Jaeger-LeCoultre Master Control Reveil

About this reference

The Jaeger-LeCoultre Master Control Reveil reference 141.8.97 (or 141.840.970) was produced from approximately 1995 through the early 2000s. Collectors value this reference for its caliber 918, a 22-jewel automatic movement featuring a mechanical alarm with a dedicated hanging gong, which provides a clearer resonance than earlier pin-struck designs. The 39mm stainless steel case is notable for its "Master Control 1000 Hours" gold medallion on the caseback, signifying it was among the first lines subjected to the brand's rigorous six-week testing protocol. The silver sunray dial features a central rotating alarm disc and a date aperture at 3 o'clock. On the secondary market, this reference typically trades between $5,000 and $7,500 depending on condition and accessories. A notable variant is the limited boutique edition featuring a black dial, which often commands a premium over the standard silver production models.
