The Rolex Submariner 1680. The name conjures images of daring underwater exploration, rugged durability, and timeless elegance. This iconic timepiece, first introduced in the late 1960s, marked a significant milestone in Rolex history – the arrival of the date function in their celebrated Submariner line. While the robust exterior and instantly recognizable design are captivating, the heart of the 1680 lies within its movement, a testament to Rolex's commitment to precision and reliability. This article will delve deep into the Rolex 1680 movement, exploring its intricacies and examining the watch's various iterations, focusing on key features that have made it a collector's dream and a legend in the horological world.
Before focusing specifically on the movement, let's establish the context surrounding the Rolex Submariner 1680. Its introduction was a significant development, adding a practical date complication to the already highly functional and rugged Submariner design. The earlier Submariners, notably the reference 5512 and 5513, were celebrated for their simplicity and reliability, but the addition of a date window addressed a common user request for increased functionality. This improvement, however, required a more complex movement, pushing the boundaries of Rolex's engineering prowess at the time.
The Calibre 1570 and its Successor, the Calibre 1575:
The heart of the Rolex Submariner 1680 beats with either the Calibre 1570 or its successor, the Calibre 1575. Both are automatic, self-winding movements, showcasing Rolex's mastery of mechanical watchmaking. The key difference between these two movements lies in the date-changing mechanism. The Calibre 1570, used in the earlier examples of the 1680, featured a quick-set date function that was slightly less refined than the later Calibre 1575. The 1575 incorporated improvements that resulted in a smoother, more reliable date-setting experience. Both movements, however, share several core characteristics that define their quality and longevity.
These movements are renowned for their robustness and accuracy. They are built to withstand the rigors of daily wear and tear, and even the harsh conditions for which the Submariner was designed. The robust construction, incorporating high-quality materials and precise manufacturing techniques, is a hallmark of Rolex. Features like the shock-resistant Incabloc system and the self-winding mechanism via a rotor ensure the watch maintains accurate timekeeping even under demanding circumstances. The movements were also meticulously finished, reflecting Rolex's dedication to both functionality and aesthetics.
