The Rolex Explorer II, specifically the reference 1655, holds a unique position in the pantheon of Rolex sports watches. Its rugged design, coupled with its groundbreaking 24-hour bezel, solidified its place as a tool watch for serious adventurers and explorers. But beyond its iconic status, the 1655's engineering marvels, particularly its Triplock crown system, deserve a closer examination. This article will delve into the intricacies of the Rolex Explorer II 1655, focusing on its Triplock crown, its historical context, and its enduring appeal within the broader world of Rolex Explorer watches.
The 1655, with its 39mm case, represents a compelling chapter in Rolex's history. While subsequent Explorer II models have seen variations in size and features, the 1655 remains a highly sought-after collector's piece. Its most distinguishing characteristic, setting it apart from its predecessors and contemporaries, is the fixed, steel 24-hour bezel. This wasn't merely an aesthetic choice; it served a crucial purpose for navigating in low-light conditions or during extended periods of darkness. The orange hand, pointing to the 24-hour bezel, allowed for easy distinction between AM and PM, a vital feature for cave explorers, mountaineers, and others operating in challenging environments. This functionality, coupled with the watch's inherent robustness, fundamentally differentiated the 1655 from other Rolex models, establishing it as a specialized tool watch rather than a general-purpose luxury timepiece.
The Rolex Triplock Crown: A Symphony of Engineering
Understanding the Rolex Explorer II 1655 requires understanding its crown. Unlike the simpler Twinlock crown found in some other Rolex models, the 1655 boasts the superior Triplock crown system. This system, a testament to Rolex's commitment to water resistance and reliability, significantly enhances the watch's performance under pressure. The Twinlock crown, with its two sealing gaskets, provides a decent level of water resistance. However, the Triplock crown takes it a step further, incorporating three sealing gaskets for even greater protection against water ingress. This triple-gasket system effectively creates a near-impenetrable barrier, enhancing the watch's water resistance to impressive depths.
The Triplock crown's design is not just about the number of gaskets; it's about the meticulous engineering and precision manufacturing that go into its creation. The tightly fitted gaskets, combined with the crown's screw-down mechanism, ensure a secure seal even under extreme pressure. The screw-down action itself is a tactile experience, a reassuring click signaling the secure locking of the crown, a testament to the watch's robust construction.
Comparing the Rolex Twinlock vs. Triplock systems highlights the advancements in Rolex's crown technology. The Twinlock system, while effective, is a simpler design. The Triplock system represents a significant leap forward, providing superior water resistance and protection for the watch's movement. This difference is particularly crucial in a watch designed for extreme conditions like the Explorer II. The added layer of protection provided by the Triplock crown translates directly to increased reliability and durability in challenging environments.
