diver in Hiroshima prefecture of Japan. The diver explained that in depths greater than 300 meters, when using a diving capsule and saturation diving techniques, most watches get damaged. Answering this request, Seiko established a new development team. After years of research development, the world’s first Professional Diver’s 600m with titanium case was created. This model, along with other Seiko\'s is so called the Samurai by enthusiasts because of the sword-shaped hands on the original. Style: A black dial features a slightly raised pattern which is called a Tapisserie dial. This type of guilloche pattern that leaves lots of small squares on the surface of the dial, separated by thin channels. A machine called a pantograph \'traces\' the tapisserie pattern from a larger mock-up design and engraves an exact copy onto the smaller watch dial. Each dial can take between 20 and 50 minutes to engrave depending on the size and type of finishing. Around the edge of the dial are silver indexes alongside the the ever present Seiko logo at the 12 o\'clock position. Surrounding the dial is a silver stainless steel case alongside hardlex crystal glass ontop to provide it with the class and protection it deserves.
