King Seiko 56KS 5621-7020 No Date
While most of the King Seiko watches were produced by the Daini factory, 56KS was produced by the Suwa factory instead and it shared the Cal.56XX movements with 56GS (56GS was adjusted to be more accurate though). This 56KS here is rare due to the absence of date/day display, and it creates a symmetric and simple dial which is best for minimalists. Moreover, it has a one-piece case that can only be found in the early examples of 56KS and 52KS. By making the movement only accessible from the top of the watch, it provides greater protection against moisture and dust and thus further enhances robustness of the watch.
