Housed in a 36 mm round case of Everose Rolesor — Rolex's combination of Oystersteel and Everose gold — reference 126201-0016 follows the Oyster architecture's defining principles: a monobloc middle case, solid screw-down case back, and a screw-down winding crown featuring the Twinlock double waterproofness system. The result is water resistance to 100 metres / 330 feet. Above the case sits a domed bezel, while scratch-resistant sapphire crystal with a Cyclops lens magnifies the date display.
The white dial is accompanied by roman numeral hour markers and a date window at three o'clock. The three-piece solid-link Oyster bracelet shares the same Everose Rolesor composition as the case and fastens with a folding Oysterclasp fitted with an Easylink 5 mm comfort extension link.
Inside beats the perpetual, mechanical, self-winding Calibre 3235 — a Manufacture Rolex movement rated to a precision of -2/+2 seconds per day after casing, COSC certified, and offering approximately 70 hours of power reserve. Its oscillator features a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers, with bidirectional self-winding via a Perpetual rotor and stop-seconds for precise time setting.
