Reference:116518

Daytona -> 116518

The 116518 is the full yellow gold Daytona on a leather strap of the in-house cal 4130 generation — the strap-and-deployant counterpart to the bracelet-mounted 116528 and the cal 4130 successor to the Zenith-era 16518. Produced from 2000 to roughly 2015, it carries the same 40mm 18k yellow gold case, the same engraved gold tachymetre bezel, and the same caliber 4130 movement that defines the rest of the in-house first-generation Daytona line. What makes it specific is the configuration: gold case on alligator with a yellow gold deployant clasp, no factory Oyster bracelet, and one of the broadest dial catalogues in the cal 4130 family.

The 116518 is also the reference most often confused with its post-2017 successor. Rolex retired the engraved-gold-bezel leather-strap Daytona around 2015 and replaced it in 2017 with the 116518LN — same case metal, but with a Cerachrom ceramic bezel and a black Oysterflex elastomer-and-titanium strap in place of leather. The two share five characters of reference number and almost nothing else mechanically beyond the cal 4130. This article covers the engraved-gold-bezel leather-strap reference only.

Where it sits in the line

The 116518 occupies the leather-strap full-gold slot in the cal 4130 launch lineup. Rolex announced five cal 4130 Daytona configurations at Baselworld 2000: the steel 116520 on Oyster, the Rolesor 116523 on Oyster, the yellow gold 116528 on Oyster, the yellow gold 116518 on leather, and the white gold 116519 on leather. The split is by case material plus bracelet-or-strap decision. The 116518 is the gold-case watch sold on alligator from the factory, with no standard Oyster bracelet option.

The predecessor is the 16518, the Zenith-based cal 4030 yellow gold Daytona on leather that ran from 1988 to 2000. The 2000 transition brought the in-house movement, the 72-hour power reserve, and the modernised dial-printing programme; the case profile, the gold engraved bezel, and the leather-strap-with-deployant configuration carried over. The successor in the Rolex catalogue is the 116518LN, which arrived in 2017 with a Cerachrom monobloc black ceramic bezel and an Oysterflex strap. The 116518 is consequently the last engraved-gold-bezel yellow gold Daytona Rolex ever delivered on a leather strap.

Production outline

The 116518 ran for roughly fifteen years across the same case-serial chronology as the rest of the cal 4130 family. Pre-2010 production used the Rolex letter-prefix system shared across the catalogue; from mid-2010 onward case serials switched to the random eight-character alphanumeric format that has no public year mapping. See Reference:Serial-numbers for the full key.

There is no separate 116518 generation timeline: the reference tracks the 116528 production chronology in parallel, with the same lume transitions (Luminova at launch, Super-Luminova within the first few years, Chromalight on later production) and the same cal 4130 stability across the run. End of production lands around 2015 in the published literature, with the discontinuation closing out the engraved-gold-bezel leather configuration ahead of the 2017 116518LN announcement. The two-year gap between the two yellow gold leather Daytonas is the cleanest break Rolex made in the modern Daytona catalogue.

The 116518 does not host the APH-error dial that defines a portion of 116520 black and white dial production around 2009 to 2010. Phillips's Logan Baker frames the APH misprint as specific to the steel reference's dial-printing batch; the 116518 catalogue does not record it.

Movement notes

Cal 4130 sits inside every 116518 — the same movement that powers the 116520, 116523, 116519, and 116528. Vertical-clutch chronograph coupling, column-wheel switching, 72-hour power reserve, 44 jewels, 28,800 vph, COSC certification, Parachrom blue hairspring on later production. Hour and minute counters share a single side of the movement, and the mainspring can be replaced without uncasing.

Cal 4130 is Rolex's first wholly in-house chronograph movement. Thirty-seven years of bought-in chronograph bases — the Valjoux 72 family from 1963, the Zenith El Primero base from 1988 — ended when the 4130 launched in 2000 across the five-configuration cal 4130 Daytona family. The 116518 is the leather-strap point of entry into that transition.

Dial map

The 116518 dial catalogue runs broader than the steel 116520's, with the gold case carrying decorative finishes the steel reference never offered. The standard configurations and the most-documented decorative variants follow.

