The Rolex Submariner, a name synonymous with diving prowess and horological excellence, underwent a significant update in 2021. While many changes were implemented, one aspect that garnered considerable attention, and sometimes controversy, was the increase in thickness. This article will delve deep into the 2021 Submariner's thickness, exploring its implications, comparing it to previous models, and examining its place within the broader Rolex ecosystem. We'll also touch upon related topics, such as sizing charts, price guides, and the differences between various Submariner models.
The Thickness Question: A Millimeter Makes a Difference
The 2021 Rolex Submariner, in both its date and no-date variants, experienced a slight but noticeable increase in thickness compared to its predecessor. While precise measurements can vary slightly depending on the measuring method and individual watch, the consensus points to an increase of approximately 0.7mm to 1.0mm. This seemingly minor adjustment has sparked discussion among enthusiasts, with some appreciating the enhanced robustness and others lamenting the deviation from the classic, slimmer profile.
The reason for this increase in thickness is multifaceted. Rolex, known for its continuous pursuit of improvement, likely incorporated several design modifications contributing to the added bulk. These may include:
* Movement Upgrades: The Caliber 3235 (date) and Caliber 3135 (no date) movements, while largely similar to their predecessors in terms of functionality, may have incorporated subtle design changes for improved performance, reliability, and potentially, shock resistance. These internal adjustments can contribute to a slightly thicker case.
* Improved Water Resistance: Rolex consistently pushes the boundaries of water resistance in its professional watches. The increased thickness might contribute to enhanced sealing and improved water resistance capabilities, ensuring the Submariner's legendary performance at depths of 300 meters (1,000 feet).
* Case Construction: Minor adjustments to the case material, construction techniques, or the integration of the crystal could also play a role. Rolex is constantly refining its manufacturing processes, and even seemingly small changes can impact the overall dimensions.
* Enhanced Durability: A slightly thicker case might offer improved resistance against impacts and scratches, contributing to the long-term durability that Rolex watches are known for.
