The 42mm case is constructed from a stabilized resin composite containing genuine Vacherin Mont d’Or cheese, paired with a cowhide strap. It features a red fumé dial with white indices, mimicking the Swiss flag, and houses the hand-wound caliber HMC 327 with a 72-hour power reserve. While the original cheese-cased watch was a singular prototype, Moser also produced the Swiss Alp Watch on which the silhouette is based. The Swiss Mad Watch sold at a Christie’s charity auction in 2017 for 102,500 CHF. Because it is a unique piece, it does not have a standard secondary market range, though its historical significance as a satirical protest piece maintains its value in the high five-figure to low six-figure bracket."}, "lang": "fr", "url": "https://mostexpensivewatches.net/fr/alternatives/h-moser-cie-8327-1400", "reference_url": "https://mostexpensivewatches.net/fr/reference/h-moser-cie-8327-1400", "review_url": "https://mostexpensivewatches.net/fr/review/h-moser-cie-8327-1400", "listing_stats": {"count": 12, "median": 19950.0, "low": 10750.0, "high": 98000.0, "brands": 1, "merchants": 2}, "auction_comp_count": 1, "alternatives": [{"reference": {"slug": "h-moser-cie-1804-1201", "brand": "H.

Moser & Cie. Endeavour Centre Seconds Concept reference 1200-0400 was introduced around 2015 as a limited edition of 10 pieces. This reference is defined by its 40.8mm 18k red gold case and a signature \"Concept\" dial, which omits all indices, logos, and branding to emphasize the fumé sunburst finish. It houses the in-house caliber HMC 200, a self-winding movement featuring a Straumann hairspring and a three-day power reserve. Collectors value this specific model for its role in establishing the brand’s minimalist design philosophy and its extreme scarcity compared to later non-limited Concept releases. On the secondary market, this reference typically commands prices between $20,000 and $28,000 depending on condition and provenance. While the 1200-0400 is no longer in production, its success led to the permanent integration of logo-free dials into the broader Endeavour collection."}, "score": 4, "why_compare": "Shared search intent: cie, moser.", "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "top_listing": null, "auction_comp_count": 0, "review_url": "https://mostexpensivewatches.net/fr/review/h-moser-endeavour-concept-red-gold", "alternatives_url": "https://mostexpensivewatches.net/fr/alternatives/h-moser-endeavour-concept-red-gold"}, {"reference": {"slug": "longines-27748", "brand": "Longines", "ref": "27748", "model": "Type A-7 Avigation", "case_material": "Chrome Plated", "provenance": "extracted_from_auction_comps", "url": "https://mostexpensivewatches.net/reference/longines-27748", "description": "The Longines Type A-7 Avigation reference 27748 was produced during the mid-1930s for the U.S. Army Air Corps. Collectors prioritize this reference for its 51mm chrome-plated base metal case and its unique 41-degree offset dial, designed to allow pilots to read the time without releasing flight controls. The watch contains the caliber 18.72 manual-wind monopusher chronograph movement. Due to the corrosive nature of the chrome plating and the rigors of military use, examples in original, well-preserved condition are rare. On the secondary market, these timepieces typically command prices between $20,000 and $40,000 depending on provenance and dial state. A notable production detail is the \"U.S. Army A.C.\" engraving on the caseback, which distinguishes authentic military issues from civilian counterparts.

It houses the manual-wind Calibre 861 movement, the same caliber utilized in the Speedmaster Professional of that era. The dial typically features a matte black finish with oversized luminous markers and a distinctive orange central chronograph hand. Because these were internal prototypes and never reached mass production, they are exceptionally rare, with only a few known examples in private hands.
