The Rolex Submariner. The name itself conjures images of underwater exploration, rugged durability, and timeless elegance. 2021 saw the iconic dive watch undergo a significant refresh, captivating watch enthusiasts and collectors worldwide. This review delves into the nuances of the 2021 Rolex Submariner, examining its features, performance, pricing, and availability, providing a comprehensive overview for prospective buyers.
The 2021 Refreshed Design: A Subtle Evolution
While retaining the core DNA of its predecessors, the 2021 Submariner introduced subtle yet impactful design changes. The most noticeable alteration is the increase in case size from 40mm to 41mm. This seemingly minor adjustment enhances the watch's overall presence on the wrist, offering a more substantial feel without compromising its classic proportions. The slightly larger case also contributes to improved legibility, especially with the updated dial markers.
The updated dial is arguably the most significant change. While maintaining the iconic Submariner aesthetic, Rolex refined the hour markers, opting for larger, more prominent indices that boast enhanced luminescence for superior readability in low-light conditions. The hands, too, have been redesigned, showcasing a more pronounced shape for improved visibility underwater or in dimly lit environments. These subtle changes significantly improve the watch's practical functionality without sacrificing its inherent design elegance.
The crown guards, a hallmark of the Submariner's design, remain largely unchanged, providing robust protection for the Triplock winding crown. This three-fold sealing system, along with the reinforced case construction, contributes to the exceptional water resistance of the watch.
Real-World Water Resistance: Beyond the Specifications
Rolex is renowned for its rigorous testing procedures, exceeding industry standards to ensure the exceptional performance of its timepieces. While the dial indicates a water resistance of 300 meters (1000 feet), Rolex internally tests its dive watches to a significantly higher pressure. The real-world working water-resistant depth of the 2021 Submariner is estimated to be approximately 375 meters (1230 feet), representing a 25% safety margin built into Rolex's testing protocols. This commitment to exceeding specifications underscores Rolex's dedication to producing robust and reliable instruments for professional divers. The Oyster architecture, a hallmark of Rolex's engineering prowess, plays a crucial role in achieving this exceptional water resistance. The Oyster case, with its monobloc middle case, screw-down case back, and screw-down crown, forms an impenetrable barrier against water ingress.
Movement & Accuracy: The Heart of the Submariner
The 2021 Submariner models are powered by the Calibre 3235 (for the Date versions) and the Calibre 3135 (for the No-Date versions), both in-house manufactured movements known for their precision, reliability, and long power reserve. These movements boast a power reserve of approximately 70 hours, providing ample timekeeping capability even if the watch is not worn for extended periods. The Calibre 3235 incorporates the Chronergy escapement, a Rolex-patented technology made of nickel-phosphorus, enhancing the movement's resistance to shocks and magnetic fields. Both movements are certified by COSC (Contrôle Officiel Suisse des Chronomètres), guaranteeing their accuracy within specific tolerances.
