Description
This Seiko is a quintessentially versatile 'daily wearer' from the turn of the millennium. It borrows design cues from high-end dive watches, such as the wave-pattern dial found on the Omega Seamaster Professional, but packages it in a slimmer, more affordable quartz format. Its thin profile allows it to slide under a shirt cuff, while the 100m water resistance makes it robust enough for weekend activity.
Key Features
Significantly textured wave dial, notched fixed bezel design, and 'Water Resist 100M' text which denotes a higher durability than standard dress watches.

Age Estimate
Produced circa 1998-2005, based on the font styles and the 7N42 movement cycle.
Cultural Significance
Represents the era when Seiko dominated the 'Mall Watch' market by offering higher-end aesthetic features (like textured dials) at reachable price points for the general public.
Condition Notes
Case shows significant honest wear with micro-scratches and some small impacts on the bezel edges. Successive scratches on the Hardlex crystal. The movement is assumed functional. Overall Grade: Good/Fair (Daily User).
Value Estimate
Market value is approximately $50 - $110 USD depending on the battery status and crystal clarity. Factors increasing value would be the original stainless steel bracelet.
Care & Maintenance
Battery replacement every 3-5 years. Gasket inspection is recommended if the watch is to be submerged. The Hardlex crystal can be polished with cerium oxide but is usually better to replace if scratches impede legibility.
