In celebration of its 15th anniversary, CVSTOS is announcing the "Challenge Chrono III-S," the most advanced model in the Challenge Chrono series.

CVSTOS advocates new luxury based on the three concepts of "high-tech," "sporty," and "elegant." Staying ahead of the times and trends, CVSTOS has combined the finest materials needed for modern lifestyles to elevate its flagship collection to the next level through tireless pursuit of quality.

The Challenge Chrono III-S series is a series that pursues luxury reminiscent of a super sports car. Attention to detail is evident in the ultimate curves that evoke a sense of speed, the mechanically designed skeletonized mechanical components, and the design that emphasizes the multi-component structure. The "S" in the model name stands for "SPORTY," further emphasizing the functionality, individuality, and innovation of the style and details. The case design features subdivided case parts for a three-dimensional, stylish structure.

The "Challenge Chrono III-S" collection embodies a tireless spirit of challenge, pursuing meticulous engineering and design. In addition to luxurious 18KRG x titanium, the collection also offers titanium cases made from the same material but with different shades for a more sleek look. The newly designed tonneau case features bold, thick case sides and side guards and crown guards, enhancing practicality for today's active owners. While maintaining a powerful volume, the primary material has been changed from stainless steel to titanium, resulting in further weight reduction and corrosion resistance.

The dial also features innovative touches. Arabic numerals and bar indexes are rhythmically arranged, the hour and minute hands have been redesigned into sharp sword hands, and the small seconds hand at 9 o'clock has been redesigned with the Sicily symbol (tomoe crest). The three-dimensionally set vertical counters include a minute counter at 12 o'clock and an hour counter at 6 o'clock. The small seconds hand at 9 o'clock is set slightly back and has been adjusted to appear even more three-dimensional on the skeleton dial. Two small windows are installed within a single counter at 3 o'clock, allowing the date and power reserve to be checked. The power reserve has been updated from a classic fan-shaped display to a modern digital display.

While the hour display is the main focus, the functions and design have been researched and developed to ensure clear visibility of the chronograph function's measurement values, embodying CVSTOS' philosophy as a "pioneer of time," always ahead of its time while maintaining its unchanging core. The Challenge Chrono III-S series, with its sleek body, titanium and mixed materials, and skeletonized design that reveals the mechanical structure of the movement, exudes the power and speed of a super sports car. The Challenge Chrono III-S, crafted through tireless research and refinement of its technology and techniques, sets a new standard, perfectly embodying the three philosophies of "sportiness," "luxury," and "elegance."


Titanium Grade 5

Grade 5 titanium is the highest grade of titanium alloy, accounting for less than 30% of all titanium alloys. Primarily used in the aerospace industry, its applications include aerospace airframes (jet engine compressor blades, discs, and rings, as well as rocket engine cases and helicopter rotor hubs) and engine components, as well as key non-aerospace applications in the offshore and power generation industries, where it is used for critical parts requiring high strength and light weight. The technical data for this titanium alloy is that it is composed of 90% titanium, 6% aluminum, 4% vanadium, 0.25% iron, and 0.2% oxygen, and has physical properties far stronger than those of pure titanium (grades 1 to 4).It is a material that embodies the identity of CVSTOS, with outstanding corrosion resistance, excellent strength, lightness, non-magnetic properties, and fire resistance.
