The 3970EP-038 is a specific platinum execution from the fourth series, distinguished by its 36mm case with a screw-down sapphire caseback and a black dial featuring diamond hour markers. It utilizes the manual-wind Caliber CH 27-70 Q, based on a Lemania 2310 ébauche, which collectors value as the first Patek Philippe perpetual calendar chronograph movement not based on a Valjoux blank. This reference represents the transition from vintage to modern proportions and manufacturing techniques. On the secondary market, the 3970EP-038 typically commands prices in the mid-to-high six-figure range, often between $180,000 and $250,000 depending on provenance. A notable production detail is that while standard platinum 3970s featured baton markers, the diamond-dial 038 variant was produced in significantly smaller quantities, increasing its rarity among fourth-series examples.", "score": 209}, {"slug": "a-lange-sohne-424-038-triple-split", "brand": "A.

Collectors value this reference for its integration of the ultra-thin Calibre PF517, an automatic movement featuring a micro-rotor and a flying tourbillon positioned at 7 o’clock. The 40mm 18k pink gold case utilizes the signature Toric aesthetic, characterized by a hand-knurled bezel inspired by Doric columns. The dial features a hand-guilloché \"Grain d'Orge\" pattern and Javelin-shaped hands. Due to the labor-intensive finishing and low production volume of the PF517 movement, these pieces are produced in limited quantities annually. On the secondary market, this reference typically trades in the $60,000 to $85,000 range.
