Rolex Day-Date 40

Eighteen-carat yellow gold, a champagne dial and the President bracelet — the reference that has sat under more consequential cuffs than any other.

Day-Date 40 detail

The reference

Inside the Day-Date 40.

In 1956 the Day-Date did something no wristwatch had managed before: it spelled the day of the week out in full, in a window at twelve. That single idea — information stated plainly, without abbreviation — is why it has never really needed redesigning.

This is the reference 228238: forty millimetres of 18 ct yellow gold, the fluted bezel that catches a room’s light from across it, and a champagne-colour dial whose applied markers read warm rather than bright.

It runs on the calibre 3255 with roughly seventy hours of autonomy, and it is worn on the President — the semi-circular three-piece bracelet made for this watch and, ever since, named for the people who wore it. Gold, but never loud about it.

01

The day display

The weekday written out in full at twelve, the date at three — the detail that defined the reference and still separates it from everything else.

02

The bracelet

The President: semi-circular three-piece links in solid gold, with a concealed Crownclasp that leaves the line of the bracelet unbroken.

03

The movement

Calibre 3255 with the Chronergy escapement and ~70h reserve. Certified Superlative Chronometer.

It does not abbreviate the day. It never had to.
