This Three-in-One timepiece earns its name from featuring three complications: tourbillon, minute repeater, and perpetual calendar.

The dial features ancient Chinese characters to display the month (12 o'clock), date (3 o'clock), day of the week (9 o'clock), and moon phases (6 o'clock).

The patterns on the edge of the dial are inspired by the 商周铜龙首 (Bronze Loong Head from the Shang and Zhou Dynasties), an ancient Chinese musical instrument unearthed at the Jinsha site in Chengdu, China. Link to this instrument on Jinsha Site Museum Website (last one on the page) ↗
