The Rolex Submariner, a legendary dive watch synonymous with rugged elegance and precision, comes in several variations, each demanding a slightly different approach to date adjustment (if it even has a date function). This comprehensive guide will walk you through the process of changing the date on your Rolex Submariner, addressing the nuances between the different models and clarifying common misconceptions.
Before we delve into the specifics, it’s crucial to understand the two primary categories of modern Rolex Submariners relevant to date adjustment:
1. Rolex Submariner No-Date: As the name suggests, this model lacks a date window. There's no date to change! This minimalist design emphasizes the watch's core functionality: telling time accurately under pressure. If you own a Submariner No-Date, you can skip the rest of this article – there's no date-changing mechanism to manipulate.
2. Rolex Submariner Date: This version incorporates a date window at the 3 o'clock position, requiring a specific procedure to adjust the date. This is the model we will focus on in the subsequent sections. Note that even within the "Date" category, there are variations in case material (stainless steel, gold, combinations thereof), bezel materials (ceramic, aluminum), and potentially other aesthetic details – but the date-setting mechanism remains fundamentally the same.
Understanding the Rolex Submariner Date's Movement:
The Rolex Submariner Date, like most Rolex watches, utilizes a self-winding mechanical movement. This means the watch automatically winds itself through the movement of your wrist, eliminating the need for manual winding (although manual winding is possible and even beneficial for maintaining optimal power reserve). The self-winding mechanism (also known as an automatic movement or Rolex Submariner self-winding) is crucial to understanding how the date changes. The movement's power reserve, typically around 48 hours, provides energy for the timekeeping and date functions. Referencing a Rolex Submariner manual PDF (which should have accompanied your watch or can be downloaded from the Rolex website) will provide detailed diagrams and explanations.
The Date-Setting Procedure:
The date on a Rolex Submariner Date is adjusted via the crown, the knurled knob located at the 3 o'clock position. This crown is not simply for setting the time; it also controls the date function. Here's a step-by-step guide:
1. Unscrew the Crown: The crown on a Rolex Submariner is screw-down, designed for water resistance. Gently unscrew the crown counter-clockwise until it pops out. This typically requires a small amount of force but should not feel overly stiff or difficult. If you encounter excessive resistance, consult a professional watchmaker.
2. Pull the Crown to the First Position: Once unscrewed, carefully pull the crown out to the first position (approximately one click). This position typically allows you to adjust the time. However, this step is important for preparing the date mechanism for adjustment.
3. Pull the Crown to the Second Position: Now, pull the crown out further to the second position (a second click). This is the crucial step that activates the date-setting function.
