Collectors prioritize this reference for its bespoke movement developed by Jean-François Mojon and finished by Kari Voutilainen, featuring a 14mm flying balance wheel suspended above dual independent time zones. The 44mm case houses a high-domed sapphire crystal and a vertical power reserve indicator, marking the brand’s transition from futuristic designs to nineteenth-century aesthetics. On the secondary market, this reference typically trades between $65,000 and $85,000 depending on condition and completeness. While the initial launch included 18k white gold, the pink gold variant is noted for its contrast against the NAC-treated bridges. A \"Final Edition\" in stainless steel concluded the series, but the pink gold remains the definitive original configuration."}, "listing_stats": {"count": 7, "median": 75000.0, "low": 42000.0, "high": 110000.0, "brands": 1, "merchants": 3}, "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}, {"id": "h_7380631322707", "title": "MB&F MB&F x H.
