The Rolex Datejust 31, reference 78240, represents a compelling entry point into the world of luxury timepieces. At a price point often found around $6,750.00 (though prices can vary depending on condition and market fluctuations), this model offers a compelling blend of classic design, enduring quality, and inherent value. This article will explore the Rolex 78240, specifically examining its place within the Rolex Datejust family, its key features, the variations available (including the highly sought-after diamond and mother-of-pearl models), and ultimately, its value proposition in the pre-owned luxury watch market.
Understanding the Rolex 78240: A Datejust 31 Icon
The reference 78240 designates a specific iteration of the Rolex Datejust 31. The "Datejust" moniker signifies its inclusion of the instantly recognizable date window at 3 o'clock, a feature that has defined this model since its introduction in 1945. The "31" refers to the diameter of the case, measured in millimeters – a size that strikes a perfect balance between elegance and wearability, making it suitable for a wide range of wrists and occasions.
This particular reference, the 78240, usually features a classic oyster case, known for its robustness and water resistance. The oyster case, a hallmark of Rolex, is constructed from high-quality stainless steel, offering exceptional durability and protection for the movement within. The case is typically paired with a fluted bezel, adding a touch of sophistication and texture to the overall design. The fluted bezel is not merely an aesthetic choice; its intricate grooves provide a secure grip when adjusting the time.
The dial of the 78240 is where significant variations can be found. While some examples feature simple, elegant dials with baton or Roman numeral hour markers, others boast more elaborate designs. This leads us into the realm of the Rolex diamond mop 31mm and other variations discussed later in this article.
The Rolex Datejust 78240 Movement: Precision and Reliability
Powering the Rolex 78240 is a self-winding mechanical movement, typically a caliber 2135. This movement is renowned for its precision, reliability, and robustness. Rolex movements are meticulously crafted, employing advanced manufacturing techniques and rigorous quality control measures. The 2135 movement boasts a power reserve of approximately 48 hours, meaning the watch will continue to run accurately even if it's not worn for a short period. The automatic winding mechanism ensures that the watch is constantly powered by the natural movement of the wearer's wrist, eliminating the need for manual winding.
The accuracy of the 2135 movement is a testament to Rolex's commitment to horological excellence. These movements are rigorously tested to ensure they meet the brand's exacting standards for precision and reliability. This attention to detail is a significant factor contributing to the enduring value of Rolex watches, including the 78240.
