The bezel features an additional 48 baguette-cut stones in a gradient pattern. It utilizes the in-house Caliber HUB1242 Unico movement, an automatic flyback chronograph with a 72-hour power reserve and a visible column wheel on the dial side. On the secondary market, this model typically commands prices between $65,000 and $85,000 depending on condition and completeness.
