This replica Datejust 126234 blue brings the sunburst blue dial to the classic 36mm case size, a combination that many collectors consider the definitive modern Datejust. The 126234 reference houses the latest-generation automatic caliber in a full Oystersteel case with a fluted white gold bezel, and pairs it with a Jubilee bracelet. At 36mm, this reference maintains the proportions that defined the Datejust when it first launched in 1945, updated with current-generation internals.

Case & Movement Specs

• Case diameter: 36mm
• Case material: Oystersteel (904L grade)
• Bezel: fluted white gold
• Dial: sunburst blue with applied luminous indices
• Crystal: sapphire with Cyclops magnification
• Bracelet: Jubilee five-link with Crownclasp
• Movement: automatic with quickset date

The 36mm case on this rolex datejust 36 wears larger than the number suggests because the fluted bezel and Jubilee bracelet add visual width beyond the measured diameter.

Caliber Breakdown

Inside the 126234, an automatic movement provides hacking seconds, quickset date, and around 70 hours of power reserve. The jump from the previous 116234 generation brought a longer power reserve and improved shock resistance, making the newer caliber a meaningful upgrade over its predecessor. Rolex kept the 36mm case dimensions nearly identical between generations, so the improvement is entirely mechanical rather than aesthetic. Compare the blue sunburst approach here against the 279135RBR Lady-Datejust 31mm, which takes the Datejust in a diamond-set direction. Both live within the Datejust lineup but represent very different buying intentions.

How It Compares

The debate between 36mm and 41mm Datejust never ends, but the 36mm maintains a loyal following among buyers who prefer vintage-inspired proportions on modern movements. Blue dials at 36mm read more compact and concentrated than on the 41mm variant, which spreads the sunburst pattern across a wider canvas. The Jubilee bracelet feels proportionally balanced at this size, neither too wide nor too narrow for the lugs. For anyone who believes the Datejust reached its best proportions decades ago, this replica Datejust 126234 blue proves that the original sizing still works.
