Jaeger-LeCoultre Master Grande Tradition Tourbillon Perpetual

About this reference

The Jaeger-LeCoultre Master Grande Tradition Tourbillon Perpetual reference 186.2.35.S (Q1652420) was introduced around 2010 and remained in production for approximately five years. Collectors target this reference for the Calibre 987, an automatic movement that integrates a silicon escapement with a flying tourbillon and a perpetual calendar. The 42mm case is constructed from 18k pink gold, featuring a silvered grained dial with applied hour markers and a dedicated year aperture. This model represents a specific era where the manufacture focused on combining high complications with modern materials like silicon to improve chronometric stability. On the secondary market, this reference typically trades in the $45,000 to $65,000 range depending on the presence of original documentation. A notable production detail is the limited nature of these high-complication pieces, which were produced in significantly lower volumes than the standard Master Control series.
