Designed and developed by Concord's specialist futuristic watchmaking division 'C LAB SERIES' utilizing a movement created by BNB Concept, it features an aerial bi-axial tourbillon held by an arm bridge and secured via a web of steel cables that compensate for temperature variation. One of most visual characteristic of the model is the prominent green liquid of phosphorous nanoparticles that display the 3-day power reserve. The liquid, which rises and falls via a mechanical cylinder, glows in the dark when subject to light.
