When master watch manufacture Ludwig Oechslin originally produced this watch for Ulysse Nardin, it became one of the most powerful continuous calendars on the market. Perpetual Ludwig allows all calendar exhibits to be adjusted back and forth using one crown, avoiding returning this timepiece to the manufacturer in the event of an incorrect setting. Unlike the standard handle system, this timepiece includes the first perpetual calendar device driven by wheels and also gears. <p>high quality replica watches</p>
