About this watch
The Jaeger-LeCoultre Master Ultra Thin Moon Q1248421 debuted in 2024.

The silvered grey dial features dauphine hands and a moonphase display at 6 o’clock, rendered in deep blue with golden stars and moon. The date is indicated by a central pointer hand encircling the moonphase aperture.
Inside ticks the automatic calibre 925, delivering a power reserve of 70 hours within a case just 9.3 mm thick. The Q1248421 is paired with a leather strap and secured by a stainless steel double folding clasp. The strap is easily interchangeable for added versatility.
