Rolex Explorer II Polar “Chicchi Di Mais” Heavy Patina Original Owner 1991 (Box/Service Papers/Unpolished)

Rolex Explorer II 16570 “Chicchi Di Mais” Corn Dial 1991

Rolex is one of the most influential names in Swiss watchmaking, known for its focus on durability, precision, and purpose-built design. Since its early years, the brand has created watches that serve specific functions—from diving to aviation to exploration—earning a reputation for reliability in demanding environments. This commitment to robust engineering and distinctive aesthetics has made Rolex a benchmark for professional tool watches across generations.

The Explorer II Ref. 16570 continues this legacy as a model designed for adventurers who require clarity and dependability in low-light or extreme conditions. Introduced in the late 1980s, the reference features a fixed 24-hour bezel and a dedicated GMT hand, allowing wearers to distinguish day from night—an essential feature for cave explorers and field researchers. Early white-dial variants, particularly the celebrated “Chicchi Di Mais” (corn) dials, have become highly regarded for their rich and unusual patina. The 16570 blends utility, durability, and distinctive character, making it a standout within Rolex’s lineup and a favorite among collectors who appreciate untouched, original examples.

The standout feature is the gorgeous white “Chicchi Di Mais” (corn) dial, prized for its rich patina. The indices have developed a deep yellow to warm brown tone, evenly aged and beautifully contrasted by the crisp white hands.
