The Evolution of the Rolex Submariner Date: 1680 to 16610

Setting the Scene: Why the Date Complication Mattered

When Rolex added a date window to its professional dive watch in 1969, purists raised eyebrows. The original no-date Submariner of 1953 had focused on absolute legibility under water; adding a calendar seemed superfluous for a tool built to time decompression stops. Yet the market was changing. Professionals still bought Submariners, but an ever-growing group of enthusiasts wore them as daily companions—at desks, on aircraft and in boardrooms. A date made everyday life easier, while the signature Cyclops magnifier gave Rolex a recognisable design cue that became shorthand for modernity in the 1970s. From the first 1680 through to the pre-ceramic 16610, the Submariner Date would evolve in step with advances in materials science, movement engineering and shifting tastes, all while preserving its core identity as a robust, dependable diving instrument.

Reference 1680 (1969 – 1979): The First Submariner Date

The 1680 debuted late in 1969, retaining the 40 mm Oyster case but introducing the Calibre 1575 movement and a colour-matched date wheel beneath a Cyclops. Early examples—colloquially called “Red Subs”—carried one line of red SUBMARINER text above the depth rating, a small but potent flash of colour that would become highly collectable once the red paint was dropped around 1975. Black aluminium bezel inserts remained bidirectional, the acrylic crystal sat proud of the bezel lip, and tritium paint provided lume. Rolex rated the watch to 200 metres, mirroring the no-date 5513, yet it felt more cosmopolitan: desk divers loved knowing the date at a glance. Over the decade the dial font thickened, the minute track closed, and a new variant with white text replaced the red—changes that help modern collectors date a 1680 to within a couple of years. Despite the tweaks, the reference stayed true to its era: a tool watch whose charm lies in matte dials, domed plexi warmth and the occasional “tropical” brown fade.

Reference 16800 (1979 – 1988): The Transitional Pioneer

Launched in 1979, the 16800 straddled old and new. It ushered in the Calibre 3035 with a higher 28,800 vph beat rate and, crucially, a quick-set date, allowing owners to correct the calendar independently of the hour hand. The once-flat acrylic crystal gave way to a sapphire lens, boosting scratch resistance and enabling Rolex to raise water-resistance to 300 metres. A unidirectional bezel—borrowed from the Sea-Dweller—improved diver safety by preventing accidental extension of timing. Early 16800s kept the beloved matte tritium dials, but by 1984 glossy lacquer with white-gold surrounds signalled a move toward a more luxurious aesthetic while protecting the lume from corrosion. These transitional pieces, combining sapphire toughness with the warmth of aged tritium, are among the most characterful Submariners Date ever produced. Collectors also note the thicker case profile necessitated by the sapphire crystal, a subtle cue that the 16800 belonged to a new generation even while wearing much like its predecessor on the wrist.

Reference 168000 (1988): The Three-Zero Curiosity

Produced for only about nine months in 1988, the 168000 (spoken “triple-zero”) is less a separate chapter than a technical footnote. Rolex upgraded its steel from 316L to the more corrosion-resistant 904L alloy, already tested on Sea-Dwellers operating in saturated diving environments where chloride pitting was a constant threat. To signify the material change, the brand tacked an extra zero onto the reference number. Beyond metallurgy, the watch mirrored late-run 16800s: same Calibre 3035, same glossy dial, same sapphire crystal. Short supply has elevated the 168000 to cult status today, yet at launch most buyers barely noticed the difference—Rolex did not even mention new steel in catalogues—showing how incremental the Submariner’s evolution can be.

Reference 16610 (1988 – 2010): Perfecting the Formula

Arriving in late 1988, the 16610 carried the freshly introduced Calibre 3135. The movement’s larger balance wheel and full balance bridge added shock stability, while its revised gear train simplified servicing. Externally, the watch looked familiar: 40 mm steel case, aluminium bezel insert and sapphire crystal. Early tritium dials soon gave way to LumiNova in 1998 and Super-LumiNova in 2000, addressing fading lume performance without altering the glossy aesthetic. Bracelet evolution ran in parallel: hollow end links and folded 93150 links at first, followed by solid end links (SEL) and solid centre links in the early 2000s. Lug holes disappeared around 2003, streamlining the case flanks but frustrating strap-swappers. Through all revisions the 16610 remained the archetypal Sub Date: robust enough for saturation dives yet smart enough for a suit. By the time production ended in 2010, over two decades of continuous improvement had cemented it as a modern classic—and set the stage for the ceramic-bezel era that followed.

Design and Technical Progression in Context

From 1680 to 16610, the Submariner Date absorbed material and mechanical innovations at a measured pace. Movements stepped from the workmanlike 1575 to the high-beat quick-set 3035, then to the refined 3135 with its free-sprung balance. Water-resistance marched from 200 m to 300 m, bezel function improved, and lume chemistry advanced from tritium to photoluminescent pigments that charge by daylight. Each jump balanced tradition against function: Rolex never rushed change for its own sake. The acrylic-to-sapphire transition illustrates this philosophy. Sceptics worried a flat, shiny crystal would ruin the Sub’s tool-watch soul, yet Rolex engineered the sapphire to sit almost flush, avoiding the high-domed distortions of plexi while preserving legibility and pressure resistance. Likewise, the shift to 904L steel was driven by corrosion science rather than marketing, reflecting Rolex’s long-term focus on longevity.

Cultural Impact and Collectability

Beyond engineering, these references chart broader cultural shifts. The 1680’s red text captured the spirit of late-sixties experimentation, a pop of colour in an era of bold typography and psychedelic palettes. When the text turned white, the watch adopted the sober minimalism of the seventies energy crisis. The 16800’s sapphire crystal, glossy dial and higher beat echoed luxury’s rise in the affluent eighties, positioning the Sub Date as both statement and status symbol. The brief 168000 became a talking point for connoisseurs who relish arcane reference quirks. Finally, the 16610 accompanied the globalisation and digital convergence of the nineties and 2000s, becoming a common sight in airports, trading floors and red carpets, its silhouette instantly recognisable even to non-enthusiasts. Yet scarcity plays out differently across the range. Red-line 1680s, early matte-dial 16800s and 168000s enjoy collector premiums due to limited production or fragile dial variants; late-run 16610s, produced in the tens of thousands, reward seekers of condition rather than rarity.

Final Thoughts

From the pioneering 1680 to the long-running 16610, the Submariner Date’s pre-ceramic lineage tells a coherent story of evolutionary engineering. Rolex refined water-resistance, accuracy and durability step by step, never losing sight of the original brief: a watch reliable enough for professional divers yet versatile enough for everyday life. Whether you admire the warm charm of a plexi-crystal 1680, the transitional character of a matte-dial 16800, the metallurgical curiosity of a 168000 or the do-anything confidence of a late-era 16610, each reference reflects its period while contributing to a continuous heritage that spans more than five decades. Collectors may debate favourites, but taken together these models exemplify how incremental innovation can keep a design relevant without diluting its essence—a lesson as enduring as the stainless steel cases that house these legendary movements.
