The Material

The Oyster Perpetual Day-Date 40 is made of platinum and gold. Platinum, rare and precious, offers fantastic physical and chemical values in addition to its radiant appearance. Although it is soft and elastic, it hardly corrodes and thus remains permanently bright and radiant. Machining the material is extremely difficult and requires perfect craftsmanship. The Rolex brand uses only 950 platinum, an alloy containing 950 thousandths of platinum, which makes it durable and stable. The 18-carat gold is produced in the company's own foundry and thus achieves the highest quality. Depending on the different additives (copper, silver, platinum or palladium) different colours are produced. Finally, the cases are available in yellow, pink or white gold, which must meet all in-house quality standards. All housings have a diameter of 40mm.

Dial and Bezel

Different dials are also available to match the different case colours. This gives the models a face and a different expression depending on the colour/characteristics. It is manufactured almost exclusively by hand in a Rolex workshop. The indices on the leaf are made of 18 carat gold to guarantee good readability and to emphasise the quality. This prevents them from tarnishing. In addition to the dial, different bezels are also available. The riffle bezel can create a sporty appearance, whereas the smooth bezel creates a more classically elegant look (e.g. reference 228239).

The Clockwork

The heart of the watch is undoubtedly the movement. With its calibre 3255, a state of the art movement and developed in Rolex's own halls, a technical masterpiece has been installed that sets new standards. Precision, high power reserve, insensitivity to magnetic fields and shock resistance are only a few aspects that have been improved and perfected. In addition, Rolex holds 14 patents protecting the self-winding mechanism.

Feature

In addition to the precision of +/- 2 seconds per day, a scratch-resistant sapphire crystal or the 100 metre water resistance, the Day-Date is available in various languages. As the first watch with a advertised weekday display, it was quickly offered in a wide variety of languages and today has a large number of world languages on offer.
