September 1st, 2020, marked a significant day in the history of Rolex, particularly for enthusiasts of the iconic Submariner. This date saw the unveiling of a comprehensively redesigned Submariner collection, a watershed moment that sent ripples through the watch collecting world. While the aesthetic updates were immediately apparent – subtle yet impactful changes to the case, bezel, and dial – the most profound shift lay beneath the surface: the introduction of a new caliber movement. This article will delve deep into the significance of the September 1st, 2020, Rolex Submariner launch, exploring the key changes, their impact, and the lasting legacy of these models.
The Movement: The Heart of the Matter
Although everything about the new Submariner was, in fact, new, arguably the most substantive change was the movement. The new models were the first Submariners to feature the current-generation Calibre 3235 (in the standard Submariner) and Calibre 3230 (in the Submariner Date). These movements represented a significant leap forward in Rolex's horological prowess, building upon the already impressive legacy of their predecessors. The introduction of these calibers wasn't merely a simple upgrade; it signified a commitment to enhanced performance, precision, and longevity.
The Calibre 3235 and 3230 are both part of Rolex's family of movements featuring the Chronergy escapement. This escapement, made of nickel-phosphorus, is patented by Rolex and is significantly more resistant to shocks and magnetic fields compared to traditional silicon escapements. This enhanced robustness translates to greater reliability and accuracy in everyday wear, a crucial factor for a professional dive watch like the Submariner.
Beyond the Chronergy escapement, these movements boast a longer power reserve than their predecessors. The increased power reserve, extending to approximately 70 hours, provides greater convenience for the wearer, eliminating the need for frequent winding. This is a significant improvement for a watch that might be used in situations where winding access is limited or inconvenient. The extended power reserve also allows for easier time-setting adjustments without the worry of the watch stopping mid-adjustment.
Furthermore, the Calibre 3235 and 3230 incorporate a Paraflex shock absorber system, further enhancing their resilience against accidental impacts. This system, combined with the Chronergy escapement, ensures that the watch remains accurate and functional even under challenging conditions. The enhanced anti-magnetic properties also contribute to greater reliability in an increasingly electromagnetically charged environment.
The meticulous attention to detail evident in these movements is a testament to Rolex's unwavering commitment to quality and precision. The improved efficiency and power reserve translate to a more consistent and reliable timekeeping performance, a critical aspect for a watch that is often relied upon in demanding situations. The introduction of these calibers solidified Rolex's position at the forefront of watchmaking technology.
Aesthetic Refinements: Subtle Yet Significant
While the movement upgrades were the most significant change, the aesthetic refinements implemented in the 2020 Submariners were equally impactful. These were not radical departures from the classic Submariner design, but rather thoughtful evolutions that enhanced both the functionality and the aesthetic appeal of the timepiece.
