A Seiko 5 watch comes with a set of expectations. If it’s wearing the badge on the dial, you know that you’re getting a no-nonsense timepiece, one that’s both reasonably priced and robustly built to Seiko’s exacting standards. The “5” references a set of key attributes that first defined the line: automatic winding; the day/date displayed in a single window; water resistance; a recessed crown at the four o’clock position; and a durable case and bracelet. Of course, much of this is already part and parcel of modern watches, so today these bullet points are more of a spiritual guide for the Seiko 5 line rather than a strict checklist. Nevertheless, if it’s a Seiko 5, you know you’re getting a workhorse that punches way above its weight.
Today, we’re going hands-on with a watch Seiko brought out last year and, like many of their lower-tiered releases, it went by largely unnoticed—introducing the Seiko 5 Sports “Diastar,” reference SSA285K1.
