Automatic movement for daily wear

The Seiko 5 Sports SNK615K runs on the 7S26 automatic calibre with 21 jewels. A stainless steel case and matching bracelet hold a blue dial with luminous hands and indexes. A day and date window sits at three o'clock. It is built for men who want a mechanical watch that stays running through normal daily motion.

30-metre water resistance and Hardlex crystal

The Hardlex crystal protects the dial from everyday knocks. Water resistance is rated to 30 metres, which covers hand-washing, rain and accidental splashes. It is not intended for swimming, showering or any submersion. The crown is not screw-down, so moisture can enter if the watch is pressed under water.

Upgrade from battery quartz or fashion watches

Buyers replacing a quartz watch gain a self-winding movement that needs no battery changes. The solid bracelet and deployment clasp replace thinner straps that wear quickly. The jump is worth it if you value mechanical operation and a metal build over slimness or deep-water rating. Collectors needing a screw-down crown, higher water resistance or a hacking movement should look elsewhere.

Questions about this item

Will the 37.00 mm case fit under the cuff of a dress shirt I already own?

At 37.00 mm diameter the stainless steel case sits close to the wrist, so most standard shirt cuffs will close over it without catching.

How do I confirm the 7S26 automatic movement is keeping time correctly after I start wearing it?

Set the time, wear the watch for a full day, then compare it with a reliable reference; the 21-jewel 7S26 calibre typically runs within a few seconds per day when fully wound.

Does the box include the stainless steel bracelet with deployment clasp or must I buy a strap separately?

The watch ships on its original stainless steel bracelet fitted with the deployment clasp, so no additional strap purchase is required.
