OVERVIEW
UNIQUENESS: A COPPER-COLOURED DIAL ADORNS THE MASTER ULTRA THIN
DESIGN
THE QUINTESSENTIAL DRESS WATCH
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.
WARM AND DISTINCTIVE COPPER-COLOUR
A grained dial in a soft shade of copper brings fresh and contemporary allure to the Master Ultra Thin Moon. As the subtle texture catches the light from different angles, the colour shifts between a soft, almost powdery shade to a more saturated tone of copper.
A SOPHISTICATED BALANCE
Complementing the sleek lines of the case, the dial layout is a finely judged exercise in symmetry and balance. A combined moon phase and date display brings a strong visual identity: a silver moon is set against a deep blue background decorated with stars and, encircling the moon phase aperture, the dates are transfer-printed in black on the terracotta dial background.
HERITAGE
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.

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.
