Casual Automatic Timepiece

This Seiko 5 automatic watch suits adults who want a reliable mechanical watch for everyday wear. The Caliber 7S26 movement with 21 jewels runs at 21600 vph and stores roughly 40 hours of power reserve. A black dial carries luminous hands, index markers and Arabic numerals at 6, 9 and 12 o'clock. Date and day windows sit at 3 and 6 o'clock respectively.

Thermals Noise Power Not Applicable

As a purely mechanical device the watch generates no heat, emits no audible noise and draws no electrical power. The automatic rotor winds the mainspring through natural wrist motion so no battery or charging is required. Hardlex crystal protects the dial from scratches while the screw-down transparent case back reveals the movement. Water resistance is rated to 30 meters for splashes and brief immersion.

Stainless Steel Bracelet Integration

The 38 mm round case measures 11 mm thick and fits an 18 mm stainless steel bracelet secured by a fold-over clasp with push-button release. Fixed bezel and pull-push crown keep the profile clean for dressing up or down. No specific case size or strap adapter is needed; the integrated bracelet completes the build out of the box. Buyers needing a leather or NATO strap must source spring bars separately.

Questions about this item

How do I set the day and date on the Caliber 7S26 movement?

Pull the crown to the first click to adjust the day and date, then pull it to the second click to set the time; many users forget the first click exists.

What future service does the automatic movement require?

The Caliber 7S26 with 21 jewels needs a full movement service every three to five years to replace aged lubricants and check water resistance seals.

What is the first limit I will hit if I wear this watch continuously for several days?

The 40-hour power reserve will run out if the watch stays off the wrist for more than about a day and a half, stopping the movement until it is wound again.
