Manufacturing Craftsmanship

Hand-assembled by Cartier artisans, the CT0439S undergoes a multi-stage finishing process including precision lens drilling, alignment calibration, and hinge stress testing. The geometric lens edges are cut using diamond-blade equipment to ensure perfect symmetry and clarity.
