Jaeger-LeCoultre was founded in 1833 in Le Sentier, Switzerland, in the heart of the Vallée de Joux, and is one of the few manufactures able to develop and produce internally virtually every component of its movements, from escapements to hairsprings.
The Master collection groups the manufacture's classic dress watches, and within it the Ultra Thin line represents the specific pursuit of maximum slimness without sacrificing an in-house automatic movement.
This reference, the Q1238480, launched in 2024, runs Caliber 899, an automatic movement Jaeger-LeCoultre produces internally, with 32 jewels and a 38-hour power reserve, housed in a case just 7.8mm thick for a 39mm diameter.
The sunray-finished blue-grey dial, with elongated indexes and dauphine hands, is completed by a date window at 6 o'clock and a display case back showing the movement's finishing. This reference is clearly distinct from the other three Jaeger-LeCoultre models already in Cazador's catalog: the Reverso Duoface has a reversible case with two dials, the Polaris Automatic is a sports watch with diving heritage, and the Master Control Date runs a different caliber within the same Master collection; the Master Ultra Thin Date, by contrast, is the manufacture's specific proposition centered on an ultra-thin profile. [UNVERIFIED: we do not confirm whether this specific reference remains in active catalog beyond July 2026].
