Setting New Standards in Horology: The CronusArt CM026-003 Supreme Treasure Tourbillon Strikes with an All-Sapphire Case

Published: 24 Jun 2026
Unveiling a new pinnacle in high-end watchmaking, CronusArt presents the CM026-003 Supreme Treasure Tourbillon, a masterpiece with a full sapphire case that challenges the norms of horological design.

Witness the unfolding of a remarkable era in the realm of high-end watchmaking, as sapphire cases continue to evolve from mere technical curiosities into standout signatures of luxe horlogerie. Reserved usually for six-figure timepieces, full sapphire watch construction is a demanding endeavor that necessitates cardinal expertise owing to the hardness of the material and the detailed shaping and finishing it demands. Around this concept, CronusArt has carved its own niche, championing the use of progressive materials like sapphire, carbon fiber, and ceramics. Their latest release, the CM026-003 Supreme Treasure Tourbillon, further pushes horological boundaries, featuring a fully transparent sapphire case that happily houses a tourbillon movement. The watch offers a fresh wave of design aesthetics, despite maintaining a price point significantly lower than competing brands.

The resultant spectacle, once achieved, is a visually-arresting masterpiece where the movement of the watch becomes the hero due to the transparent case. The sapphire casing allows light to pass through, elegantly highlighting the skeletonized mechanics. The watch houses a manually wound CronusArt 36K0-CA907 caliber that deviates from conventional layouts in favor of a visually harmonious design approach. The symmetrical design is emphasized by dual barrels that provide an impressive 65-hour power reserve. The other side of the movement features an eye-catching flying tourbillon, commanding attention with its constant, hypnotic motion - another testament to CronusArt’s commitment to horological innovation.
