A technical outlier in Jaeger-LeCoultre's Master Control line, this Master Compressor Memovox brings the collection's disciplined design language into a more robust stainless steel format. The black dial and 41.5mm case give it a crisp, functional look that feels purposeful rather than ornate. Its automatic movement pairs a date display with the Memovox alarm, one of the manufacture's most distinctive practical complications. At 14mm thick, it wears with modern substance and a decidedly sporty stance.
