The storyWhy this reference matters

The Cosmograph arrived in 1963, and the reference 6239 did the thing that would define the whole line: take the tachymeter scale off the dial and engrave it on the bezel. With the dial cleared, the reversed-colour registers — black on silver, or white on black — could be read at a glance. The Daytona name appeared in print in 1964, and in 1967 it settled where it still sits, just above the six o'clock register.

The chronograph turned itself inside out twice. In 1988 the 16520 went automatic on a heavily modified Zenith El Primero base dropped to 4 Hz, and grew to today's 40 mm along the way. In 2000 came the calibre 4130, Rolex through and through, with a column wheel, vertical clutch and 72 hours. Then in 2016 the 116500LN introduced the ceramic bezel and a waiting list that became famous on its own account.

The 126500LN of 2023 is the second big revision in sixty years, and it is one of those you have to look at twice. The case loses half a millimetre, the lugs straighten out and shed the asymmetry of the previous generation, the crown guards lengthen, the register rings are made finer, and the ceramic bezel is now framed by a polished steel ring, as on the 6263 of the seventies.

IdentificationHow to tell it apart

Forty millimetres, 11.9 thick, 47.6 lug to lug and 20 mm between the lugs. Against the 116500LN, look for the polished steel ring around the ceramic of the bezel: it is the detail you can see from a metre away. Everything else comes down to tenths of a millimetre, symmetrical lugs and flatter flanks, but the ring fools nobody.

On the dial, thinner register rings and slightly smaller indices, which leaves more room for the Chromalight and gives the whole thing more air. The tachymeter numbers are in platinum PVD on the black ceramic. This example, the 126500LN-0002, is the black dial with silver registers; the lacquered white dial with black registers is the other half of the reference.

The case back is solid. The calibre 4131 is only on show in the versions with a sapphire back, such as the platinum one. If somebody shows you a steel Daytona with the movement visible from behind, the conversation has ended right there.

CollectingWhat collectors check

With a Daytona, the state of the bracelet counts as much as the state of the watch. The polished centre links scratch if you look at them, and on a watch almost nobody wears daily, a marked bracelet says more about its life than any story the seller tells.

Check the edge of the ceramic bezel, where the chips start, and that the pushers screw and unscrew smoothly: they are screw-down, and a gritty feel usually means dried-out gaskets. Check too that the chronograph hand returns exactly to twelve on reset, without stopping a hair short.

Papers, card, and the rehaut serial matching the documentation. And be wary of anyone in a hurry: this is one of the most faked watches in the world, and the steel ring on the bezel — precisely because it is the detail everyone is looking for — is among the first things the good copies already reproduce.
