Due to its technical complexity and limited mid-century production run, the 4261 is considered a foundational piece in the brand's chiming watch history. On the secondary market, these timepieces typically command prices in the mid-to-high six-figure range.

Collectors prioritize this reference because it was the first automatic minute repeater with a perpetual calendar, powered by the 467-part Caliber R 27 Q. The platinum variant is particularly rare, as the majority of the estimated 120 total units were cased in yellow gold. Early examples feature cases hand-forged by Jean-Pierre Hagmann, identified by his hallmark on the lug. The dial displays the day, month, leap year, 24-hour cycle, and moon phase. On the secondary market, platinum 3974 models typically command prices between $1,200,000 and $2,000,000 depending on provenance and condition. A notable auction result occurred at Christie’s in 2022, where a platinum specimen with a black dial and Breguet numerals sold for over $2.5 million, reflecting the premium placed on rare dial configurations."}, "score": 15, "why_compare": "Shared search intent: calendar, minute; similar platinum case profile.", "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "top_listing": null, "auction_comp_count": 3, "review_url": "https://mostexpensivewatches.net/it/review/patek-philippe-3974", "alternatives_url": "https://mostexpensivewatches.net/it/alternatives/patek-philippe-3974"}]}
