Reference 116000-0012 presents the Oyster Perpetual 36 in a 36mm polished Oystersteel case paired with a smooth, fixed polished steel bezel and scratch-resistant sapphire crystal. The white dial carries luminous index markers and hands for clear readability, while the transparent case back offers a view of the movement within — an uncommon detail for the Oyster Perpetual line. A folding clasp secures the polished steel Oyster bracelet with its solid three-piece links.
Water resistance reaches 100 meters (330 feet / 10 ATM), supported by a screw-locked crown. The caliber 3130 self-winding movement delivers approximately 48 hours of power reserve and runs at 28,800 vph, featuring a Parachrom hairspring and Paraflex shock absorbers. Hours, minutes, and seconds are the sole functions — a deliberate, uncluttered approach to everyday wearability.
This is a pre-owned example of the 36mm Oyster Perpetual in its most essential configuration: no date window, no additional bezel function, and a versatile case size that transitions naturally between casual and formal settings. A straightforward expression of the core Rolex design language.
