This reference is significant for being the first LM101 model to feature a steel case, a material rarely used by the brand outside of the Performance Art series. It houses the LM101 caliber, which was the first movement developed entirely in-house by MB&F, featuring a 14mm bespoke balance wheel suspended above the dial. The aesthetic is defined by a sunray purple dial plate and high-contrast white lacquer sub-dials for time and power reserve. On the secondary market, this specific reference typically trades in the $80,000 to $110,000 range. A notable production detail is that this 2021 edition introduced the \"Evo\" style technical updates to the standard LM101 line, including a larger dial opening and the removal of the \"Legacy Machine\" engraving on the movement bridges."}, "listing_stats": {"count": 5, "median": 75000.0, "low": 42000.0, "high": 110000.0, "brands": 1, "merchants": 3}, "listings": [{"id": "h_7400856158291",
