Rolex Datejust 116200BKSJ 36MM Black Dial Silver-tone Case

The Rolex Datejust 116200BKSJ 36MM Black Dial Silver-tone Case (Reference 116200BKSJ) stands as a defining reference within the legendary Rolex Datejust lineage—the watch that pioneered the instantaneous date window at 3 o’clock in 1945. Beautifully proportioned with a 36 mm (1.42 inches) case and a slender 11.7 mm (0.46 inches) thickness, this timepiece delivers the quintessential blend of prestige and daily versatility. Designed as an all-occasion horological staple, it slips seamlessly beneath tailored shirt cuffs while making an unmistakable statement of refined taste in professional boardrooms, evening galas, and weekend social engagements.

At the heart of the exterior construction is high-grade Oystersteel (Polished & Brushed 316L Stainless Steel), carefully sculpted with polished case flanks and brushed lug tops that contour organically to the wearer’s wrist. Framing the face of the watch is a signature Smooth Polished Domed Bezel crafted in Mirror-Polished 316L Stainless Steel. The precise geometric facets of the bezel reflect ambient lighting from every angle, producing the radiant sparkle that has made the Datejust immediately recognizable across generations. A screw-down Twinlock winding crown ensures solid structural integrity against everyday dust, humidity, and atmospheric moisture.

Protected by a scratch-resistant synthetic sapphire crystal is an immaculate Deep Lacquer Black dial configured with High-Contrast Applied Luminous Indices and Faceted Hands. At the 3 o’clock position, the world-famous Cyclops magnification lens enlarges the numerical date display by 2.5 times for instantaneous, effortless legibility at a glance. The harmonious symmetry of the dial layout balances heritage horology with crisp contemporary execution, ensuring that time and date remain clearly readable whether under direct daylight or intimate low-light evening dinner settings.

Beating reliably within the case is a precision Self-Winding Mechanical Automatic Movement (Calibre 3235 Automatic Clone) operating at a high-beat frequency of 28,800 vibrations per hour (4 Hz). This self-winding mechanical engine produces a continuous, fluid sweeping motion of the central seconds hand rather than the abrupt ticking of quartz alternatives. Equipped with a bidirectional Perpetual winding rotor, the movement continuously harnesses natural wrist motion to maintain an optimal 48 Hours Mechanical Power Reserve. It features a rapid-setting quickset date mechanism and a stop-seconds hacking function for second-exact synchronization.

Mounted to the watch is a meticulously articulated 316L Stainless Steel Oyster 3-Piece Flat Link Bracelet, designed for supple, all-day ergonomic comfort on the wrist. Each link segment is hand-inspected for smooth articulation, preventing pinching or hair pulling. The bracelet terminates in a precision-engineered Folding Oysterclasp with Easylink 5mm Comfort Extension, providing dependable security during active movement. For collectors seeking bolder wrist presence, the alternative Datejust 41 collection presents an enlarged case diameter, while this 36mm edition preserves the iconic dimensions first introduced in 1945.

To preserve the showroom brilliance of your timepiece, gently wipe the case and bracelet with a dry, lint-free microfiber cloth after wear. Always verify that the winding crown is screwed down firmly flush against the case before washing hands or entering wet environments. Note that while this timepiece offers dependable daily splash resistance (30m / 3 ATM), swimming, hot showers, and saunas should be avoided to safeguard internal rubber gaskets. Every purchase is backed by express insured courier transit with adult signature confirmation and our comprehensive 24-month mechanical warranty covering movement functionality.
