At its launch in 1956, the Day-Date was a major innovation: it was the first calendar wristwatch to indicate, in addition to the date, the day of the week spelt out in full in an arc-shaped window at 12 o’clock on the dial – a technical feat at the time. Made exclusively of precious metals – 18 ct yellow, white or Everose gold or 950 platinum – and accompanied by its emblematic President bracelet, its multiple dials make it the ideal canvas for self-expression.
