Jaeger-LeCoultre Master Control Perpetual Calendar

About this reference

The Jaeger-LeCoultre Master Control Perpetual Calendar reference 140.6.80.S in platinum was produced during the mid-to-late 1990s and early 2000s as part of the initial Master Control series. Collectors value this reference for its 37mm case diameter and the caliber 889/440/2, which features a perpetual calendar module designed by Kurt Klaus. The platinum variant is distinguished by its silver sunray dial, blued steel hands, and a moon phase indicator at the 12 o’clock position. Unlike modern iterations, this model utilizes a solid case back secured by four screws, bearing the gold Master Control medallion. On the secondary market, this reference typically trades between $18,000 and $24,000 depending on the presence of the original platinum deployant buckle and service history. A notable production detail is the limited nature of the platinum run compared to the more common steel and yellow gold versions.
