Seiko 5 Automatic Watch 37mm

The Seiko 5 SNKK27K1 is an automatic wristwatch with a 37 mm stainless steel case and a matching bracelet. It runs on the Caliber 7S26 movement with 21 jewels and shows the time, day and date through a mineral crystal. Water resistance is rated to 30 metres.

Dress style for daily wear

The blue dial with quarter-speed look and silver-tone indices suits office or casual settings where a classic analog face is preferred. Buyers needing higher water resistance for swimming or diving should look at another model. Those wanting a lighter titanium case or a sapphire crystal will not find those materials here.

Caliber 7S26 21-jewel movement

The automatic movement winds from wrist motion and holds 21 jewels to reduce friction. It powers the centre hands plus day and date windows at the three o'clock position. A see-through case back reveals the rotor, while the fold-over deployment clasp secures the bracelet.

Questions about this item

How much daily winding or motion does the Caliber 7S26 automatic movement need to keep running overnight?

The 21-jewel Caliber 7S26 winds itself from wrist motion; wearing it for a normal day typically stores enough power to run through the night, and placing it crown-up when idle helps maintain accuracy.

What strap tools or extra links are required to size the stainless-steel bracelet with its deployment clasp?

The bracelet uses a fold-over deployment clasp with removable links; a standard spring-bar tool or pin pusher is all that is needed to add or remove links for a proper fit.

Will the 37 mm case and 11 mm thickness sit comfortably under a dress shirt cuff alongside older, thinner watches?

At 37 mm diameter and 11 mm thick, the stainless-steel case is slim enough to slide under most cuffs, and its fixed bezel and mineral crystal keep the profile low compared to many vintage pieces.
