Democratic complications

The Perpetual Calendar Tourbillon Manufacture timepiece embodies the founders’ visionary quest to render Swiss watchmaking savoir-faire and innovation more accessible.

In 2004, after a few years of research and development, Frederique Constant introduced its first in-house patented manufacture movement: the award-winning Heart Beat Manufacture Calibre. Four years later, the brand unveiled its first in-house manufacture Tourbillon, one of the industry’s most intricate complication based on the Heart Beat Manufacture calibre.

Later in 2016, to celebrate the 10th year anniversary of the Frederique Constant manufacture in Plan-les-Ouates, another grande complication was created: the Manufacture Perpetual Calendar watch, paving the way for a new generation of Swiss Made complicated watches at an accessible price tag and becoming a beacon of the brand’s know-how and expertise.

The movement

Aiming to provide ultimate precision, the in-house automatic FC-975 movement is equipped with a silicium escapement wheel and anchor. This specific material counters problems caused by the effect of the earth’s gravity when the movement is in a vertical position and is resistant to temperature change.

This grand complication also bears a smart weight balance wheel and a delicate and even Tourbillon cage. Frederique Constant patented its Tourbillon cage composed of 80 components all produced with a precision of 1-2 micron (0.001-0.002 mm) thanks to its CNC machines. In order to achieve the highest degree of precision, small weights are added in the Tourbillon’s cage to obtain a perfect balance. When the Tourbillon is constructed, the cage’s stability is slightly off, as the escapement wheel and anchor are decentred. Frederique Constant added a “smart screw” system on the outer edge of the Tourbillon to equalize the weight and deliver a perfect balance within the cage, resulting in a more stable amplitude and rate.

The watch

The Meteorite Tourbillon Perpetual Calendar Manufacture Only Watch model is a unique piece presented in a 42mm diameter 3-part 18K rose gold case with a see-through case back to let one admire the delicate Perlage & Côtes de Genève decorations.

The watch features a stunning, skeletonized blue tint meteorite dial. This four billion-year-old, very rare material fell on Earth 80’000 years ago and was found in Namibia, Africa back in 1839.

The Perpetual Calendar complication also displays the day, date and month and requires even less adjustments than an annual calendar. This highly sophisticated complication acknowledges the number of days each month, displays the year and automatically adjust itself on the leap years. Once set, it will remember the months with 30 and 31 days, the 28 days of February as well as the leap year cycle with the return of 29th of February every four years. The Perpetual Calendar doesn’t require any manual correction before 400 years, although there is an exception in the Gregorian Calendar, the watch will need to be adjusted on March 1st, 2100. The hour and minute functions are all adjustable through the crown. The dial presents at 12 o’clock the months and leap year, at 3 o’clock the days and at 9 o’clock the week days.

The tourbillon’s cage sits at 6 o’clock, with its incorporated seconds hand that rotates once every minute.

Frederique Constant decided to develop this one-of-a-kind timepiece and support the 8th edition of Only Watch to finance scientific research for the rare Duchenne muscular dystrophy. The Brand is looking to offer the best fruit of its high-end watchmaking know-how to do good.
