Jaeger LeCoultre Master Q6011420

The Master Ultra Thin Perpetual reference Q6011420 represents Jaeger LeCoultre's approach to combining perpetual calendar complications with ultra-thin case construction. This reference features a silver dial configuration within the Ultra Thin series, positioning it as a dress watch interpretation of the perpetual calendar complication. The 39mm stainless steel case houses an automatic movement and incorporates a sapphire crystal. The fixed bezel maintains clean lines consistent with the ultra-thin design philosophy. Water resistance extends to 50 meters, providing basic protection for daily wear. The silver dial creates a monochromatic aesthetic against the steel case construction. This reference appeals to collectors seeking perpetual calendar functionality in a refined case size and material combination. The stainless steel construction and 39mm diameter offer accessibility within the perpetual calendar category, while the silver dial provides a classic color option. The automatic movement eliminates manual winding requirements for regular wear.
