Two-Tone Stainless Steel Case
This Seiko 5 automatic watch features a 43.00mm two-tone stainless steel case paired with a matching bracelet. The silver dial uses index markers and includes a day and date display at the three o'clock position. It is powered by the Caliber 7S26 automatic movement with 21 jewels. Water resistance is rated to 50m for everyday splashes and brief immersion.
Automatic Movement Sustained Operation
The Caliber 7S26 movement winds itself through natural wrist motion during daily wear, maintaining operation without manual winding or a battery. With 21 jewels reducing friction in the gear train, the movement is designed for consistent timekeeping over long periods. The fixed bezel and pull/push crown simplify the case construction for reliable daily function. No hacking or hand-winding capability is provided by this calibre.
Hardlex Crystal and Deployment Clasp
The Hardlex crystal protects the dial from scratches and impacts encountered in casual use. A deployment clasp secures the two-tone bracelet with a push-button release that reduces stress on the links. Stainless steel construction throughout resists corrosion from sweat and moisture within the 50m rating. The case back uses a pull/push crown design for straightforward time and date adjustment.

Questions about this item
Does the automatic movement need daily winding if I wear it all day?
The 7S26 calibre winds itself from wrist motion; wearing it all day keeps the mainspring charged without manual winding.
What strap size fits the supplied stainless-steel bracelet?
The bracelet uses a deployment clasp sized for the 43.00 mm case lugs; standard spring-bar straps of matching width will attach.
Will the Hardlex crystal and 50 m rating survive accidental splashes with older Seiko models I own?
Hardlex resists everyday knocks and the 50 m rating covers splashes and brief immersion, matching the protection on many vintage Seiko 5 references.
