Rolex Datejust 36 36 mm 126234BLDJ Steel/White Gold Blue

The Rolex Datejust is one of the most recognizable and enduring watch designs in horological history, having introduced the first self-winding wristwatch to display the date in a magnified aperture at 3 o'clock when it debuted in 1945. Over successive generations Rolex has refined every detail while preserving the model's essential character—clean symmetry, robust Oyster construction, and the instantly legible date window crowned by the signature Cyclops lens. Reference 126234BLDJ represents the current generation of the 36mm Datejust, inheriting all of that legacy while benefiting from the latest advances Rolex has incorporated into the line.

The 36mm Oyster case of the 126234BLDJ is constructed in Rolex's proprietary Oystersteel—a 904L stainless steel alloy prized for its exceptional corrosion resistance and mirror-bright polishability—complemented by 18k white gold on the bezel and crown, giving the watch its two-tone character without veering into ostentation. The 18k white gold fluted bezel is one of Rolex's most storied design signatures, originally conceived to give the Datejust a formal, jewelry-inspired edge; its precisely machined facets catch the light and frame the dial with understated brilliance. Water resistance is rated to 100 meters (330 feet), making this a genuinely versatile everyday companion.

The blue dial of reference 126234BLDJ is a perennial favorite among collectors, conveying depth and sophistication that shifts character depending on the light—appearing near-navy in shadow and a rich cobalt under daylight. Blue dials on white-gold-bezeled steel Datejusts have historically commanded strong secondary-market interest, underscoring how well this color pairing resonates with buyers worldwide. The Cyclops date lens at 3 o'clock ensures effortless legibility, a practical detail that makes the watch as functional as it is beautiful.

The Jubilee bracelet—introduced alongside the original Datejust in 1945 and exclusive to the model for many years—features five-piece links that create a supple, dressy drape on the wrist quite unlike the sportier Oyster bracelet. Rolex manufactures the bracelet to the same exacting tolerances as the case, and the Oysterclasp with its Easylink comfort extension system allows the wearer to adjust the bracelet length by approximately 5mm without tools, accommodating changes in wrist size throughout the day. Together, the Jubilee bracelet and fluted bezel give the 126234BLDJ a thoroughly polished aesthetic that bridges casual and formal occasions.

Powering the watch is a Rolex automatic movement, ensuring the self-winding reliability and precision that have made Rolex a benchmark for the industry. The movement is fully integrated into the Oyster case, hermetically sealed to protect the caliber from moisture, dust, and pressure, and the combination of Oystersteel case and screw-down Triplock crown contributes to the watch's 100-meter water resistance. Rolex's strict internal standards mean every movement is tested to performance levels that exceed the official Swiss chronometer certification.
