This uniquely masculine 18K rose gold A. Lange & Söhne 1815 Tourbillon was unveiled in 2014 by the Swiss maker. It features a striking rhodium solid silver dial that shows time using blue-steeled hour and minute hands and black Arabic numeral hour markers and seconds using a small seconds subdial at 6 o'clock. The small seconds display is integrated expertly with the watch's tourbillon-in-a-cage complication, giving the dial an immaculate look. The transparent case back of the watch allows a peek at the revolutionary caliber L102.1 manual winding movement. This watch uses a brown crocodile leather strap with tang clasp.
