Japan-Made Automatic Dress Watch

The Seiko 5 SNKN55J is a Japanese-built mechanical wristwatch driven by the 7S26 automatic calibre with 21 jewels. Its stainless-steel case measures 43.00 mm thick and pairs with a matching steel bracelet secured by a deployment clasp. A black dial with index markers shows the time, day and date through a Hardlex crystal.

Suits Daily Wear, Not Deep Water

Buyers wanting a reliable dress watch for office or casual use gain a self-winding movement, day-date complication and 50 m water resistance. Those who need a screw-down crown, ISO dive rating or a thinner case profile should look at a different specification.

43.00 mm Case Thickness Decides Fit

The 43.00 mm case thickness determines whether the watch sits flush under a shirt cuff or protrudes. Verify this dimension against your wrist and wardrobe before purchasing.

Questions about this item

How accurate is the 7S26 calibre with 21 jewels over a full day?

The automatic movement keeps time mechanically; actual daily rate varies with wear and position.

Does the 43.00 mm stainless-steel case and Hardlex crystal feel warm or make noise after hours on the wrist?

The watch is purely mechanical with no electronics, so it produces no heat and only a faint rotor sound when the arm moves.

What must I already own to start using the day-date display and deployment clasp?

Nothing extra is required; the watch arrives complete with bracelet, crown and movement ready to wear.
