The Master Control Reveil is a discreet complication piece that brings Jaeger-LeCoultre's alarm tradition into a 39mm rose gold case. Its silver dial keeps the watch classical and balanced, and the date adds everyday use without upsetting the layout. The automatic movement adds practical ease while preserving the distinct appeal of a mechanical alarm. At 14mm thick on an alligator strap, it has the measured presence collectors look for in this line.
