Introduced in 2020 as the first-ever combination of a chronograph and triple calendar in the Master Control line, it manages to pack day, date, month, moon phase, and a column-wheel chronograph into a case that's only 12.05mm thick — a feat that most manufacturers would need significantly more real estate to pull off. The Caliber 759 uses a vertical clutch for seamless chronograph engagement and a column wheel for precise switching, and it delivers 65 hours of power reserve on a full wind. The silver sunray dial keeps everything readable despite the complication count, with two subdials, a moon phase window, and calendar apertures arranged cleanly across the face. A pulsometric scale on the dial flange adds a vintage-inspired detail that nods to the collection's instrument-watch heritage. At 50 meters of water resistance with a screw-down caseback, it's built for daily wear — and the movement visible through the sapphire exhibition back is finished to a standard that justifies every minute spent looking at it.\u003c\/p\u003e\u003cp style=\"margin:0\"\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp style=\"margin:0\"\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\u003cp style=\"margin:0\"\u003e\u003cbr\u003e\u003c\/p\u003e\u003cul style=\"margin:0;padding-left:1.5em\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e Master Control Chronograph Calendar\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReference:\u003c\/strong\u003e Q4138420\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaliber:\u003c\/strong\u003e Jaeger-LeCoultre 759 — 41 jewels, 28,800 vph (4 Hz), column wheel chronograph with vertical clutch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase Material:\u003c\/strong\u003e Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase Diameter:\u003c\/strong\u003e 40mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase Thickness:\u003c\/strong\u003e 12.05mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBezel:\u003c\/strong\u003e Stainless steel, fixed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrown:\u003c\/strong\u003e Stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrystal:\u003c\/strong\u003e Sapphire\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaseback:\u003c\/strong\u003e Sapphire crystal exhibition\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial:\u003c\/strong\u003e Silver sunray with pulsometric scale on flange, dauphine hands, applied markers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrap:\u003c\/strong\u003e Brown Novonappa calfskin with stainless steel folding clasp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMovement:\u003c\/strong\u003e Automatic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Reserve:\u003c\/strong\u003e 65 hours\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Resistance:\u003c\/strong\u003e 50 meters (5 bar)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctions:\u003c\/strong\u003e Hours, minutes, small seconds, chronograph (30-minute counter), triple calendar (day, date, month), moon phase\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp style=\"margin:0\"\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp style=\"margin:0\"\u003e\u003cstrong\u003eCondition Report\u003c\/strong\u003e\u003c\/p\u003e\u003cp style=\"margin:0\"\u003e\u003cbr\u003e\u003c\/p\u003e\u003cul style=\"margin:0;padding-left:1.5em\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase:\u003c\/strong\u003e 10\/10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBezel:\u003c\/strong\u003e 10\/10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrystal:\u003c\/strong\u003e 10\/10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial\/Hands:\u003c\/strong\u003e 10\/10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrap:\u003c\/strong\u003e 10\/10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClasp:\u003c\/strong\u003e 10\/10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCaseback:\u003c\/strong\u003e 10\/10\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp style=\"margin:0\"\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp style=\"margin:0\"\u003e\u003cstrong\u003ePolishing Status:\u003c\/strong\u003e Unpolished\u003c\/p\u003e\u003cp style=\"margin:0\"\u003e\u003cstrong\u003eDelivery Contents\u003c\/strong\u003e\u003c\/p\u003e\u003cp style=\"margin:0\"\u003e\u003cbr\u003e\u003c\/p\u003e\u003cul style=\"margin:0;padding-left:1.5em\"\u003e\u003cli\u003eComplete set — box, papers, warranty card, manuals\u003c\/li\u003e\u003c\/ul\u003e\u003cp style=\"margin:0\"\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp style=\"margin:0\"\u003ePlease refer to photos for full contents.\u003c\/p\u003e\u003cp style=\"margin:0\"\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp style=\"margin:0\"\u003e\u003cstrong\u003eService \u0026amp; Authenticity\u003c\/strong\u003e\u003c\/p\u003e\u003cp style=\"margin:0\"\u003e\u003cbr\u003e\u003c\/p\u003e\u003cul style=\"margin:0;padding-left:1.5em\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eTimegrapher:\u003c\/strong\u003e 282 amplitude\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eService History:\u003c\/strong\u003e No known service history\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e Base warranty expired — card dated April 2023, base coverage ended April 2025.
