Watch Info
Manufacturer: Jaeger-LeCoultre
Model: Master Control Perpetual Calendar
Condition: Excellent (Pre-Owned)
Reference: Q1618420
Year: N/A
Box: No
Papers: No
Accessories: Watch Only. Includes original Jaeger-LeCoultre strap and clasp.
Notes: The Q1618420 is Jaeger-LeCoultre's most intellectually compelling expression of the Master Control collection — a perpetual calendar of genuine manufacture depth housed in a refined 39mm stainless steel case. Driven by the in-house Calibre 868, the perpetual calendar mechanism automatically accounts for months of varying length and leap years through 2100, requiring no manual date correction for the life of the watch. The silver dial's layout is a masterclass in legible complication design — day, date, month, and leap year indicator arranged with the clarity and restraint that defines the Master Control aesthetic. This is a watch that does something genuinely extraordinary while looking as though it isn't trying at all.

Dial, Hands, & Crystal: The silver dial is flawless, with no marks, scratches, or discoloration. The applied indices and hands are in perfect condition. The sapphire crystal is mint and free of any chips or edge nicks.

Why the Master Control Perpetual Calendar is JLC's Most Underrated Complication
Jaeger-LeCoultre is one of the few manufactures in Switzerland capable of producing a perpetual calendar entirely in-house — movement, case, and finishing — and the Master Control is the most accessible expression of that capability. Where perpetual calendars from more celebrated maisons carry price premiums driven largely by brand positioning, the JLC equivalent delivers the same horological substance at a fraction of the cost, in a case size and aesthetic that transitions effortlessly from desk to dinner.
In the current 2026 market, perpetual calendars represent one of the strongest value propositions in serious watchmaking — mechanically complex, genuinely useful, and increasingly sought after as collectors move away from simple three-hand sports watches toward meaningful complications. The Q1618420, offered here in excellent condition on its original strap and clasp, is an exceptional entry point into perpetual calendar collecting from one of Geneva's most respected manufacture ateliers. For the collector who wants genuine horological substance without the inflated premium of a more hyped name, this is the answer.
