The manta ray is extremely sensitive to its living environment and serves as one of the indicator species for marine ecosystems. We capture its graceful, agile silhouette and integrate it into mechanical watch aesthetics on the wrist, embodying reverence for and commitment to marine conservation. This watch is equipped with the self-developed CAL 9301 3D curved bionic non-hairspring regulator flying tourbillon movement. The movement adopts a symmetrical dual-barrel parallel structure with a 60-hour power reserve and a 4Hz vibration frequency. The tourbillon bridge undergoes three-dimensional sculpting and mirror polishing, bringing to life two elegant, fluid manta rays. Interdependent and protective of one another, they symbolize the close symbiotic relationship between humanity and the ocean.
