Product Identity

This is the Seiko 5 SNKL45K1, an automatic wristwatch with a 37 mm stainless steel case and matching bracelet. It runs on the calibre 7S26 movement with 21 jewels and shows the day and date through a black dial with index markers. The Hardlex crystal and 30 m water resistance complete the specification.

Who It Suits

The watch fits buyers wanting a mechanical dress watch with a silver-toned case and a deployment clasp. It is not suited to anyone needing a screw-down crown, a transparent case back, ISO dive certification or a case diameter larger than 37 mm.

Deciding Specification

The calibre 7S26 automatic movement with 21 jewels is the single spec that determines whether this is the right watch; it sets the winding method, jewel count and day-date function without offering manual winding or hacking seconds.

Questions about this item

Is the 37 mm case or 38 mm case thickness the right fit for my wrist?

The case measures 37 mm in diameter and 10.7 mm thick; the 38 mm figure in the specifications refers to overall case thickness including the crown, so choose based on the 37 mm diameter for wrist fit.

What does the 21-jewel automatic movement mean for daily wear?

The calibre 7S26 uses 21 jewels to reduce friction, self-winds from wrist motion, provides day and date with a Spanish option, and has luminous hands for low-light reading.

How far can I take the 30 m water resistance in practice?

Rated at 30 metres, it handles splashes, rain and hand-washing but is not suitable for swimming, showering or diving.
