126500LN

The Cosmograph debuted without the Daytona name, which didn’t appear on dials until 1965. Powered by the manual-wind Valjoux 72 in a 37mm case, it was a modest seller. Its exotic dial variants, later known as Paul Newman dials for their Art Deco subdial treatment, were considered slow movers at launch. Today those same dials are among the most valuable watches ever auctioned. Newman’s personal 6239 sold for $17.8 million in 2017.

Screw-down pushers arrived, adding 50m water resistance. The 6263 wore a black acrylic bezel; the 6265 used an engraved steel bezel. Both ran the Valjoux 727. The “Big Red” 6265, released in 1972 with red Daytona text, became one of the most recognized dial executions in watch history. Paul Newman dials were produced across both references and five others, totaling six refs with exotic dials before production ended in the 1980s.

The Daytona finally went automatic. Rolex used the Zenith El Primero as a base, then modified over half its components: reducing frequency from 36,000vph to 28,800vph, removing the date, and fitting a larger free-sprung balance. The case grew to 40mm, gained crown guards, and moved to sapphire crystal. Early “Floating Dial” and “Inverted Six” examples are particularly valuable today. The 16520 is the watch that made the Daytona commercially significant.

After more than a decade of development, Rolex debuted the fully in-house Caliber 4130: column-wheel, vertical clutch, 48-hour power reserve. The case stayed at 40mm but the clasp evolved through two versions. “Patrizzi” dials, white subdial rings on early examples that age to warm brown, became one of the most sought-after modern Rolex variations. The 116520 ran for 16 years and defined the Daytona as a collector-tier reference.

LN stands for Lunette Noire. The engraved steel bezel was replaced with a Cerachrom ceramic insert: scratch-resistant, fade-proof, with a sharper tachymeter scale. The white dial Panda quickly became the most in-demand watch in the world, routinely trading at two to three times retail during peak market years. Caliber 4130 carried over. The 116500LN is now discontinued, making clean full-set examples increasingly collectible.

Introduced for the Daytona’s 60th anniversary. The case drops to 11.9mm, half a millimeter thinner than the 116500LN. Lugs are more symmetrical and curve more aggressively toward the wrist. A steel ring now frames the ceramic bezel insert. Hour markers are slimmer. The new Caliber 4131 extends power reserve from 48 to 72 hours. Two dials: white with black subdials and black with silver subdials.
