The Rolex brand is synonymous with precision, luxury, and enduring style. A key feature of many Rolex models is the date function, a seemingly simple complication that demands sophisticated engineering to ensure flawless operation. While the majority of Rolex watches exhibit a forward-moving date, understanding how the date changes, particularly focusing on the precise midnight transition, is crucial for both appreciation and troubleshooting. This article delves into the intricacies of the date change mechanism in several Rolex models, addressing potential issues and providing guidance on setting the date correctly. We will explore the date change process in various Rolex lines, including the Datejust, Oyster Perpetual, Submariner, and GMT-Master models, examining both the standard and any potential "reverse" behaviors. The term "reverse date" in this context refers to situations where the date change appears erratic or doesn't occur at the expected time (midnight).
Rolex Date Change: The Correct Procedure
Before discussing potential problems, it's vital to understand the correct procedure for setting the date on a Rolex watch. The date on a Rolex typically advances at midnight, not midday. This precise timing is a testament to the watch's intricate movement. To set the date, you should generally *not* rapidly advance the hour hand. While some older models might tolerate this, it's generally recommended to avoid it. The preferred method involves slowly turning the crown to advance the time. As you approach midnight (or 12 AM), you will observe the date change instantaneously. The key is patience and a gradual adjustment of the time; forcing the mechanism can lead to damage.
The method of adjusting the date varies slightly depending on the specific model and year of manufacture. Some models allow independent date setting via the crown, while others require adjusting the time to initiate the date change. Always consult your watch's instruction manual or a qualified watchmaker for specific instructions regarding your model. Attempting to force the date change by rapidly advancing the hands can lead to damage to the date wheel, potentially requiring costly repairs.
Rolex Change Date Correctly: Model-Specific Considerations
Understanding the date change mechanism requires considering the specific Rolex model. The following sections will examine the date change process in detail for several popular Rolex lines:
1. Rolex Watch Datejust: The Datejust is a classic Rolex model renowned for its elegant design and reliable functionality. The date change on a Datejust should be precise and instantaneous at midnight. If the date isn't changing at midnight, or if it changes at an unexpected time, it indicates a potential problem within the movement. This could be due to several factors, including a worn date wheel, a problem with the date-setting mechanism, or even a more significant internal issue requiring professional servicing.
2. Rolex Oyster Perpetual Date Change: The Oyster Perpetual, a robust and versatile timepiece, also features a date function. Similar to the Datejust, the Oyster Perpetual's date should change precisely at midnight. Any deviation from this indicates a malfunction requiring attention. The robustness of the Oyster Perpetual movement doesn't preclude the possibility of component wear or damage over time, particularly if the watch has been subjected to shock or extreme conditions.
