Jaeger-LeCoultre Ultra Thin Limited Q1342550 Chocolate Dial

Opening Context
Jaeger-LeCoultre has been closely associated with ultra-thin watchmaking for more than a century, and the Master Ultra Thin collection distils that experience into some of the Maison’s most restrained modern watches. Reference Q1342550 belongs to that tradition, pairing a manually wound movement with a 38 mm rose gold case and an unusually rich chocolate-brown dial.
Produced as a limited edition of 575 pieces, the reference stands apart from the more conventional silver and black-dial Master Ultra Thin models through its warmer palette and distinctly period character.

Why This Reference Matters
The appeal of the Q1342550 lies in how little is required to give the watch identity. Applied rose gold Arabic numerals and dagger-shaped markers sit against the dark brown dial, while the polished case and dauphine-style hands reinforce the classical proportions. There is no date, seconds display or additional complication competing for attention; the design is intentionally reduced to hours and minutes.
Inside is the manually wound Calibre 849, one of Jaeger-LeCoultre’s notably thin hand-wound movements. The movement itself measures approximately 1.85 mm thick and offers around 35 hours of power reserve, allowing the complete watch to remain exceptionally slim.
That mechanical simplicity is central to the reference. The interest comes from proportion, thinness and finishing rather than complication.

On the Wrist
At 38 mm and approximately 6.5 mm thick, the Master Ultra Thin wears with a very low, elegant profile. The diameter gives it enough presence for modern wrists, while the slim case allows it to sit almost flush against the wrist and disappear easily beneath a cuff.
The chocolate dial and rose gold case make the watch warmer and more expressive than many ultra-thin dress pieces. In softer light the dial can appear almost black; under stronger illumination the brown tone becomes considerably more apparent. On a black leather strap with rose gold pin buckle, the overall effect remains formal while allowing the dial colour to carry most of the personality.

Condition & Transparency
This example is presented on a black leather strap with an 18K rose gold pin buckle. Specific information regarding case condition, polishing history, dial and hand condition, crystal, strap originality, box and papers, limited-edition number and previous servicing has not been provided. These details should therefore not be assumed. Documented examples of the reference are often seen on brown alligator straps, so the originality of this individual black strap should be confirmed separately rather than inferred.

Why It Belongs in a Collection
The Q1342550 suits a collector who appreciates Jaeger-LeCoultre at its most restrained. It has none of the mechanical theatre of a Reverso complication or perpetual calendar; instead, it demonstrates the Maison’s ability to make an exceptionally thin, simple watch feel considered through proportion and movement architecture alone.
Within a broader collection, the chocolate dial also gives it a distinct role. It offers the elegance of a traditional rose gold dress watch without falling into the more predictable silver-dial formula, making it particularly appealing for collectors who value subtle variation over obvious complication.

Closing
The Jaeger-LeCoultre Master Ultra Thin Q1342550 is a study in reduction: a 38 mm rose gold case, chocolate dial, two hands and the slender manually wound Calibre 849. Its appeal is quiet and proportion-driven, with the limited-edition execution adding just enough individuality to one of Jaeger-LeCoultre’s purest modern dress-watch designs.
