Rolex New Oyster Perpetual Week Calendar

As a symbol of elegance and dignity, the Oyster Perpetual Day of the Week calendar type displayed at Baselworld 2012 is all precious metal styles, with a new look, highlighting the style of outstanding watch.
 The day-of-the-week model was introduced in 1956 and was the first watch to display the day of the week in a small window on the dial. It inherits all Rolex watch craftsmanship and technology, and reappears with a new dial, thus continuing to write the wonderful legend of Rolex.

Chocolate, diamonds and rubies
 This weekly calendar is made of 18 ct eternal rose gold with a unique shiny sheen. It has a chocolate-colored dial with the hour marker set with 8 diamonds and two baguette rubies at 6 and 9 o’clock.
Rolex Eternal Rose Gold
 This model’s oyster strap and case are crafted in 18 ct Everose gold by Rolex’s own foundry and sent to the workshop for processing. This pink alloy was developed by Rolex, and platinum was added to make pink gold exude an incomparable fineness and warmth. In addition, the molding, processing and polishing processes are more carefully taken care of, making the 18 ct eternal rose gold emit a unique sparkle.

Oyster Case-Excellent Waterproof Symbol
 The 36-mm day-of-the-week Oyster case guarantees water resistance to 100 meters, a perfect example of proportion and elegance. The unique middle case is cast from a solid piece of 18 ct solid gold. The bottom case is screwed tightly by Rolex’s special tools to completely seal the case. The winding crown uses a patented double-lock waterproof system and is firmly screwed on the case. Triangular pitted outer ring is a major aesthetic feature of Rolex. The mirror is made of scratch-resistant sapphire glass, and a convex magnifying calendar window is provided at 3 o’clock for easy date reading. The fully sealed day-of-the-week Oyster case gives the precision movement the best protection.
Calibre 3155-Advanced Precision Timepiece
 The day-of-the-week model is equipped with a 3155 self-winding mechanical movement entirely developed by Rolex. Like all permanent movements, the 3155 caliber has also been officially accredited with a timepiece. This certification is awarded exclusively to precision watches that have successfully passed the Swiss Precision Timepiece Testing Centre (COSC) test. The construction of this movement is the same as all oyster movements, and it is accurate and reliable. As the heart of the watch, its balance wheel uses Rolex’s patented blue PARACHROM hairspring, which is manufactured in-house with unique alloys. This hairspring is not disturbed by magnetic fields, and when temperature changes are still very stable, it is ten times more shock-resistant than traditional hairsprings.
Comfortable and elegant oyster strap
 This day-of-the-week Oyster bracelet is crafted in 18 ct Everose gold with a crown buckle. This elegant solid link bracelet was developed and patented by Rolex, which is comfortable to wear and easy to operate.
