Founded in 2005, the CVSTOS brand may be a relative newcomer in the world of Swiss watchmaking, but their dedication to innovation and precision is much celebrated, as are their unique dial designs. 

The Challenge GT II by CVSTOS was a highly limited-edition series. As such, only 28 units of this watch were produced, making this timepiece a challenge to obtain.

However, this watch is more than simply a collectible—it is a veritable racing machine that you can take with you wherever you may roam.

First, let's dig in to the fascinating black-colored and multi-layered partially skeletonized dial. A riot of shapes and capabilities abound.

While SuperLuminova-filled hands and indexes make reading the time a breeze, even in low light, you'll surely appreciate the small seconds at 9 and power-reserve indicator and date functions at 3.

Chronograph functions include a 30-minute counter at 12 and a 12-hour counter at 6. Be sure to note the center red-tipped hand that you can use in conjunction with the tachymeter scale in white running along the outer red edge of the dial.

The unique chunky tonneau-shaped Black PVD-coated ergonomic 316-L stainless steel case measures a hefty 59 x 45 mm and is 16 mm in height. The dashing black rubber strap features a PVD-coated stainless steel deployant clasp.

As a self-winding automatic watch the CVSTOS Caliber 557 beats at 28,800 vph, possesses 25 jewels, and has a 42-hour power reserve. 

Additional features include a domed scratch-resistant sapphire crystal, water resistance, and screw-down winding crown.

From its robust capabilities to its uniquely sporty stylings we believe this CVSTOS Challenge GT II Chronograph will make a thrilling addition to your collection.

Standout features: Highly limited edition of only 28 pieces produced; convenient tachymeter scale and power-reserve indicator; rugged Black PVD-coated stainless steel case and deployant clasp.
