About the Jaeger-LeCoultre Master Ultra Thin
The line runs from a three-hander to a minute repeater on the same idea. The Master Ultra Thin Date and Moon at 39 mm are the core, with the 925AA and its 70-hour reserve in 15 references, the 868/1 with its moon phase in 11, and the 899/1 of the 40 mm Date in 10. The hand-wound 849, 1.85 mm high, powers the Ultra Thin 1907 and, cut open, the Squelette; the Tourbillon and the Perpetual add the complications without leaving the proportions. 87 of the 97 references are automatic.
The 39 mm case accounts for 49 references and the 40 mm for 22, with 34 mm to 38 mm ladies' and smaller models and a few at 41 mm. Pink gold is the material of 50 cases, steel of 31 and white gold of 14. Silver dials lead at 38, and the ivory-coloured dial of the Moon and the Réserve de Marche accounts for 27. 12 references carry a tourbillon and the moon phase is the collection's most common complication. Water resistance is 50 m on 88 references, and 89 have a display back.
The Master Control is the sibling with a thicker case and the chronograph, the Master line holds the Grand Tourbillon and the Gyrotourbillon, and the Reverso is the maison's other thin watch.
