Jaeger-LeCoultre Master Ultra Thin

Jaeger-LeCoultre has been building ultra-thin movements since the 1907 calibre 145, at 1.38mm still among the thinnest ever made, and the Master Ultra Thin is the modern inheritance. At 39mm in steel the case is slim enough to vanish under a cuff, and the dial carries only what it needs: applied indexes, dauphine hands, a sunray finish. The manufacture calibre is made entirely in the Vallée de Joux.
