Frederique Constant Watch Highlife Quartz Ladies FC-240SD2NH6B. Frederique Constant launched the first models in the Highlife collection over 20 years ago.Their unique design was characterised by the special strap built into the case. In 2020, the brand updated the ingenious concept and reinvigorated the collection by adding three new models: the Highlife Perpetual Calendar Manufacture, Highlife Heart Beat and Highlife Automatic COSC. All still feature the system which makes it possible to switch between a steel bracelet, a leather, croco calf suede or rubber strap, alternating from classic to sporty on a whim! In 2021, the Highlife Worldtimer was added to the collection as well as ladies’ styles.
