Jaeger LeCoultre Q8008520 (Pre-owned - Good) — USD 8,550 on eBay

The Master Ultra Thin Reserve de Marche reference Q8008520 represents Jaeger LeCoultre's approach to thin dress watches within their Master collection. This particular reference combines the Ultra Thin series characteristics with power reserve indication, positioning it as a complications-focused variant within the model range. The 39mm case is constructed from 18k rose gold and fitted with a sapphire crystal. A silver dial provides the display surface, while the fixed bezel maintains clean proportions typical of dress watch design. The automatic movement powers the functions, and the case offers 50 meters of water resistance. This reference appeals to collectors seeking a precious metal dress watch with additional functionality beyond basic timekeeping. The rose gold case material and power reserve complication distinguish it from simpler three-hand variants within the Master Ultra Thin lineup, making it suitable for those prioritizing both technical interest and formal aesthetics.
