The Jaeger-LeCoultre Master Ultra Thin Grand Feu watch is the interpretation of the Master Ultra Thin 1907 with a Grand Feu enamel dial. The case of the Master Ultra Thin Grand Feu is crafted from white gold and features the same blade-shaped profile as the Master Ultra Thin 1907, although its thickness has been marginally increased to 5.04 millimetres in order to accommodate beneath the sapphire crystal the various enamel layers applied to the dial (white gold base). You can see the dial bears the inscription “Email Grand Feu” between the 7 and 8 o’clock numerals.
