Jaeger-LeCoultre Master Control Chronograph Calendar — Ref. Q4138180

Video footage available upon request. Open to offers. Bracelet sizing service available.


The Master Control Chronograph Calendar is Jaeger-LeCoultre at its best — quiet complexity from a manufacture that built its reputation supplying movements to the biggest names in Swiss watchmaking. This reference packs a column-wheel chronograph, triple calendar, moonphase, and pulsometric scale into a clean, balanced 40mm layout that never feels busy. The blue sunray-brushed dial shifts beautifully in the light, and the rhodium-finished dauphine hands and mixed markers keep everything legible across all the complications. Powered by the in-house Caliber 759 — featuring a vertical clutch for seamless chronograph engagement and 65 hours of power reserve — this is the kind of watch that rewards a closer look every time you check it. Delivered with both a stainless steel bracelet and a blue calfskin strap on the quick-change system, it goes from the office to the weekend without missing a beat.
