Circa 1990-1995 based on the 7T34 movement production cycle
Cultural Significance
Represents the 'Techno-Logic' era of Japanese watchmaking where multi-function quartz movements replaced mechanical movements for professional aviators.
Condition Notes
Good with visible signs of wear. Notable gold-tone thinning ('brassing') on the high points of the scalloped bezel and crown edges. Heavy wear on the original plating reveals a duller base metal underneath.
Value Estimate
Market Value: $150–$300 USD; negligible melt value as it is not solid gold.
Care & Maintenance
Avoid polishing cloths containing abrasives as they will remove the remaining gold plating; clean with a damp microfiber cloth only.
