The case of the Rolex Datejust 36 is made from 18k yellow gold, a material known for its rich, warm tone and durability. Rolex's 18k yellow gold is meticulously crafted to ensure both aesthetic beauty and long-lasting performance.

The Oyster case design ensures that the watch is not only beautiful but also robust, providing water resistance to 100 meters (330 feet). This makes it suitable for everyday wear, even in more active settings, while maintaining its polished appearance.

The yellow gold used by Rolex is a signature material that holds its color and shine over time, making the watch a lasting investment.

The 100-meter water resistance rating makes the Datejust 36 suitable for swimming, showering, and other activities that involve splashes or submersion in water.

However, while it’s capable of withstanding these activities, it's important to note that it’s not designed for diving. For diving or water sports at greater depths, Rolex offers models with higher water resistance, like the Submariner or Sea-Dweller.

Fluted Bezel: Like many Datejust models, this watch may come with a classic fluted bezel, which has been a signature design element for Rolex. The fluting adds texture to the case, reflecting light beautifully and elevating the overall aesthetic.

Diamond-Set Bezel: For those seeking a more extravagant appearance, the diamond-set bezel version adds a layer of luxury by setting high-quality diamonds around the perimeter of the bezel. This version enhances the watch's opulence and is perfect for those who appreciate the sparkle and radiance of diamonds.

The dial of the Datejust 36 in yellow gold with diamonds is often paired with a refined, elegant dial color such as champagne, white, or black. However, the defining feature of this model is the diamond hour markers at each hour position, which adds a glamorous touch to the watch.

The diamonds are carefully selected for their quality, brilliance, and cut, ensuring that they sparkle under any light. The Rolex crown at 12 o’clock, along with the date window at 3 o’clock (magnified by the signature Cyclops lens), completes the clean, legible, and luxurious design.

The luminous hands are also included for visibility in low-light conditions, ensuring practicality in addition to beauty.

The Datejust 36 in Yellow Gold with Diamonds is typically paired with the Oyster bracelet. This bracelet has three-piece links that provide both comfort and durability, offering a sleek, modern look.

The Oyster bracelet features an Oysterlock clasp, which is designed to securely fasten the watch while being easy to adjust.

Alternatively, it may come with the Jubilee bracelet, which is more refined, with five-piece links, and adds a more luxurious and vintage-inspired aesthetic to the watch. The Jubilee bracelet is often favored for its comfort and smooth feel on the wrist.

he Datejust 36 in Yellow Gold with Diamonds is powered by the Rolex Caliber 3235 movement, which is one of the latest and most advanced movements from Rolex.

The Caliber 3235 is an automatic movement with Superlative Chronometer certification, meaning it’s precise to within -2/+2 seconds per day, far better than the industry’s usual standards for chronometers.

With a 70-hour power reserve, this movement ensures that the watch continues running for more than two full days without needing to be worn.

The movement includes the Chronergy escapement, which enhances efficiency and reduces friction, contributing to the movement’s reliability and longevity.

In real-world conditions, many Rolex owners report that their watches perform at or better than the official -2/+2 seconds per day accuracy specification.

However, it's important to note that, as with any mechanical watch, factors such as temperature, magnetic fields, positioning, and how much the watch is worn can have a slight effect on the accuracy of the movement.
