OVERVIEW
THE QUINTESSENTIAL DRESS WATCH
UNDERSTATED ELEGANCE
The Master Ultra Thin Moon embodies the ultimate combination of technical understatement and sleek aesthetics. Its design and slimness ensure that it is a subtle and elegant watch on your wrist.
SOPHISTICATED CODES
The silvered grey sunray-brushed dial creates a subtle play of light, complemented by gilt hour markers and Dauphine hands. At 6 o’clock, the moon-phase display reveals a polished pink gold-coloured moon and stars against a deep midnight blue sky, encircled by a pointer date. Its design offers an understated presence that sits naturally on the wrist.
REFINED PROPORTIONS
Slim and refined, the Master Ultra Thin Moon in pink gold showcases pure lines shaped by a thin bezel, elongated lugs and perfectly balanced proportions. Designed in 36 mm, its case retains the collection’s signature aesthetic codes. Its thinness, polished surfaces and gently curved lugs create a harmonious silhouette, reflecting the Maison’s expertise in ultra-thin watchmaking.
LEGACY OF THIN CALIBRES
Inspired by the Maison’s remarkable legacy of ultra-thin watches – created from the early 1900s onwards – the Master Ultra Thin collection was conceived as the quintessential dress watch for the 21st century.
HIGH-PERFORMING HEART
Calibre 925 features fine decorative finishes, including Côtes de Genève, bevelling and blue screws. Designed, manufacture and assembled under one roof at Jaeger-LeCoultre’s Manufacture in Le Sentier, it offers high reliability and a power reserve of 70 hours.
MADE IN OUR MANUFACTURE
From its calibre to its case, every Jaeger-LeCoultre watch is designed, manufactured and assembled under one roof, at our Manufacture in the Vallée de Joux. Our obsession with quality is renowned as every Jaeger-LeCoultre model undergoes strict “1,000 Hour Control” testing. This unique program provides internal certification tests that far exceed official chronometry tests. It includes movement testing before and after casing and extends throughout assembly, according to conditions that match daily wear. A quality seal is engraved on the back of every watch once it meets our strict standards.
