Ulysse Nardin Classic Perpetual Ludwig

Posted on by

Master watchmaker Ludwig Oechslin was renowned for his knack of finding the most direct solutions to the most complex problems. It was his genius for finding simplicity in complexity that was behind the first perpetual calendar timepiece in 1996.

A watch that enabled forward and backward date adjustments using a single crown was unprecedented in Haute Horlogerie, and especially one that relied on so few components. Now, the Classic Perpetual Ludwig pays homage to the legend with a vintage-styled edition.

The iconic UN-33 perpetual calendar movement is the beating heart of this eternal classic, behind the calendar settings on the dial – the big date in its double window, month, day and year – as well as the small seconds. Streamlined sty-ling enhances the beauty of the silver dial with blue hands, resting in a 41 mm steel case that is water resistant to 30 m.
