The Jaeger-LeCoultre Reverso Classic Medium Duoface Small Seconds made its debut at SIHH 2017. It boasts a sleek and elegant rectangular case measuring 42.9*25.5mm and just 9.2mm thick. Inside, you'll find the hand-wound caliber 854A/2. But what makes this watch truly unique is the back of its case, which can be swiveled to reveal a second, black 'travel time' dial. It's a handy feature for those on the go or when you want to switch up your look.
