The brushed and polished transitions on the lugs remain crisp, indicating it has not undergone excessive refinishing. (B)Dial Rating: 9.5 / 10 Excellent observations: no visible moisture damage/no dial discoloration/printing remains very sharp/clean chapter ring/date window aligned correctly/sub dial rings remain deep black The dial is one of the nicest aspects of this watch. (C)Lume: Rating: 9.5/10: Your Lume photo is surprisingly good. The luminous material: still glows evenly /hour plots illuminate uniformly/hands glow brighter than the indexes (normal for Seiko) Considering the watch is about 35 years old, this is excellent. (D)Bezel Condition: Very good. Only minor edge wear. The printed numerals remain crisp. No fading visibility. (E)Crystal: Only a few light surface scratches are visible. No chips. No cracks. Would benefit from a professional polish if desired. (F)Bracelet: Original private-market Seiko bracelet. Very little stretch. Clasp still closes correctly. This is a valuable feature because many Y182s have lost their original bracelets.

Plastic Movement Holder Still white/grey. No yellowing. No cracks. Another indicator of careful ownership. (H)Case Interior: The inside of the back case is unusually clean. Factory reset stickers are still present. Many examples have already lost this sticker. Collectors appreciate this. (I)Caseback: The engraving remains readable. Minor normal opening scratches only. No deep tool damage. This suggests careful service.
