Jaeger LeCoultre 172.2.79.S Master Ultra Thin 18K Rose Gold Gray Dial

The Jaeger‑LeCoultre Master Ultra Thin reference 172.2.79.S is a distinguished ultra‑slim dress watch released circa 2012 to celebrate JLC’s 175th anniversary as a limited edition of 575 pieces. Its 38 mm case in 18 k rose gold houses the in‑house manual‑winding Caliber 849, renowned for its wafer‑thin profile and refined finishing, offering a 35‑hour power reserve. The exhibition caseback reveals the movement’s elegant architecture, underscoring JLC’s mastery of slim haute horlogerie. The gray dial variant, though less common than the black or ivory versions, adds a subtle modernity to this otherwise classically proportioned timepiece. With just 50 m of water resistance, it remains firmly in the realm of elegant formal wear, while its slender 4.3 mm thickness ensures it slips effortlessly under a shirt cuff. Collectors prize this reference for its commemorative significance, technical purity, and rarity within the Master Ultra Thin family. The combination of limited‑edition provenance, superb manual caliber, and timeless minimalism makes it a compelling acquisition for discerning connoisseurs.
