It houses the in-house HUB1242 Unico movement, an automatic flyback chronograph with a column wheel visible through the skeletonized dial. The watch represents a significant milestone in the brand's history of material innovation, specifically the industrialization of shaped sapphire.

This caliber is a self-winding flyback chronograph with a column wheel visible on the dial side. The skeletonized dial features transparent resin components and luminescent hands to maintain the monochromatic aesthetic. Collectors value this reference as the foundational model for Hublot’s transparent series, representing a technical achievement in machining extremely hard materials.

It utilizes the caliber 956, a self-winding movement featuring a redesigned peripheral gong that allows for a thinner case profile of 12.39mm while maintaining the signature \"school bell\" alarm tone. Collectors value this model for its silver sunray dial with a central rotating alarm disc and the inclusion of a date complication. On the secondary market, this reference typically trades between $9,000 and $12,000 depending on condition and completeness.

This reference is the only split-seconds chronograph ever manufactured by the brand, and it was never offered for public sale, having been commissioned as gifts for professional racing drivers. The watch features a Valjoux 55 VBR 17.5-ligne movement housed in an oversized 44mm stainless steel case, which is unusually large for the era. Only 12 examples were produced, and only eight are currently accounted for by scholars. Due to its extreme rarity and historical significance as the most complicated Rolex ever made, the reference 4113 commands prices in the multi-million dollar range on the secondary market. In 2016, a well-preserved example sold at a Phillips auction for approximately $2.4 million, and prices have since remained at the top tier of the vintage watch market.", "score": 20}, {"slug": "universal-gen-ve-124113", "brand": "Universal Genève", "ref": "124113", "model": "Compax", "case_material": "18k Yellow Gold", "provenance": "extracted_from_auction_comps", "url": "https://mostexpensivewatches.net/reference/universal-gen-ve-124113", "description": "The Universal Genève Compax reference 124113 was produced during the 1940s and 1950s, featuring a 37mm case constructed from 18k yellow gold.

The dial typically features a three-register layout with tachymeter and telemeter scales, often paired with leaf or syringe hands and applied gold hour markers. Its oversized case dimensions for the era and the use of precious metal distinguish it from the more common steel variants of the Compax line. On the secondary market, prices generally range from $8,000 to $15,000 depending on the preservation of the case facets and dial originality.

Collectors value this reference for its faithful 37mm monobloc case construction, integrated bracelet with hexagonal center links, and the Maltese cross emblem at five o'clock. Unlike the original caliber 1121, this version utilizes the in-house self-winding caliber 2455/2, which operates at 4Hz and features a quick-set date function visible through a sapphire caseback. On the secondary market, prices typically range from $65,000 to $85,000, often carrying a premium over its retail price due to high demand.

The technical appeal lies in the juxtaposition of precious metal with industrial titanium and the specific gem-setting on the bezel, typically featuring baguette-cut semi-precious stones like amethysts, citrines, or tsavorites that match the rubber-backed alligator straps.
