Jaeger-LeCoultre Master Control Date Stainless Steel / Silver

About this watch

The Jaeger-LeCoultre Master Control Date Q4018421 debuted in 2025. A refined take on the classic three-hand dress watch, this 40 mm stainless steel model reflects the Master Control collection’s mid-century inspiration with subtle updates for the modern wrist. The silvered grey dial features dauphine hands, applied markers, and a neatly framed date window at 3 o’clock. The slim case measures just 8.78 mm thick and features both polished and satin-brushed surfaces. Inside ticks the automatic calibre 899, offering a 70-hour power reserve and operating at 28,800 vibrations per hour. The Q4018421 is delivered on a light-brown Novonappa® calfskin strap and includes a complimentary black alligator strap. Both straps are easily interchangeable, secured by a stainless steel double folding clasp.
