Oyster Perpetual Day-date 40, Knockoff Designer Watches

Bold innovation and excellence

The Oyster Perpetual Day-Date 40 (Oyster Perpetual Day-Date 40) 950 platinum model is equipped with a striking ice blue dial and a triangular fluted bezel for the first time. This exquisite element is the cornerstone of Rolex’s aesthetic heritage, and it is only used in some classic models of the Oyster Perpetual series. It was only cast in 18K gold in the past, and now it is available in precious platinum.

Platinum material shines with a charming white luster, and it isn’t easy to process, especially precision processing. Rolex has developed an innovative process for this purpose, casting a triangular pitted outer ring in 950 platinum. The exquisite pit pattern shape and shiny finish effect are the crystallization of Rolex’s outstanding professional skills, which can be called a model of technology.

The Day-Date 40 has 3255 movements with leading watchmaking technology, accurately displaying hours, minutes, seconds, days of the week, and dates. Like all Rolex watches, the Oyster Perpetual Day-Date 40 is certified by the Superlative Observatory as a chronometer, ensuring the eye performs exceptionally well when worn.

Rolex unique design

The week-date model launched in 1956 pioneered the world’s first calendar watch with a curved window at noon to display the complete writing of the week, which was a significant technical achievement of the year. The week display is available in 26 languages to choose from. The watches of the Day-Date series are only cast in precious metals such as 18K yellow gold, 18K white gold, 18K Everose gold, or 950 platinum. Knockoff designer watches.

Many dignitaries, presidents, and visionaries from all over the world have worn the day-date model. This watch is very well known, especially its iconic head-of-state strap, which shows the supreme style of the eye. The name of the belt is reminiscent of the prominent person who wears it, making the Day-Date a veritable “Führer’s Watch” like no other.

Oyster case, a symbol of water resistance

Guaranteed water-resistant to a depth of 100 meters (330 feet), the 40 mm Oyster case of the Day-Date 40 is a paragon of robustness and elegance. The middle point is cast from a solid block of 950 platinum. Rolex watchmakers use brand-specific special tools to tighten the finely pitted bottom cover to seal the case, so only Rolex watchmakers can access the movement. The double buckle lock winding crown has a dual waterproof system firmly screwed to the point. The mirror surface is made of anti-reflective sapphire crystal, which is hard to scratch. A small convex lens window at 3 o’clock makes it easy to read the date. The waterproof Oyster case of the watch gives the movement the best protection. Fake watches for sale.

Caliber 3255 Perpetual movement

The Day-Date 40 is equipped with Caliber 3255, launched in 2015 and entirely developed and manufactured by Rolex. The self-winding movement equipped with it has obtained several patents, fully embodying Rolex’s innovative and excellent watchmaking technology. It has further improved accuracy and reliability, power reserve, shock resistance, anti-magnetic and convenient use. Perfection.

The 3255 movements are equipped with Rolex’s patented Chronergy escapement system, which is efficient and reliable. This escapement is made of nickel-phosphorus and is not disturbed by magnetic fields. The movement is equipped with Rolex’s patented blue Parachrom hairspring, made of a unique paramagnetic alloy cast by Rolex. The balance spring assembly of the action is fitted with the high-performance Paraflex cushioning device designed and patented by Rolex to improve the shock resistance of the movement.

Caliber 3255 has a perpetual self-winding component wound by an eternal oscillating weight. The barrel’s structure and the escapement system’s excellent efficiency increase the power reserve of the 3255 movements to about 70 hours.

President strap

The Day-Date 40 comes on a President bracelet. The head-of-state strap with three solid links is specially designed for the famous watch model Oyster Perpetual Day-Date (Oyster Perpetual Day-Date), launched in 1956. It is only cast in 18K gold or 950 platinum—an exclusive strap for the Datejust in precious metal.

The matching President strap is equipped with a concealed crown buckle, and the belt is embedded with ceramic components, which is more flexible and durable. Hidden lugs ensure a visually seamless connection between the strap and case.

Superlative Chronometer Certification

Like all Rolex watches, the Oyster Perpetual Day-Date 40 has also received the Superlative Chronometer certification established by Rolex in 2015. In addition, the movements of these watches are also certified by the Swiss Official Chronometer Testing Center (COSC).

The watch is tested after it is assembled, and the movement is installed in the case to ensure that the eye can perform excellently in precision, power reserve, waterproofing, and automatic winding when worn. The accuracy pursued by Rolex is much higher than the standard of precision timepieces certified by the Swiss Official Observatory.
