The Rolex Milsub, a name synonymous with ruggedness, functionality, and unparalleled collectibility, represents the pinnacle of Rolex’s commitment to crafting timepieces for professionals. More than just a modified Submariner, the Milsub is a dedicated tool watch, designed in collaboration with military forces to withstand the harshest conditions imaginable. This article delves into the captivating world of the Rolex Milsub, exploring its history, variations, value, and the enduring appeal that makes it one of the most sought-after vintage Rolex models on the market.
The Rolex Milsub, short for “Military Submariner,” wasn't a single model number but rather a series of Submariners modified to meet the specific requirements of various military units, primarily the British Ministry of Defence (MoD). These modifications distinguished them significantly from their civilian counterparts, transforming a robust diver's watch into a specialized instrument for underwater warfare. The most common and well-known Milsubs are based on the Rolex Submariner 5513, but the 5517 and other variations exist, further adding to the complexity and allure of collecting these timepieces.
A Brief History of the Rolex Milsub
The story of the Rolex Milsub begins in the late 1950s, when military forces recognized the need for reliable and accurate timing devices for underwater operations. Rolex, already renowned for the durability and water resistance of its Submariner, was a natural choice. However, the standard civilian Submariner required modifications to meet the rigorous demands of military service.
The British MoD, in particular, sought a watch that could withstand extreme depths, resist magnetic fields, and offer enhanced legibility in low-light conditions. The initial experiments involved modifying existing Submariners, but the true Milsubs, produced specifically for military use, began to emerge in the late 1960s and continued through the 1970s. These watches were often issued to specialist units, including divers, combat swimmers, and underwater demolition teams.
The modifications to the standard Submariner were substantial and varied over time, leading to a range of distinct Milsub variations that continue to fascinate collectors today. These modifications were not merely cosmetic; they were critical to the watch's functionality and survival in demanding military environments.
Key Characteristics of the Rolex Milsub
Identifying a genuine Rolex Milsub requires a keen eye and a thorough understanding of the specific features that set it apart from civilian models. Here are some of the most important characteristics to look for:
* Sword Hands: Perhaps the most recognizable feature of the Milsub is its distinctive "sword hands" (also known as "gladiator hands"). These hands, significantly wider and more angular than the Mercedes hands found on civilian Submariners, provided superior legibility underwater, especially in murky conditions. The increased surface area allowed for a larger application of luminous material, enhancing visibility.
* Fixed Spring Bars: Civilian Submariners utilize spring bars that allow for easy strap changes. However, these spring bars were deemed a potential point of failure in the harsh conditions of military service. Milsubs were equipped with fixed (or permanently soldered) spring bars, significantly increasing the watch's robustness and preventing accidental detachment of the strap. This modification necessitates the use of a NATO or similar strap that can be threaded through the fixed bars.
* T-19 Superdome Crystal: Many Milsubs featured a thicker, more robust crystal known as the T-19 Superdome. This crystal offered enhanced protection against impacts and pressure at greater depths. While not exclusive to Milsubs (some civilian models also utilized the T-19), it is a common feature and adds to the overall rugged aesthetic.
* 60-Minute Bezel: While civilian Submariners typically have a graduated bezel for the first 15 minutes, Milsubs generally feature a fully graduated 60-minute bezel. This allowed divers to accurately track elapsed time for longer dives and decompression stops. The bezel insert material also varied, with some Milsubs featuring a more durable, scratch-resistant material.
* Caseback Markings: While not universally present, many Milsubs were engraved on the caseback with military issue markings. These markings typically included a broad arrow (a British military property mark), a NATO stock number, and the year of issue. However, it's crucial to note that these markings can be faked, so their presence alone doesn't guarantee authenticity. Thorough provenance and examination by a Rolex expert are essential.rolex mil
* "T" Dial: The dials of Milsubs often featured a "T" within a circle above the six o'clock marker. This indicated the use of tritium as the luminous material on the dial and hands. Tritium was used for its superior luminosity compared to earlier radium-based materials.
* Specific Case Numbers: While not a definitive indicator on its own, certain case number ranges are more commonly associated with Milsubs. These numbers, in conjunction with the other aforementioned features, can help to establish a watch's potential military provenance.
