Q1238421

The Jaeger-LeCoultre Master Ultra Thin Date Q1238421 debuted in 2025. With its clean lines and restrained elegance, the Master Ultra Thin Date in stainless steel is a study in refined proportions. Its polished 39 mm case measures just 7.89 mm thick, housing an automatic movement with date function. On the silvered sunray-brushed dial, the redesigned elongated hour markers and dauphine hands enhance legibility, while the date aperture now resides at 6 o’clock for a more symmetrical display. The watch is paired with a black alligator leather strap, secured with a stainless steel double folding clasp. Like all Jaeger-LeCoultre watches, the Q1238421 has passed the stringent “1,000 Hours Control” testing regime.
