Estate fresh Seiko Sportsmatic SilverWave automatic wristwatch, reference 6601-7991. Black dial with SilverWave branding, stainless steel case, and 17-jewel automatic movement.

The watch will start running after being gently shaken and the seconds hand begins moving. I have not performed any further testing and cannot guarantee accuracy, service history, power reserve, or long-term operation.

The most notable issue is the cracked crystal, with additional scratching and wear throughout. The case shows age-related scratches and wear from use. No strap or bracelet is included.

Caseback marked 6601-7991 with serial number 5N00146.
