Seiko 5 Automatic Dress Watch

The Seiko 5 SNK361K1 is a new automatic dress watch for men who value mechanical tradition in a steel bracelet. Its round black dial and analog display suit formal or daily wear without needing a battery. The stainless steel case and band deliver a cohesive silver-and-black look.

20 mm Stainless Steel Band

The 20 mm stainless steel band with a fold-over clasp determines whether this watch fits your wrist and matches your preferred fastening style. A 9-inch band length sets the maximum circumference before links are removed. If you need a leather strap, rubber band or a different lug width, this model will not meet that requirement.

Date Window and Bar Markers

The date window at three o'clock adds daily utility without a chronograph complication. Applied bar markers replace numerals for a clean dress aesthetic. No additional software, apps or bundled tools are included; the watch functions purely as a mechanical timepiece.

Questions about this item

What does the 20mm band width mean for strap choices?

The 20mm lug width matches many aftermarket leather, rubber or metal bracelets, so you can swap the original stainless bracelet without needing custom parts.

How does the automatic movement run without a battery?

A rotor winds the mainspring as you move your wrist; the watch stores enough energy to keep running overnight or through a typical workday off the wrist.

Will the 9-inch bracelet fit a larger wrist?

The 9-inch stainless bracelet uses a fold-over clasp with micro-adjust holes, allowing several millimetres of fine-tuning for a secure fit on most adult wrists.
