Our take on the Seiko 5 Sports Automatic

The Seiko 5 Sports Automatic is a mechanical field-style watch with an in-house automatic movement, a 37.4mm case and day-date display. It is the smaller, more wearable take on Seiko's long-running affordable automatic line, aimed at people who want a real mechanical watch without a luxury price. At $390.50 at Mani Jewellers as of November 5, 2026, it sits at the top of its recent range, so this is not a bargain moment.

Questions and answers

Is the Seiko 5 Sports Automatic worth it?
For a first mechanical watch, yes. You get an in-house automatic movement and a wearable 37.4mm case, though at $390.50 at Mani Jewellers as of November 5, 2026 you are paying near the top of its range.
Is 37.4mm too small for a men's watch?
No. 37.4mm is a classic mid-size that suits wrists under about 7 inches and reads larger on a strap than the number suggests. It is also a good fit for women who want a mechanical watch.
How accurate is the automatic movement?
Expect roughly -20 to +40 seconds a day, Seiko's stated range for its 4R movements. That is normal for an entry automatic and easy to correct once a week.
Does it need a battery?
No. It winds from wrist movement and has a power reserve of about 41 hours, so it stops if left off the wrist for a couple of days.
Is it waterproof enough for swimming?
It is water resistant, but check the depth rating on the caseback before swimming. For pool use you want at least 100m; for showers and handwashing it is fine.
When is it cheapest?
Seiko 5 prices dip during seasonal sales and when a new colorway launches. At $390.50 as of November 5, 2026 it is near its recent high, so waiting for a markdown is reasonable.
Where is the Seiko 5 Sports Automatic cheapest?
At Mani Jewellers, for $390.50, as of our latest check.
What do buyers say about the Seiko 5 Sports Automatic?
Rated 4.9 out of 5 from 108 ratings.
