About the Seiko Men's Series 5 Automatic Watch

The Seiko 5 is a mechanical automatic watch with a 38mm stainless steel case, a blue dial and a date window. It winds itself from the motion of your wrist and needs no battery. The 38mm case is smaller than most men's sports watches, so it wears neatly on slim wrists and under a shirt cuff. Owners rate it highly for its reliability and classic looks at an entry-level mechanical price.

    Questions and answers

    Does it need a battery?
    No. It is an automatic mechanical watch that winds itself as you move your wrist. If it stops, shake it gently or wear it to restart.
    Can I swim with it?
    Yes. It is rated to 10 ATM (100m), which covers swimming and showering. Avoid pressing the crown underwater and skip deep diving.
    How does it compare with the Seiko 5 Sports?
    The 5 Sports line uses larger cases and sportier styling. This model is smaller and dressier, better for slim wrists and office wear.
    What is in the box?
    The watch on its stainless steel bracelet, usually with a manual and warranty card. Check the listing for the exact contents.
    Is 38mm too small for a man?
    It suits slim to average wrists and reads as a classic dress size. Men with larger wrists may prefer a 40mm or bigger case.
