The Rolex Submariner, a name synonymous with diving prowess and enduring style, boasts a rich history filled with subtle yet significant changes. One such detail, often overlooked by the casual observer, is the transition in water resistance markings on the dial. For a period, Rolex Submariners displayed their water resistance in both feet (660ft) and meters (200m), a fascinating snapshot in the brand's evolution and a key identifier for vintage enthusiasts. This article delves into the history and rarity of these transitional models, focusing on references like the 5512, 5513, and 1680, exploring the reasons behind the shift from meters to feet, and providing guidance on identifying these coveted pieces.
The Early Days: Meters First
Before the dual-marking era, Rolex Submariners proudly displayed their water resistance in meters. This was a natural progression, given the growing adoption of the metric system internationally and the scientific community's preference for this system in underwater calculations. References such as the 5512 and 5513, produced from the 1950s through the 1970s, are prime examples of this early period. These watches, with their simple, rugged designs and impressive water resistance, quickly gained popularity amongst divers and collectors alike. The 5512, with its smaller, more compact case, and the 5513, its slightly larger successor, represent iconic milestones in the Submariner's lineage. These models, particularly those in excellent condition with original dials and hands, are highly sought after by collectors and represent a significant investment.
The introduction of the 1680, featuring the coveted date function, marked another significant step in the Submariner's evolution. This reference, also produced during a period showcasing the water resistance in meters, further cemented the watch's place as a leading diving instrument. The addition of the date complication didn't diminish the watch's functionality or its appeal; instead, it broadened its appeal to a wider range of wearers, beyond just professional divers. The 1680's design, with its distinct features like the cyclops lens over the date window, remains instantly recognizable and highly collectible.
The Transition: 660ft/200m – A Bilingual Approach
The appearance of the "660ft/200m" marking on the dial represents a fascinating transition period. This bilingual approach reflects Rolex's acknowledgment of the continued prevalence of the imperial system (feet) alongside the growing dominance of the metric system (meters). While the exact reasons behind this dual marking are not definitively documented, several factors likely played a role:
* Market Segmentation: Rolex, with its global reach, likely catered to different markets with varying preferences for measurement systems. The dual marking could be seen as a strategy to appeal to both the US market, which predominantly used the imperial system, and other international markets increasingly adopting the metric system.
* Gradual Transition: The dual marking may represent a gradual shift in Rolex's production and marketing strategies, reflecting a period of adjustment as the metric system gained wider acceptance. The company may have chosen a transitional phase to minimize disruption and confusion amongst its existing customer base.
* International Standards: The coexistence of both units on the dial might also reflect a period of evolving international standards and regulations related to diving equipment and the labeling of water resistance.
