Summary of new CVSTOS watches for 2021

Challenge Chrono III-S

A new titanium case and white dial model has been added to the Challenge Chrono III-S, the cutting-edge model in the Challenge Chrono series. The Challenge Chrono III-S, which strongly embodies the three concepts of CVSTOS - "high-tech," "sporty," and "elegant," is a model inspired by super sports cars.

The luxury of a super sports car and the presence and beauty of its mechanism are expressed through the case, skeletonized dial, and movement. This model features a white dial center, bridge, faceplate, and strap. A small seconds hand featuring the Tomoe crest, the symbol of Sicily, is located at 9 o'clock. The "5" and "7" indexes are decorated with red accents reminiscent of racing stripes. The case is crafted from grade 5 titanium, creating a thick, powerful case while remaining lightweight and comfortable to wear.

Challenge Chrono III-S ARTA Limited Edition

　The Challenge Chrono III-S, inspired by super sports cars, has been joined by the Challenge Chrono III-S ARTA Limited Edition, a collaboration model with Autobacs Seven's racing sports brand, ARTA. The ARTA logo is placed on the inner bezel at 12 o'clock, and the CVSTOS model is the first to feature a navy blue movement. The crown, push buttons, dial, and back side feature orange accents, the image color of the ARTA racing team. The case is made of high-strength, lightweight grade 5 titanium, perfectly suited to the world of super sports cars.

Challenge Sealiner PS Automatic

　The Challenge Sealiner PS Automatic has been added to the Challenge Sealiner series, aimed at yacht sailing and cruising enthusiasts. Like many Challenge Sealiner models, the bridge of this model features stripes of teak, a material often used in boat decks and luxury furniture.

Teak wood has beautiful grain and durability, and ages beautifully, making it a key element of this watch's worldview. It also features a small seconds hand at 6 o'clock, shaped like a ship's screw. To accommodate this large, heavy screw-shaped small seconds hand at 6 o'clock, two innovations were incorporated into this model: a new gear train was added that draws power from the escape wheel, and weak permanent magnets were attached to the back of the screw and the movement to stabilize the screw. These efforts ensure that there is no strange movement during operation.
