Pure Oyster Perpetual, reference 116000 distills Rolex's core formula into a clean, time-only sports watch with understated collector appeal. This watch pairs a 36mm stainless steel case and bracelet with a black concentric dial that gives the familiar layout added depth and texture. Its automatic movement keeps the focus on simplicity and everyday utility rather than complication. At 11.6mm thick, it wears with the compact, balanced proportions that make the 36mm Oyster case so enduring.
