CVSTOS Challenge Tourbillon Gustave Eiffel Bronze Steel Skeleton Watch Limited Editon

The CVSTOS Challenge Tourbillon Gustave Eiffel represents a striking tribute to Parisian engineering and modern high watchmaking. Its signature tonneau-shaped case is crafted from high-performance steel treated with a rich bronze-colored PVD coating, intricately sculpted with Eiffel’s famous St. Andrew’s Cross structural motifs. This openwork design offers a dramatic sense of depth, allowing light to pass freely through the structural chassis.

Underneath the curved, anti-reflective sapphire crystal lies a completely skeletonized bimetallic dial. At the 6 o'clock position, the mesmerizing 12mm flying tourbillon cage performs a full rotation every minute, acting as the small seconds indicator. The open gear-train barrel at 12 o'clock mirrors the historical machinery of the Eiffel Tower’s elevators. Powered by the hand-wound mechanical Calibre CVS2600 with a robust 60-hour power reserve, the movement is mounted to three distinct bridges that isolate the gear train from mechanical tensions. Completed with a hand-stitched brown alligator leather strap, this watch is an exceptional collectible celebrating historical triumph and contemporary luxury.
