# Rolex Datejust II: The Complete Guide to Rolex's Modern Classic Watch
When Rolex introduced the Datejust II in 2009, the Swiss watchmaker faced a delicate challenge: how to evolve one of the world's most beloved watch designs without alienating its devoted following. The answer was a masterclass in refinement. The Rolex Datejust II collection represents a careful balance between honoring the original's legacy and embracing contemporary watchmaking standards.
A Brief History of the Datejust II
The original Datejust, launched in 1945, holds the distinction of being the first wristwatch with an automatically changing date window—a revolutionary feature at the time. For decades, it remained relatively unchanged, a testament to its timeless design philosophy. However, by the early 2000s, the watch world had evolved. Cases had grown larger, movements had advanced, and collectors demanded more presence on the wrist.
The Datejust II was Rolex's response to this shift. Introduced in 2009 with a substantial 41-millimeter case diameter (up from the classic 36mm), the Datejust II represented a natural progression for a new generation of wearers while maintaining the elegant proportions and iconic aesthetic that made the Datejust legendary.
The collection remained in production until 2017, making it a distinctly defined chapter in Rolex's history. During its eight-year run, it became a favorite among collectors seeking a larger-cased Datejust without venturing into the more specialized territory of Rolex's sport watches.
Key Design Features That Define the Datejust II
At first glance, the Datejust II appears to be a simple enlargement of its predecessor. Look closer, and you'll discover Rolex's meticulous attention to detail.
Case and Proportions
The 41-millimeter Oyster case sits at the sweet spot between wearability and presence. Unlike some oversized watches that can feel clumsy, the Datejust II maintains elegant proportions with its relatively thin case profile and balanced lugs. The case is crafted from either stainless steel or white gold, with select references combining both metals in what Rolex calls an "Everose" (their proprietary rose gold) or standard two-tone configuration.
The fluted bezel—a signature Datejust design element—appears on many variants and serves both aesthetic and functional purposes. The vertical fluting not only catches light beautifully but also provides a subtle grip for wearers adjusting the watch.
Dial Options and Aesthetics
The Datejust II's dial vocabulary is rich and varied. Rolex offered the collection in countless configurations, from classic sunburst finishes in black, blue, and silver to more adventurous colors like champagne and slate. The applied indices and Mercedes-style hands remain true to Datejust tradition, ensuring instant recognition.
The date window occupies its traditional position at three o'clock, framed by a Cyclops lens that magnifies the date by 2.5 times—standard for modern Rolex watches since 1959.
Notable References and Variants
With 16 total references catalogued in the Datejust II collection, there's considerable variety to explore.
The Stainless Steel Foundation
The Ref. 116300-0001 Datejust II Black represents the collection's most accessible entry point. Housed in stainless steel with a classic black dial, this reference exemplifies the Datejust II's versatility. It's equally at home in a boardroom or at a weekend gathering, a hallmark of the Datejust DNA.
White Gold Elegance
For those seeking more precious material, the Ref. 116334-0001 Datejust II Fluted Rhodium elevates the collection into luxury territory. Crafted in white gold with a fluted bezel and rhodium dial (a silvery, highly reflective finish), this reference exudes understated sophistication. The rhodium dial, with its subtle pattern, catches light differently than standard silver, adding visual interest and depth.
Color Variations
The Ref. 116334-0005 Datejust II Fluted Blue demonstrates Rolex's willingness to explore color within the Datejust II framework. The blue dial, paired with the white gold fluted bezel, creates a compelling contrast that appeals to collectors seeking personality without sacrificing sophistication.
Technical Specifications and Movement
Where the Datejust II truly distinguished itself was beneath the dial.
The Caliber 3136 Movement
All Datejust II references are powered by the Rolex caliber 3136, an automatic movement that represents Rolex's commitment to precision and reliability. This workhorse displays hours, minutes, and seconds, with an instantaneous date change mechanism that Rolex continuously refined over decades.
The movement is COSC-certified as a chronometer, meaning it meets stringent accuracy standards—typically keeping time within -4 to +6 seconds per day. For a watch in this category, such precision is table stakes, but Rolex's execution is flawless.
Case Construction and Water Resistance
The Oyster case features Rolex's proprietary Oysterlock bracelet system and a screw-down case back that contributes to the watch's water resistance of 100 meters (330 feet). This depth rating makes the Datejust II suitable for swimming and snorkeling, though it's not designed for diving.
The case construction employs Rolex's signature Twinlock crown, which incorporates a double waterproof system to protect the movement from moisture and dust.
Who Should Collect the Datejust II?
The Datejust II appeals to a broad spectrum of collectors, each for different reasons.
The Heritage Enthusiast
If you appreciate Rolex's history and the Datejust's iconic status, the Datejust II represents the modern evolution of a watch that's been in continuous production since 1945. It's a way to own a piece of watchmaking heritage while enjoying contemporary improvements.
The Size Seeker
For collectors who found the original 36mm Datejust too modest in proportion, the Datejust II's 41-millimeter case provides the presence they sought without compromising the design's essential character.
The Versatility Champion
The Datejust II excels as a "one watch" solution. It's formal enough for black-tie events, robust enough for daily wear, and refined enough never to look out of place. The variety of references—from stainless steel to precious metals, with numerous dial options—ensures there's a Datejust II for nearly every aesthetic preference.
The Legacy of the Datejust II
While production ended in 2017, the Datejust II's influence endures. It paved the way for subsequent Datejust models and demonstrated that Rolex could successfully modernize its most iconic designs. Collectors today recognize the Datejust II as a distinctly important moment in the watch's evolution—neither the vintage classic nor the contemporary iteration, but a thoughtful bridge between them.
The Rolex Datejust II collection remains a testament to Rolex's design philosophy: incremental refinement, unwavering quality standards, and an almost obsessive attention to proportion and balance. For those seeking a refined, capable watch with one of horological history's strongest names, the Datejust II deserves serious consideration.