Dial	Period	Distinguishing features
Champagne with gold markers	2000–2015	Most common 116518 layout; gold-tone sub-dial rings; applied gold five-minute markers
Black with red Daytona script	2000–2015	Black base with red "Daytona" above the 6 o'clock sub-register; applied gold markers
White "Panda" with gold markers	2000–2015	White base, three sub-dials in contrasting tone, applied gold markers
Mother-of-pearl, white	mid-to-late production	White iridescent MOP base with applied gold or Roman markers
Mother-of-pearl, black	mid-to-late production	Dark iridescent MOP base with applied gold or Roman markers
Mother-of-pearl, Tahitian	mid-to-late production	Dark Tahitian MOP base with diamond hour markers on most documented examples
MOP with diamond markers	mid-to-late production	White, black, or Tahitian MOP base with applied factory diamond hour markers
Champagne with diamond markers	mid-to-late production	Champagne base with applied factory diamond hour markers; sub-registers gold-tone
Black with diamond markers	mid-to-late production	Black base with applied factory diamond hour markers
Roman numeral indices	sub-variant	Applied gold Roman numerals at hour positions; available on MOP and standard layouts
Pavé and pavé-with-coloured-stones	late production	Factory pavé with ruby or sapphire accents — case-by-case authentication required

Karyn Orrico's "Vintage Rolex Daytona: The Gold Standard" piece (Sotheby's, 2024) catalogues white Panda and diamond-set hour-marker examples on the cal 4030 16518, and the same dial families carry forward to the 116518 with the in-house movement underneath. Forum and auction documentation of MOP-with-Roman-numeral 116518s is consistent enough across the production run to read as a regular catalogue option rather than a one-off. Pavé and gem-set layouts outside Sotheby's, Phillips, or Christie's lot text need case-by-case authentication; the late cal 4130 era saw both factory and aftermarket gem-setting on yellow gold Daytonas, and the line between them is not always documented in dealer catalogue copy.

Case, bezel, crystal, and crown

The 116518 case is 40mm in 18k yellow gold — the same nominal dimension as the steel 116520, executed in solid gold rather than steel. Lugs and case flanks carry the same profile as the cal 4130 family standard, with crown guards integrated into the case and the 700-series Triplock screw-down crown at 3 o'clock. Water resistance is 100m / 330ft, identical to the steel reference. Case thickness on documented examples runs to roughly 12.4mm, marginally thicker than the steel 116520's measured profile because of the gold-forging tolerances Rolex used through the cal 4130 run.

The bezel is engraved 18k yellow gold with the tachymetre scale. No aluminium insert, no ceramic — Cerachrom did not arrive on the yellow gold leather Daytona until the 116518LN in 2017, so every 116518 wears the engraved gold bezel through its full production. The bezel font matches the wider cal 4130 family, with the tachymetre numerals running from 60 to 400 around the ring.

The crystal is flat sapphire with no Cyclops; the running-seconds sub-dial sits at 6 o'clock. The Triplock crown handles the 100m water rating. Screw-down chronograph pushers sit on either side of the crown, the same trade-off the rest of the 116520-generation carries for the case's water resistance — they have to be unscrewed before the chronograph can be started. Pusher-screw feel and travel match the steel 116520. Case finishing on the 116518 is mixed: polished bezel and case-flank treatment with brushed lug tops, with refinishing on heavily-polished examples a routine secondary-market issue that suppresses prices on otherwise good watches.

Bracelets, end links, and clasps

The 116518 is a leather-strap reference. Every documented original-equipment example shipped on alligator leather with an 18k yellow gold deployant buckle. No factory Oyster bracelet was offered for the 116518 — that configuration is the 116528. Aftermarket gold Oyster fitments do appear on individual 116518 cases at the dealer tier, generally pulled from a 116528 or a Day-Date 18238 and refitted to the 20mm 116518 lug spacing. These reconfigurations are not original delivery and trade as such on the secondary market.

