The seller represents this timepiece as being in vintage condition, showing age-appropriate superficial scratches and nicks, and the original silver dial has developed a warm honey-cream/champagne patina with brown and amber staining, white crystalline deposits, aged lume, and darkened hands. The leather strap is aftermarket. It has a personalised engraving on the case back. It includes the boxes (inner and outer), additional items, and papers dated 1989.

This is an incredibly unique, fully documented neo-vintage Datejust 16220. The ref. 16220 with the engine-turned bezel offers a distinctly classic character that the standard fluted bezel cannot replicate. What separates this specific example is its unpolished case, striking natural dial transformation, and verifiable, three-point corporate provenance tied to one of America’s historic industrial companies. Over 35 years, it has undergone a dramatic transformation due to tritium degradation, shifting from silver to a warm honey-cream/champagne tone. There is heavy brown/amber organic staining concentrated in the upper quadrant (10–2 o’clock zone), particularly around the applied Rolex coronet. Multiple white crystalline mineral deposits are scattered across the dial surface, creating a “stardust” effect. The applied baton indices are structurally intact, consistent with aged, degraded tritium lume, and the hands show matching age-appropriate darkening. Meyer Material Company was a historic Chicago-area ready-mix concrete and aggregates company, founded in 1920 and operated for decades under the Pritzker family dynasty. This watch was an official corporate presentation gift awarded to Richard E. Dohnke in 1989 to commemorate an incredible 35 years of service.
