STEEL BACK A904-5009 A2, WATER RESISTANT, serial 542214. Matching Seiko SQ-marked folding clasp and bracelet endlinks stamped Z1254. Provenance: Authentic vintage 1980s Japanese quartz digital production from Seiko, sourced from an estate collection. Condition: Watch has a new battery and display is fully functional. However, only the top right button works, and the others do not respond, so time cannot be set. Watch is being sold for parts or repair. Shows visible surface wear throughout including scratches on the crystal and case, plating wear/brassing on edges, clasp, and band links, and minor residue around pushers.
Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.
Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.
Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.
Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
