        The SEIKO 5 is a durable, reliable, and affordable automatic watch that has become a worldwide bestseller.

        Old Seiko 5 sports logo


        n 1968 when it first went on sale, the 5 stood for the following five points.
        1. Automatic winding
        2. Waterproof
        3. Day-date display
        4. Dia Flex(unbreakable spring)
        5. Dia shock (It won't break even when dropped)
        (According to The Seiko Book / Tokuma Shoten


        This is the same SEIKO 5 Sports with a newly designed logo.



        The meaning of the 5 has also changed.
        The new meaning of 5 is as follows:


        1. Automatic winding
        2. Waterproof
        3. Day-date display at 3 o'clock
        4. Crown at 4 o'clock
        5. Durable case & band


        Seiko has also introduced the military-style SEIKO 5 Sports.


        Although it is SEIKO 5 Sports, it also, unfortunately, has the crown at the 3 o’clock position. That aside, it still turned out really cool.


        The Military style comes standard with the crown at the 3 o’clock position, so lets let that one slide.

        English: MON, TUE, WED, THU, FRI, SAT, SUN
