Reference 4148420 belongs to Jaeger-LeCoultre's Master Control collection, a line long associated with disciplined design and mechanical refinement. The 40mm round stainless steel case houses a scratch-resistant mineral crystal and a fixed bezel, while a transparent case back opens a view onto the automatic Calibre 866AA movement within.
The silver-tone dial arranges alternating Arabic numerals and index markers around its perimeter for clear, classical legibility. Complementing the silver-toned hands, the dial integrates a day and date display at 12 o'clock and a moon-phase complication at 6 o'clock — two complications rendered without crowding the dial's considered layout.
The watch is worn on a leather strap secured by a deployment clasp with push-button release, offering a secure and comfortable fit for everyday use. This example is dated 2024 and is presented complete with its original box and papers.
