	One documented outlier is Sotheby's 2025 'Citrus' 116520, a circa 2003 watch catalogued with a factory white dial that had aged to an even citrus tone. That example should sit as an auction lead, not a rule: it shows that non-tritium 116520 dials can still develop visible colour change, but it does not prove a broad tropical sub-series for the reference.

	The 72-hour reserve is the practical payoff of cal 4130, the upgrade an owner actually feels. It is also why the 116520 became the first Daytona that could come off the wrist on Friday and run through Monday morning.		The 72-hour reserve is the practical payoff of cal 4130, the upgrade an owner actually feels. It is also why the 116520 became the first Daytona that could come off the wrist on Friday and run through Monday morning.

			The 4130 is leaner than its reputation suggests. Caliber Corner lists it at 201 components, 44 jewels, a ball-bearing rotor with seven ceramic balls, bidirectional winding, a Parachrom Blue hairspring, and a 3-6-9 layout with running seconds at six. That last point matters because the Zenith-era 4030 placed running seconds at nine; the 4130 moved the live seconds to six and the 12-hour chronograph counter to nine, giving the modern Daytona dial architecture its current map.

	For the full caliber lineage see [[Reference:Movements#cal-4130]].		For the full caliber lineage see [[Reference:Movements#cal-4130]].

			Later 4130s also carry a small but useful anti-backlash refinement inside the chronograph train. Richard Lee's SJX teardown notes that Rolex used a UV-LIGA chronograph seconds wheel with sprung, skeletonised teeth; the teeth take up play in the indirect chronograph seconds drive, reducing hand stutter without the drag and wear of a traditional tensioner spring. It is not a dial-side collectible marker, but it helps explain why the 4130 stayed in service for so long with quiet running changes rather than a public caliber replacement.

	The APH (Applied Printed Hour) error dial is the headline anomaly of the reference. Baker at Phillips frames it as an Asia-Pacific Hong Kong dial-printing error that slipped past quality control on a portion of 2009-and-later production and was never officially corrected. The market treats the misprint as a desirability feature, and APH examples trade at a small premium over standard dials. A 2018 Sotheby's lot of a white APH 116520 with chromalight blue lume sits as the publicly visible auction record for the variant.

			The gap in COSMOGRAPH is the easy tell, but Phillips notes two companion tells on many late APH dials: the O in OYSTER looks more like a zero, and the spacing across OYSTER PERPETUAL is wider than on earlier standard dials. Those details matter when checking loose claims, because APH is not just a nickname for any late 116520 dial with blue lume.

	Double-signed Tiffany & Co. dials on the 116520 turn up in the catalogues of the major auction houses. The pattern is part of the broader Tiffany-signed Rolex tradition; the earlier 16520 generation produced more documented examples.

	The 2016 ceramic-bezel transition reset the market. With the 116500LN absorbing Daytona demand at retail and the 116520 instantly the last steel-bezel Daytona, used prices climbed in the years that followed. Auction treatment has stayed selective rather than headline-driven. The steel 116520 trades regularly at Sotheby's, Christie's, and Phillips, with APH variants and original-papers examples drawing the strongest bids.
