Rolex Day-Date 40mm Oyster Perpetual
The Rolex Day-Date 40mm Oyster Perpetual is a benchmark in luxury watchmaking, celebrated for its dual calendar display that shows both the full day of the week and the date. Since its introduction in 1956, the Day-Date has become an icon among professional and executive watches, with Rolex offering weekday displays in 26 different languages, catering to global collectors.

Caliber 3255 – Precision and Power
This year, the Day-Date 40mm features the new Caliber 3255 self-winding movement. Offering a remarkable accuracy of ±2 seconds per day, it surpasses the standard COSC rating of ±5 seconds. The upgraded movement provides an extended 70-hour power reserve, allowing wearers to remove the watch over the weekend and return on Monday without resetting. Dual barrels and a Chronergy escapement enhance both efficiency and durability, making it one of the most advanced movements in Rolex’s lineup.
Design and Materials
The 40mm case is available in platinum or 18K white gold. The platinum version features a unique ice blue dial with a subtle diagonal checkered pattern, while the white gold version comes with a prismatic bezel and Roman numeral hour markers. Both models showcase the classic Oyster case, polished to perfection, with a matching bracelet that balances elegance and robustness. The sapphire crystal ensures scratch resistance and clarity.
Wearability and Functionality
The Day-Date 40mm Oyster Perpetual combines functionality with style. The full-day display enhances practicality, especially for busy professionals, while the date window adds convenience. The watch maintains Rolex’s hallmark water resistance of 100 meters, making it suitable for everyday wear. Its versatile design makes it ideal for both formal occasions and casual elegance.
