This reference is valued for its manual-wind movement featuring the latest iteration of the single-wheel Co-Axial escapement, a direct evolution of George Daniels’ work. The 38mm or 40mm case houses a multi-part silver dial decorated with hand-turned engine-guilloché patterns and flame-blued steel hands. As Smith produces approximately ten to twelve watches annually across all ranges, the Series 1 is rare, with few examples existing in white gold. On the secondary market, these pieces typically command prices in the mid-to-high six-figure range, often exceeding $600,000 depending on the specific commission details. A notable auction result occurred in 2023 when a Series 1 \"On the Shoulder of Giants\" edition reached a hammer price of approximately $800,000, reflecting the high demand for Smith’s bespoke Isle of Man production.", "score": 187}, {"slug": "roger-smith-series-2-yellow-gold", "brand": "Roger Smith", "ref": "Series 2", "model": "Series 2", "case_material": "18k Yellow Gold", "url": "https://mostexpensivewatches.net/reference/roger-smith-series-2-yellow-gold", "description": "The Roger Smith Series 2 entered production in 2006 as the watchmaker’s first serialized wristwatch, though it remains a low-volume piece with approximately 10 units produced annually. The 18k yellow gold reference is valued for its hand-crafted construction, featuring a three-quarter plate movement caliber equipped with the single-wheel Co-Axial escapement. The dial is composed of silver with hand-turned engine-guilloché patterns and gold chapters, while the 38mm or 40mm case is fabricated using traditional English methods. Due to the extreme scarcity and the transition to the \"Open Dial\" or \"Edition 4\" specifications in later years, early Series 2 examples are highly sought after. On the secondary market, these watches typically command prices in the mid-to-high six-figure range, often exceeding $600,000. A notable auction result occurred in 2023 when a yellow gold Series 2 sold for approximately $1.1 million, reflecting its status as a cornerstone of independent British watchmaking.", "score": 20}, {"slug": "audemars-piguet-5402st", "brand": "Audemars Piguet", "ref": "5402ST", "model": "Royal Oak Jumbo A-Series", "case_material": "Stainless Steel", "provenance": "extracted_from_auction_comps", "url": "https://mostexpensivewatches.net/reference/audemars-piguet-5402st", "description": "The Audemars Piguet Royal Oak 5402ST A-Series was produced between 1972 and approximately 1974, representing the first 2,000 units of the original Royal Oak production. Collectors prioritize the A-Series due to its historical status as the debut luxury steel sports watch and its specific design features, including the \"AP\" logo positioned at 6 o'clock rather than 12 o'clock. The reference features a 39mm monobloc case and the ultra-thin Calibre 2121, developed by Jaeger-LeCoultre. Secondary market prices typically fall within the $100,000 to $200,000 range, though exceptional examples with original \"tropical\" dials or full sets can exceed these figures. A notable production detail is the sequential numbering on the case back; collectors specifically seek the earliest \"A-Series\" designations, as later B, C, and D series moved the logo to the 12 o'clock position and saw higher production volumes.", "score": 8}]}
