The Rolex Datejust 41 reference 126300 is the all-Oystersteel, smooth-bezel expression of one of horology's most quietly influential watches — the watch that introduced the date-at-three complication to the wristwatch in 1945 and has continued to define classical wristwatch design ever since. The 126300 was introduced as part of the 2016 Datejust 41 generation to complement the fluted-bezel 126334, giving the 41mm Datejust line a cleaner, sportier expression in the same modern case. This 2026 example carries the Azzurro Blue lacquer dial — a vibrant sky-blue dial option in the current Datejust 41 lineup with applied Roman numerals — paired with the five-link Jubilee bracelet originally designed in 1945 specifically for the very first Datejust. The 41mm Oystersteel Oyster case features the polished smooth Oystersteel bezel and the cyclops-magnified date at 3 o'clock. Powered by the in-house Rolex Caliber 3235 self-winding chronometer movement with the patented Chronergy escapement for improved efficiency, paramagnetic blue Parachrom hairspring, Paraflex shock absorbers, and a substantial 70-hour power reserve, the 126300 carries Superlative Chronometer certification to -2/+2 seconds per day. Sapphire crystal, screw-down Twinlock crown, 100 meters water resistance. 2026 production.
