If the Rolex Submariner in stainless steel is the archetype — the reference against which all dive watches measure themselves — then the two-tone Submariner in Rolesor occupies a different but equally well-defined cultural position. The reference 116613LN, presenting the Submariner Date's architecture in the combination of Oystersteel and 18-karat yellow gold with a black Cerachrom bezel insert and black dial, is one of the most immediately recognizable watch configurations in the world. It is a watch that carries half a century of accumulated cultural meaning — worn by professionals and collectors, by those who discovered it through the water and those who discovered it through the wrist — and yet it retains, in every configuration, the functional integrity that gave it that meaning in the first place. The Rolesor Submariner is not the steel Submariner with gold added as decoration; it is a distinct expression of the same instrument, one whose material combination speaks to a tradition of luxury sports horology that Rolex essentially invented and has spent decades refining.
The Submariner's origins trace to 1953, when Rolex introduced what was then the world's first purpose-built diver's wristwatch, rated to 100 meters of water resistance. In the seven decades since, the model has been progressively engineered — water resistance increased first to 200 meters, then to the current 300 meters; the case evolved from the early reference 6204's more slender proportions to the robust 40-millimeter form that has characterized the model since the 1980s; the bezel insert migrated from aluminum to the current-generation Cerachrom ceramic with the introduction of the reference 116610 in 2010. The 116613LN is a product of that 2010 generation, the designation "LN" indicating the black Cerachrom insert — "LN" for lunette noire — distinguishing it from the 116613LB, whose blue insert and dial constitute the alternative within the two-tone Submariner family. Within the 116613LN, the black-on-yellow-gold combination creates a more dramatic visual contrast than the blue-on-yellow-gold variant, the absolute depth of the black ceramic and black dial set against the warmth of the gold producing a tension that reads as simultaneously sporty and opulent.
The case measures 40 millimeters in diameter, a dimension that Rolex maintained for the Submariner across decades of production before expanding to 41 millimeters with the introduction of the reference 126613 in 2020. The 116613LN thus represents the final generation of 40-millimeter two-tone Submariner, a distinction that has given it a specific resonance among collectors who consider the proportions of the 40-millimeter Submariner to be the model's most natural expression. The Oyster case construction — a one-piece middle case machined from solid material, with the movement loaded from the back via a screw-down caseback and the crown sealed by the Triplock triple waterproofness system — provides water resistance to 300 meters, the standard to which Rolex has held the Submariner for decades and which remains the benchmark for professional dive watch specification. In Rolesor configuration, the case middle and flanks are Oystersteel — Rolex's proprietary 904L stainless steel alloy, chosen for its exceptional corrosion resistance and its capacity to hold a mirror polish — while the bezel surround, the crown, and the bracelet center links are 18-karat yellow gold. The brushed steel case flanks and polished gold bezel surround engage in the finishing conversation that defines Rolesor aesthetics, the two materials' distinct light behaviors creating a visual interplay that shifts as the wrist moves. The Cerachrom bezel insert — the ceramic outer ring that carries the dive timing scale — is produced in black, its matte surface absorbing light in the manner specific to ceramic, its scratch resistance ensuring that this most tactilely active component of the watch's exterior will retain its appearance regardless of the practical use to which the watch is put. The graduated 60-minute scale is molded directly into the ceramic rather than applied or printed, rendered in yellow gold PVD fill that maintains its precise legibility while harmonizing with the case's gold elements. The inverted triangle at twelve o'clock, set with a single luminescent pip, provides the reference marker for elapsed time measurement, its form one of the Submariner's most enduring graphic signatures.
The dial is executed in black, specifically the deep, matte lacquer black that Rolex has refined for the Submariner across its production history, a surface that provides maximum contrast for the luminescent markers and hands that constitute the watch's primary legibility system. Applied hour markers — circular dots at the standard positions, rectangular bars at three, six, and nine, a larger rectangular bar at twelve — are filled with Chromalight, Rolex's proprietary blue-emitting luminescent compound that provides extended duration luminescence and a distinctive blue glow that distinguishes it from the green-emitting materials used by many competitors. The hands, also luminescent-filled, include the characteristic Submariner Mercedes hand at the hours position — the three-pointed hand form that provides immediate large-scale legibility underwater and in low light — and the lollipop seconds hand with its circular red tip that allows precise time synchronization. The date aperture at three o'clock, covered by the magnifying cyclops lens integrated into the sapphire crystal, presents the date with the 2.5x magnification that Rolex has associated with this function across its production. The white date disc provides legible contrast against the surrounding black dial, and the Submariner and depth rating text — "1000ft • 300m" — appears in the lower dial register as a functional specification and a visual affirmation of the watch's genuine professional credentials.
The movement is Rolex's Calibre 3135, the self-winding manufacture movement that has powered the Submariner Date across decades of production and which, in its longevity and consistency, has become the default reference point for what a serious automatic movement should deliver. The 3135 beats at 28,800 vibrations per hour and provides approximately 48 hours of power reserve from its bidirectional Perpetual rotor. Among the calibre's technical distinctions is its variable-inertia balance wheel, where timing regulation is achieved by repositioning gold Microstella nuts around the balance wheel's perimeter rather than through a conventional regulator index — a more stable and more precise approach that delivers the movement's characteristic resistance to positional variation. The Parachrom hairspring, produced from a proprietary paramagnetic niobium-zirconium alloy, provides resistance to magnetic fields up to ten times greater than conventional steel springs, while the Paraflex shock absorbers protect the movement's geometry against the physical impacts inherent in the life of a tool watch. The movement holds Rolex's Superlative Chronometer certification, confirming precision to within plus or minus two seconds per day — a standard that exceeds COSC requirements and which Rolex maintains through its own independent testing after assembly.
The Oyster bracelet in Rolesor — Oystersteel outer links and clasp body, 18-karat yellow gold center links — integrates the case and bracelet into the unified visual statement that defines the Submariner's presence. The brushed steel outer links and polished yellow gold center links maintain the Rolesor material dialogue established at the case, the combination tracking the watch's dual identity as both a functional sports instrument and a material luxury object. The Oysterlock folding clasp incorporates the Rolex Glidelock extension system — a mechanism that allows the bracelet length to be adjusted by up to 20 millimeters in 2-millimeter increments, without tools, by sliding the clasp element along a rack — a practical provision that accommodates the thickness variation between bare wrist and wetsuit sleeve, and which distinguishes the Submariner bracelet from configurations that require a watchmaker or sizing pin to adjust.
Among collectors, the 116613LN occupies the specific territory of the two-tone Submariner as a category — a watch that has been equally at home in every decade since its introduction, whose cultural moment seems perpetually present, and which has proven resistant to the cycles of fashion that periodically render other configurations temporarily out of step. The black dial and black ceramic bezel combination within the Rolesor format is the more assertive of the two 116613 variants, its darkness against the yellow gold carrying a drama that the blue alternative moderates. It is, in the most direct sense, a watch that knows exactly what it is — and has known for a very long time.
