Automatic Movement with 21 Jewels
The Seiko SNK369K1 runs on the Calibre 7S26 automatic movement, winding itself through wrist motion. It contains 21 jewels to reduce friction and provides a power reserve of up to 43 hours. A day and date window at 3 o'clock displays both details in English or Spanish. This dress watch suits wearers who prefer mechanical tradition over battery power.
Sustained Daily Wear
The 37 mm stainless steel case measures 11 mm thick and carries a Hardlex crystal rated for 30 m water resistance. An 18 mm stainless steel bracelet secures with a deployment clasp for consistent fit. The movement maintains steady timekeeping across a full day without manual winding. The white dial with red accents and index markers remains legible under office or evening light.
37 mm Case Diameter
A 37 mm case diameter defines the wrist presence and determines whether the proportions suit the buyer. The fixed bezel and pull-push crown keep the profile clean. Buyers needing a larger dial, a screw-down crown or deeper water resistance should consider other models. The 21 jewel automatic engine and 43 hour reserve are fixed specifications.

Questions about this item
How much power reserve does the automatic 21-jewel movement give for all-day wear?
The Cal. 7S26 movement stores up to 43 hours of power reserve, so the watch keeps running through a full day and night without winding.
What strap size must the buyer already have if they want to swap the stainless-steel bracelet?
The bracelet uses an 18 mm lug width, so any replacement strap must match that 18 mm width to fit the case.
Will the 37 mm case and 30 m water resistance sit comfortably next to vintage dress watches in a rotation?
At 37 mm diameter and 11 mm thick with 30 m water resistance, it matches classic dress-watch proportions and handles light splashes like older pieces.
