The 5 Sports is Seiko’s entry automatic, and the 4R36 is the workhorse that made the category: a day-date automatic with hacking and hand-winding at a price that is hard to argue with. The 38 mm case wears well and the dial is clean and legible. Mineral crystal. It is the affordable automatic that punches far above its price. 38 mm, 12.1 mm thick, 44.2 mm lug-to-lug.