The deployant buckle is 18k yellow gold throughout the run, in the standard Rolex deployant geometry of the period. Strap material was always alligator from Rolex, with black, brown, and burgundy as standard colours and other tones available through the catalogue. Strap is a wear item; owners typically replaced it multiple times across the watch's life, and a surviving 116518 with its original Rolex-stamped strap and the original deployant in untampered condition is the period-correct configuration. A later aftermarket strap with the original deployant is the more common surviving form, and a fully refurbished strap-and-deployant set with no original Rolex components is normal at the dealer tier.

Rubber-strap aftermarket fitments — Rubber-B and similar third-party sets — are common on owned-and-worn 116518s and do not affect originality on the watch head, only on the wearable kit. Some auction lots note the rubber alongside the original Rolex deployant; others present only the rubber.

Special branches

Tiffany & Co. and other double-signed dials

Tiffany-signed 116518s appear sporadically at major auction houses, following the broader Tiffany-signed Rolex tradition of the period. The signature is applied on the dial below the 6 o'clock Cosmograph block, on the standard champagne or black layouts. Cartier-signed and Vacheron-signed examples on the cal 4130 yellow gold Daytona references are thinner on the ground than in the Zenith-era 16518 catalogue — by the 2000s, the double-signed Rolex phenomenon had narrowed considerably as retailer dial programmes ended at most of the historical partners. No 116518-specific double-signed lot anchors a market-grade record in the published literature comparable to Phillips's Van Cleef & Arpels "Le Roi Soleil" 16518 (Daytona Ultimatum, Geneva, 12 May 2018, Lot 18).

Beach dial sub-branches

The pastel mother-of-pearl "beach dial" family that runs on the cal 4030 16518 — pink MOP, salmon MOP, pale blue MOP — is documented as carrying forward into early 116518 production in some dealer and auction catalogue copy, though the cal 4130 layouts read as a narrower set than the Zenith-era variants. Per-dial production volume on the 116518 beach-dial sub-branch is not documented in the major-house literature, and individual examples need to be authenticated against period documentation rather than against a single canonical layout.

Diamond, pavé, and gem-set layouts

Diamond hour markers are the most widespread decorative layer on the 116518. Sotheby's "Gold Standard" piece (Orrico, 2024) catalogues diamond-set hour-marker yellow gold Daytonas across the cal 4030 and cal 4130 references, and the configuration runs as a regular cataloguing option on champagne, black, and MOP base dials. Pavé and pavé-with-coloured-stones (ruby, sapphire) variants exist on top of that base, generally on later production where the gem-set programme was running at higher volume. Documentation of which exact pavé layouts shipped from Rolex versus which were aftermarket gem-setting is uneven across the published literature; treat any pavé 116518 outside Sotheby's, Phillips, or Christie's lot documentation as needing case-by-case authentication.

Auction record

The 116518 has not produced a single headline lot in the way the 16518 produced the Phillips "Le Roi Soleil" Van Cleef & Arpels signed lot in 2018. Auction interest in the cal 4130 generation has concentrated on the steel 116520 (Patrizzi-eligible Zenith-era refs are the prior generation) and on the rarer dial variants of the gold cases. Standard champagne 116518s have anchored the floor of the cal 4130 yellow gold leather market through the 2010s and into the 2020s, with diamond-marker, MOP, and Tahitian MOP variants pulling the premium end. Public auction records on standard 116518 examples are thinner than on the steel 116520 because the gold leather configuration trades more often in the dealer market than at the major houses.

The 2017 introduction of the 116518LN and its rapid market acceleration through the late 2010s — the Cerachrom yellow gold Daytona on Oysterflex caught the same allocation-economy dynamics as the steel 116500LN — has dragged the 116518 along behind it. Used prices on the engraved-bezel reference firmed in the years after its discontinuation, with full-set examples carrying matching box, papers, and original Rolex strap commanding a clear premium over partial-set examples. The 116518 trades on material and configuration terms rather than on headline provenance, with the rarer dial variants (MOP, sodalite where documented, factory diamond markers, factory pavé with confirmed provenance) carrying the auction-grade price band.
