Produced from 1985 to 2007, the 3940 is a foundational reference in the Patek Philippe canon, and the yellow gold ‘J’ variant in ivory white is among its most classically beautiful expressions.\u003c\/p\u003e\n\u003cp\u003eThe luminous ivory lacquered dial carries large Arabic numerals in warm gold, a layout of generous readability that belies the extraordinary mechanical complexity within. Two subsidiary dials at nine and three o’clock display day of week with 24-hour indication and retrograde date respectively, while a generous moon phase aperture at six o’clock frames a dramatic day\/night arc below. Yellow gold sword-shaped hands sweep the cream surface with unhurried elegance. The Cal. 3150 automatic movement — visible through the sapphire caseback with its gold Calatrava-engraved rotor — is a benchmark of finishing and reliability. A rich dark brown alligator strap completes the composition with vintage warmth.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReference:\u003c\/strong\u003e 3940J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Material:\u003c\/strong\u003e 18K Yellow Gold\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDial:\u003c\/strong\u003e Ivory White with Arabic Numerals \u0026amp; Gold Hands\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComplications:\u003c\/strong\u003e Perpetual Calendar (Day\/24H, Date, Month), Moon Phase\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCase Size:\u003c\/strong\u003e 39mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMovement:\u003c\/strong\u003e Automatic Mechanical (Cal. 3150)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStrap:\u003c\/strong\u003e Dark Brown Alligator Leather\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduction:\u003c\/strong\u003e 1985–2007 (Discontinued)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e Geneva, Switzerland\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eA legend of grand complication watchmaking — the 3940J in ivory yellow gold is the perpetual calendar every serious collector aspires to hold.
