Introduced at SIHH in 2008, the Ultra Thin line capitalized on Jaeger-LeCoultre's prowess in the manufacture of ultra-thin in-house watch movements. Although most used Cal. 849, the company's thinnest movement, the Master Grande Ultra Thin instead used the proven (if thicker) Cal. 896.

This is undoubtedly one of the great classics of the ultra-slim watch a beautiful model with a simple and clear dial and graceful body. Through the sapphire crystal caseback the noble manufacture movement can be admired.
