Collectors prioritize this reference for its bespoke movement developed by Jean-François Mojon and Kari Voutilainen, featuring a 14mm suspended balance wheel oscillating above dual independent white lacquer dials. The 44mm case houses a manual-wind caliber with a 45-hour power reserve and a vertical power reserve indicator. As the first round-cased timepiece from a brand previously defined by avant-garde shapes, it represents a pivotal shift in MB&F’s design history. On the secondary market, the LM1 red gold typically trades between $65,000 and $85,000. A notable Final Edition was released in 2017, limited to 18 pieces in stainless steel, marking the definitive end of the LM1 production run."}, "listing_stats": {"count": 7, "median": 75000.0, "low": 42000.0, "high": 110000.0, "brands": 1, "merchants": 2}, "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", "alt_buy_urls": [{"partner": "goldsmiths", "name": "Goldsmiths", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_7400856158291/via/goldsmiths"}, {"partner": "selfridges", "name": "Selfridges", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_7400856158291/via/selfridges"}, {"partner": "farfetch", "name": "Farfetch", "region": "Global", "url": "https://mostexpensivewatches.net/out/h_7400856158291/via/farfetch"}], "available": false}, {"id": "h_7380631322707", "title": "MB&F MB&F x H.
