Description: Rolex Oyster Perpetual 277200 Pre-owned Rolex Oyster Perpetual ref 277200 (2026). The Oyster Perpetual is where everything started for Rolex. Time-only, no date, no extra complications. Just a clean dial, automatic movement, and the waterproof Oyster case that laid the foundation for the brand’s reputation. It’s been part of the lineup since the 1930s, and the formula hasn’t really changed. What has evolved is the use of color, especially in recent years.
