Jaeger-LeCoultre Grande Reverso Night & Day
Introduced at SIHH in 2014, the Night & Day shares most of its case dimensions with the existing Grande Reverso Ultra Thin Duoface, measuring 46.8 mm tall, 27.4 mm wide, and 9.14 mm thick. Although it shares a case with a Grande Reverso Ultra Thin watch, the Night & Day was classified into the regular Jaeger-LeCoultre Grande Reverso line.
The primary innovation in the Night & Day is Cal. 967B, one of very few automatic movements used in a Reverso watch to date. The only previous automatic Reverso watches, apart from the Squadra and Gran'Sport series, were the Reverso Grande Taille Automatic and Reverso Grande Automatique. This is a modification of the Cal. 967A found in the 39 mm stainless steel version of the Rendez-Vous Night & Day.
