8401

An upscale iteration of the 8400, itself derived from the 8500. This self-winding movement features a Co-Axial escapement for enhanced precision, stability, and longevity, and withstands magnetic fields exceeding 15,000 gauss. It utilizes a free-sprung balance with a silicon hairspring, dual series-mounted barrels, and bidirectional automatic winding, finished with a red gold balance bridge and oscillating weight featuring arabesque Geneva waves.
