The Rolex Datejust 41 reference 126300 is the current-production all-Oystersteel Datejust 41 with smooth polished bezel, introduced at Baselworld 2017 to replace the discontinued Datejust II 116300. The 126300 represents one of the cleanest, most versatile Datejust configurations in the modern catalog — no two-tone treatment, no fluted bezel, just the architectural lines of the Oyster case in their purest form. The 41mm Oystersteel case carries a smooth polished bezel for an understated profile that wears equally well under a French cuff or with a t-shirt. The black dial features applied luminous-filled hour markers and Mercedes hands, the date at three magnified by the signature Cyclops lens, and the precision-set seconds hand driven directly by the movement. Powered by the in-house Rolex Caliber 3235 with paramagnetic blue Parachrom hairspring, Chronergy escapement, Paraflex shock absorbers, approximately 70 hours of power reserve, and Superlative Chronometer certification to -2/+2 seconds per day after casing. Water-resistant to 100 meters via the patented Twinlock screw-down crown and worn on the Oystersteel Oyster bracelet with Oysterclasp and Easylink 5mm comfort extension. Pre-owned in excellent condition.
