The allure of a Rolex Oyster Perpetual Datejust is undeniable. Its timeless design, impeccable craftsmanship, and enduring prestige have solidified its position as an icon in the world of horology. But beyond the elegant dial and the iconic fluted bezel lies another element of fascination: the back of the watch. This seemingly simple surface holds a wealth of information, a silent testament to the intricate mechanics and Swiss heritage within. Today, we delve into the specifics of a particular model, examining the features and significance of the inscription "25 Jewels Swiss Made" found on the caseback of a Rolex Oyster Perpetual Datejust, priced at $5,500.00. This price point suggests a pre-owned example, potentially a vintage piece or a more recent model depending on the specific reference number and condition.
The inscription itself, "25 Jewels Swiss Made," immediately speaks volumes about the watch's construction and origin. Let's break down each component:
25 Jewels: This refers to the number of jewels – synthetic rubies, sapphires, or other hard stones – used in the watch's movement. These jewels serve as bearings in the intricate mechanism, reducing friction and wear on delicate components. The higher the jewel count, generally, the smoother and more durable the movement is expected to be. A 25-jewel movement indicates a relatively high level of precision and sophistication, typical of a high-quality automatic movement like that found in the Rolex Oyster Perpetual Datejust. The jewels are strategically placed in areas of high friction, protecting the pivots and allowing for smoother rotation and longer lifespan. This attention to detail is a hallmark of Rolex's commitment to exceptional quality.
Swiss Made: This is more than just a geographical designation; it's a certification of quality and craftsmanship. The "Swiss Made" label is subject to strict regulations by the Swiss Federal Institute of Metrology (METAS). These regulations ensure that a significant portion of the watch's manufacturing and assembly takes place in Switzerland, meeting specific quality control standards. The use of "Swiss Made" on a Rolex watch is a guarantee of its origin and adherence to rigorous Swiss watchmaking traditions. This certification is a crucial element in the watch's value and prestige.
The Rolex Oyster Perpetual Datejust 8570F (and other relevant references): While the exact reference number isn't specified beyond the general description, the fact that it's a Rolex Oyster Perpetual Datejust allows for a more detailed examination. The 8570F is a potential reference number for a Datejust, though many others exist. Each reference number corresponds to a specific configuration of the watch, including case size, dial design, bracelet type, and movement. The $5,500 price point suggests a pre-owned watch, possibly a model from a particular era or with specific features influencing its value. The condition of the watch, any included accessories, and the current market demand heavily influence this price.
