Design and Craftsmanship

This Datejust presents a 31mm Oystersteel case complemented by a fluted white gold bezel, embodying White Rolesor—a Rolex hallmark uniting steel’s durability with gold’s luster. The pink dial features a sunray finish, where precise brushing creates radiating grooves for subtle, shifting light reflections that enhance the soft pink hue. Applied via Physical Vapour Deposition or electroplating and sealed with varnish, it delivers vibrant depth and a characteristic glow. The date at 3 o’clock is magnified by the Cyclops lens, while scratch-resistant sapphire crystal safeguards these refined details—exemplifying Rolex’s expertise in dial artistry and aesthetic perfection.

At its heart lies the automatic Calibre 2236, fully manufactured by Rolex watches, achieving Superlative Chronometer precision (-2/+2 seconds per day after casing). Incorporating a Syloxi hairspring in silicon for exceptional stability and magnetic resistance, high-performance Paraflex shock absorbers, and bidirectional Perpetual rotor winding, it offers an approximate 55-hour power reserve. Centre hour, minute, and seconds hands with stop-seconds function provide reliable, precise timekeeping for any occasion.
