About this watch
The Jaeger-LeCoultre Master Control Geographic Q4128421 debuted in 2025. This stainless steel wristwatch features a 40mm case with a silvered grey sunray-brushed dial. The layout includes a second time zone display at 6 o’clock, accompanied by a city disc for global time zone selection, as well as a power reserve indicator and date sub-dial.
It is powered by the automatic 939AA, which offers hours, minutes, small seconds, date, second time zone, power reserve, and world city indicator functions. The movement is visible through a sapphire crystal case back and delivers a power reserve of approximately 70 hours. The watch is delivered with a light brown calfskin leather strap and an additional black alligator leather strap, both secured with a stainless steel folding clasp.
