Collectors value this reference for its manual-wind, in-house movement featuring a 2.5Hz flying balance wheel positioned beneath a central sapphire dome. The grade 5 titanium case measures 54mm by 45mm and utilizes a unique \"jaw\" mechanism that functions as a power reserve indicator; the teeth close as the 45-hour mainspring winds down. Time is displayed via two rotating aluminum domes for hours and minutes. This model represents a technical evolution of the brand’s animal-themed \"Machine\" lineage. On the secondary market, the HM10 Titanium typically trades in the $85,000 to $110,000 range. While the titanium version features blue accents, a notable variant exists in 18k red gold and titanium, which often commands a higher premium at international auctions."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "mb-f-hm10-panda-only-watch-2021", "brand": "MB&F", "reference": "HM10 Panda Only Watch", "model": "Horological Machine No. 10 'Panda' Only Watch", "case_material": "Stainless Steel and Titanium", "hammer_usd": 679160, "year_sold": 2021, "venue": "Christie's Geneva", "lot_summary": "A unique piece created for the Only Watch 2021 charity auction, transforming the HM10 'Bulldog' into a panda with black and white lacquer and movable 'leg' lugs.", "source_url": "https://www.christies.com/en/lot/lot-6344574", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/mb-f-hm10-panda-only-watch-2021"}, {"slug": "mb-f-hm10-bulldog-2021", "brand": "MB&F", "reference": "HM10 Bulldog", "model": "Horological Machine No. 10 'Bulldog'", "case_material": "Titanium", "hammer_usd": 81193, "year_sold": 2021, "venue": "Christie's Hong Kong", "lot_summary": "A titanium 'Bulldog' model featuring a red dial and a unique power reserve indicator displayed through the opening and closing of the 'jaws'.", "source_url": "https://www.christies.com/en/lot/lot-6344574", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/mb-f-hm10-bulldog-2021"}]}
