This 31mm replica Datejust reproduces the classic with laboratory-level precision. The Oyster case is made of 904L stainless steel and 18K rose gold, and the bezel is inlaid with a white gold triangular groove pattern. The 6 top cubic zirconia diamond hour markers on the slate gray sun-grained dial are like falling stars. Each of them has undergone GIA-level cutting technology, and reflects the million-dollar fire under strong light. Equipped with a customized 2236 automatic mechanical movement, the Swiss Observatory-level adjustment achieves a daily average error of ?3 seconds, and the 55-hour kinetic energy storage keeps elegance forever. The five-bead chain head-type strap uses 3D laser engraving technology, and the hidden Easylink extension system is fine-tuned to adapt to the wrist in seconds with 5mm. The screw-in crown and 100-meter waterproof can face heavy rain and champagne baptism. The sapphire crystal mirror is coated with double-sided anti-reflective coating, and the diamond hour markers are injected with Swiss Super-LumiNova.
