Twenty~4 (Olive Green, Diamond-Set)

The Twenty~4 launched in 1999 as Patek's first collection built exclusively for women: a rectangular case on an integrated bracelet, quartz-powered, unveiled at Baselworld that year on the wrists of four female Patek employees rather than behind glass. Reference 4910 continues that original design largely unchanged today; a separate, round Twenty~4 Automatic arrived only in 2018 under a different reference, with its own case shape and movement.

This Patek Philippe Twenty~4 wears a 25.1mm x 30mm steel case with diamonds set along the case flanks and an olive green sunburst dial. Calibre E15 quartz inside, on a steel bracelet.

Fun fact: the name is a lifestyle pitch, not a case reference: Patek positioned it as elegant enough to wear all twenty-four hours of the day, boardroom to dinner, the same idea behind debuting it on employees' wrists in 1999 instead of in a display case.
