Collectors prioritize this reference for its movement, the Calibre LM Perpetual, developed by Stephen McDonnell. Unlike traditional modular perpetual calendars, this 581-component manual-wind movement utilizes a \"mechanical processor\" with a default 28-day month to prevent date-skipping errors and damage during adjustment. The platinum case measures 44mm by 17.5mm and features a blue face with a suspended 14mm balance wheel positioned above the sub-dials. On the secondary market, this specific platinum edition typically trades in the $160,000 to $210,000 range depending on condition and provenance. A notable production detail is that this reference preceded the \"EVO\" iterations, retaining the original high-domed sapphire crystal and 30-meter water resistance rating characteristic of the early Legacy Machine aesthetic."}, "listing_stats": {"count": 1, "median": 110000.0, "low": 110000.0, "high": 110000.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_7400856158291", "title": "MB&F Legacy Machine Perpetual Evo | Titanium", "brand": "MB&F", "model": "Legacy Machine Perpetual Evo | Titanium", "reference": "WTI_M1886", "price_usd": 110000.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Grade 5 Titanium", "case_size_mm": 40.0, "movement": "Automatic", "complications": [], "merchant_slug": "a-collected-man", "merchant_name": "A Collected Man", "image_url": "https://cdn.shopify.com/s/files/1/0606/5325/files/52505532a3f35f70fbf72a389aa9e2f3.jpg?v=1720090902", "detail_url": "https://mostexpensivewatches.net/listing/h_7400856158291", "buy_url": "https://mostexpensivewatches.net/out/h_7400856158291", "available": true}], "auction_lots": []}
