This reference utilizes the manual-wind caliber developed by Stephen McDonnell, characterized by its 14mm balance wheel suspended above the dial while the anchor and escape wheel are positioned beneath the movement. The 44mm case houses a dial plate finished with a traditional hand-frosted texture, a signature aesthetic of the Legacy Machine collection. Collectors value this specific reference for its lightweight construction and the technical complexity of the split escapement architecture. On the secondary market, these timepieces typically trade in the low-to-mid six-figure range, often between $110,000 and $140,000 depending on condition. A notable production detail is that this titanium edition followed the initial 2017 launch of the four gold launch editions."}, "score": 13, "why_compare": "Same mb&f collector universe; shared search intent: legacy, machine.", "listing_stats": {"count": 2, "median": 75885.0, "low": 74000.0, "high": 77770.0, "brands": 1, "merchants": 2}, "top_listing": {"id": "h_7226297909335", "title": "MB&F MB&F Legacy Machine Split Escapement EVO", "brand": "MB&F", "model": "MB&F Legacy Machine Split Escapement EVO", "reference": "40992012", "price_usd": 77770.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": [], "merchant_slug": "analog-shift", "merchant_name": "Analog/Shift", "image_url": "https://cdn.shopify.com/s/files/1/0809/1255/files/AS09739_40992012_MBF_LEGACYMACHINE-6.jpg?v=1730498372", "detail_url": "https://mostexpensivewatches.net/listing/h_7226297909335", "buy_url": "https://mostexpensivewatches.net/out/h_7226297909335", "available": false}, "auction_comp_count": 2, "review_url": "https://mostexpensivewatches.net/ja/review/mb-f-04", "alternatives_url": "https://mostexpensivewatches.net/ja/alternatives/mb-f-04"}]}
