The Master Calendar is a highly regarded, complicated dress watch that beautifully balances Jaeger-LeCoultre's deep horological history by pairing a classic triple calendar layout with a practical power reserve indicator. Though cataloged as a formal dress watch, the Q151242A leans on the substantial side. At 13.1mm thick, it has a presence on the wrist that prevents it from feeling too delicate. This Master Calendar watch easily slides under a sports jacket or standard suit cuff with the lugs curving downward gently, allowing it to sit flat and comfortably on wrists down to 16cm in circumference.
Visible through the display caseback, the Caliber 924 is a showcase of high-end Swiss engineering and exquisite finishing: It features circular Côtes de Genève, engine-turned pearlage, and kiln-fired blued screws. Driven by a unidirectional winding system rolling on ceramic rotor bearings, weighted by a heavy 22-karat gold winding mass.
