Origin & Provenance
Japan/Malaysia/Singapore (Seiko's global manufacturing sites). Movement is a 100% in-house Seiko design.
Age Estimate
Circa 2010-2020. This specific dial layout and 7S26 movement version (likely 7S26C) suggest modern production before the line was transitioned to the 4R36 movement.
Cultural Significance
A cornerstone of the 'affordable mechanical' movement. It proved that a reliable, in-house mechanical watch with a stunning dial could be produced for under $150, influencing a generation of watch enthusiasts.
Condition Notes
Very Good. The case shows minor hairline scratches on the polished surfaces. The dial and hands are pristine. Bracelet shows typical 'Seiko jingle' but appears to have all original links.
Value Estimate
MSRP originally around $125-$150. Current secondary market value is $110 - $180 depending on condition. Prices have risen slightly since the 7S26 movement was discontinued in favor of the 4R-series.
Care & Maintenance
Service every 5-7 years. Avoid strong magnetic fields. As it lacks hand-winding, use the 'Seiko Shuffle' (gentle horizontal shaking) to start the movement. Clean the bracelet with a soft brush and water.
