Seiko 5 Sports SRPD55
The 5 in Seiko 5 is a promise that goes back to the 1960s. Seiko's Sportsmatic 5 arrived in 1963 as Japan's first automatic day-date watch, and the name came to stand for five attributes: an automatic movement, a day and date display at 3 o'clock, water resistance, a recessed crown at 4 o'clock, and a case and bracelet built for durability. The 5 Sports line followed in 1968.
The SRPD55 still checks all five. Inside is the calibre 4R36, a 24 jewel automatic that also hand winds and hacks, with about 41 hours of power reserve. The day and date sit at 3, the crown sits at 4, and the 42.5mm steel case is rated to 100 meters under a unidirectional bezel, with a Hardlex crystal, and a see-through screw case back.
