Seiko history began in 1881 when Kintaro Hattori established the K. Hattori retail and repair store. In 1892 Seikosha was established making wall clocks. 1895 saw the production of their first pocket watch. 1913 saw the launch of their first wristwatch, the Laurel. In 1924 the first Seiko was manufactured. Daini Seikosha (now Seiko Instruments Inc.) established in 1937. Seiko listed on the Tokyo stock exchange in 1949. The Suwa factory became independent and formed Suwa Seikosha Co., Ltd. (now Seiko Epson Corporation in 1959). First introduced as the Seiko Sportsmatic 5 in 1963 it became an instant bestseller for Seiko. Seiko 5 is the longest continuously running sub-brand in the Seiko family. The 5 stands for the watches 5 principle attributes: Diaflex (unbreakable mainspring), Diashock (Seiko's shock-resistant design, equivalent to the Swiss "Incabloc"), Automatic winding, day/date indication, and Water-resistant. In 2019 Seiko decided to modernise the Seiko 5 changing the logo to a stylised “S” and creating 5 categories Sports, Suits, Specialist, Street, and Sense. Each model has the aesthetics of the past but with an added flourish of modernism.
Our Seiko 5 SRPD77K1 is in the Sports category, it has a 42.5mm stainless steel case and has a proprietary Seiko gunmetal hard coating. The case design is very similar to the Seiko SKX models.

Personally, I am a big fan of the "5KX" series as it gives you everything want when modding an SKX but a fraction of the price, that to me is a good deal! Granted, you don't have the screw-down crown, the ISO certification, and all the other bells and whistles you had with the SKX, but how many of us really ever needed those added features? I personally would rather more designs, and some truly great designs at that, than the same SKX for more years...
