The Tlalpan Watch Museum is a museum that specializes in the preservation and display of antique clocks, as the oldest clocks in its collection, including those dating back 500 years, are still in operation! Its collection consists of a huge variety of hourglass, sundial, water and candle clocks, as well as a wide range of phonographs, gramophones, and old radios. As well as a great café, it's a great place to learn and enjoy the history of antiques at the same time.
