Emblematic of the pioneering tradition of Swiss Haute Horlogerie, Cvstos oncemore creates a sensation and presents a sporty interpretation that galvanizes the classical veneer of one of the most sophisticated movements in the art of watchmaking: the perpetual calendar.

By integrating Cvstos’ horological philosophy, this perpetual calendar, named Challenge QP-S, unites a sporty and a high-tech character. Nestling in a tonneau-shaped case recognizable at a first glance, this automatic caliber, featuring a 48-hours power-reserve, was designed and assembled by the finest master watchmakers in Switzerland. Elegance and enchantment reach new heights with the moon-phase indicator that complements the technical sophistication of this all-embracing mechanism that displays the calendar and makes the necessary adjustments for leap years.

Relying on an informative approach, the transparency of the sapphire crystal dial attracts the eye towards the complexity that resides in this mechanical memory that indicates the exact date as far ahead as 2100, whichaccording to the Gregorian calendar, is not a leap year. Only then, in the year 2100, will the owner have to adjust the date manually.

Cvstos Technology has decided to produce the case of this astonishing timepiece in steel, palladium or in red gold 5N alloy with its matchless blazing hue. Housed in a water-resistant up to 100 meters case, this model is to be worn with a black rubber strap with a folding clasp.

The Challenge-R 50 QP-S magnificently underscores the well-balanced proportions of its exceptionally large round-shaped case. The imposing visual strength of this case is demonstrated in steel, in titanium or in 5N red gold.

With a round or tonneau-shaped case, the QP-S will definitely perpetuate Cvstos’ timekeeping vision through the years to 2100, and well beyond.
