Pre-Owned Duometre Quantieme Lunaire Steel (Q604848J)

Pre-owned, this Jaeger-LeCoultre Duomètre Quantième Lunaire Q604848J presents a 42.5mm stainless steel case built around the patented Dual-Wing concept, uniting independent timekeeping and complication gear trains within a single regulating organ. Continuing Jaeger-LeCoultre's tradition of manufacture ingenuity, the Duomètre line pairs horological complexity with the quiet restraint expected of a Grande Maison timepiece.

• Dual-Wing Architecture: The patented Duomètre mechanism employs two independent barrels and gear trains linked to a single regulating organ, one dedicated to timekeeping and the other to the calendar and moon phase functions.
• Jumping Seconde Foudroyante: A flying seconds hand advances in 1/6th-second jumps, allowing the wearer to read fractional-second precision at a glance.
• Case & Strap: The 42.5mm, 13.05mm-thick stainless steel case combines polished, brushed, and micro-blasted finishes, fitted to a blue alligator leather strap with quick-release technology on a stainless steel double folding buckle.
• Dial: A blue gradient dial combines opaline, satin, circular, and sunray finishes across its subdials, framing the moon phase display and twin power-reserve indicators.
• Movement: Powered by the manual-winding Calibre 381, a 42-jewel movement built from 414 components, delivering 50 hours of power reserve to both the timekeeping and complication trains, finished with Geneva stripes and hand-chamfered bridges visible through the sapphire caseback.
• Full Set: Accompanied by original Jaeger-LeCoultre box, instruction booklet, and warranty card dated 2026.
• Near-Mint Condition: Movement running well with case and strap in near-mint condition (9.5/10).
