The title "Rolex Oyster Perpetual Date Quartz Quart Jaran" is slightly misleading, as "Quart Jaran" doesn't correspond to any known Rolex model or designation. However, it likely points to a misunderstanding or a misspelling referencing the Rolex Oyster Perpetual Date and Day-Date models equipped with the OysterQuartz movement. This article will therefore explore the fascinating, albeit short-lived, chapter in Rolex history: the OysterQuartz. We will delve into its development, specifications, various models, and its place within the broader context of Rolex's horological legacy.
Rolex Oyster Perpetual Date Quartz: A Five-Year Odyssey
The development of the Rolex OysterQuartz movement, specifically calibers 5035 (for Datejust models) and 5055 (for Day-Date models), represents a significant, albeit unconventional, moment in the brand's history. Known for its unwavering commitment to mechanical movements, Rolex's foray into quartz technology wasn't a knee-jerk reaction to the quartz crisis of the 1970s. Instead, it was a meticulously planned and executed project that aimed to prove Rolex could master quartz technology to the same exacting standards it applied to its mechanical movements. This commitment to quality and precision is evident in the five years Rolex dedicated to developing these movements. It wasn't simply about slapping a quartz movement into a pre-existing case; it was about integrating the technology seamlessly into the iconic Oyster case and ensuring the high levels of accuracy, reliability, and durability synonymous with the brand.
The five-year development period involved extensive research and development, ensuring the OysterQuartz met Rolex's rigorous standards. This included not only the movement itself but also the integration of the quartz technology within the Oyster case, maintaining its water resistance and overall robustness. The result was a movement that boasted exceptional accuracy and longevity, proving that Rolex could compete in the quartz market without compromising its core values.
Rolex Oyster Quartz Movements: Calibers 5035 and 5055
The heart of the OysterQuartz lies in its two main calibers: the 5035 and the 5055. While both were quartz movements, they differed slightly to accommodate the different functionalities of the Datejust and Day-Date models. The caliber 5035, powering the Datejust models, displayed the date through a cyclops lens over the date window at 3 o'clock, a signature Rolex feature. The caliber 5055, powering the Day-Date models, added the day-of-the-week complication, displayed in a window at 12 o'clock, further highlighting the prestige and complexity of these models.
Beyond their core functions, both movements shared key characteristics reflecting Rolex's dedication to quality:
* High Accuracy: The OysterQuartz movements achieved remarkable accuracy, significantly exceeding the standards of many competing quartz watches. This accuracy was a testament to Rolex's precise manufacturing processes and rigorous quality control.
* Robust Construction: The movements were designed to withstand the same rigorous testing as their mechanical counterparts. This ensured the exceptional durability and reliability expected of a Rolex watch.
* Integration with the Oyster Case: The seamless integration of the movement within the iconic Oyster case was a key aspect of the OysterQuartz’s design. The case provided the same water resistance and protection as the brand's mechanical watches.
* Long Battery Life: The OysterQuartz movements offered a significantly longer battery life compared to many contemporary quartz movements, minimizing the frequency of battery replacements.
