Jaeger-LeCoultre Master Grande Tradition Tourbillon Cylindrique Perpetual Platinum

This Master Grande Tradition Tourbillon Cylindrique à Quantième Perpétuel Jubilee Edition (Ref. Q5046520) was inaugurated in 2013 to commemorate Jaeger‑LeCoultre’s 180th anniversary as a highly exclusive limited edition of 180 pieces. Cased in extra‑white platinum at a refined 42 mm diameter and 13.1 mm thickness, the piece houses the automatic in‑house Calibre 985, a fully hand‑finished movement featuring a flying tourbillon with a cylindrical balance‑spring, perpetual calendar (day, date, month, four‑digit year), moonphase, and a seconds display via the tourbillon — a rare confluence of complications that underscores JLC’s reputation as the “watchmaker of watchmakers.” The grained silver dial is meticulously layered to accommodate calendar subdials and tourbillon aperture, offering superb legibility and balance. With parts count of 431, 49 jewels, a 48‑hour power reserve, and oscillating rose‑gold rotor engraved with the 1889 Paris Universal Exhibition medallion, the movement blends historical significance with technical prowess. The piece’s rarity as a platinum Jubilee release, its technical sophistication and superior finishing, make it a benchmark for collectors seeking top‑tier horological artistry.
