Time Museum in Tehran is a precious work in a very beautiful building in the north of the city. The mansion where the museum is located in has many fantastic plaster, tile and muqarnas works and a very eye catching garden. The interior parts are design with a combination of Iranian and foreign architecture; there is a room in this museum called Isfahaniha that is heavily inspired by the Ali Qapu Palace in Isfahan. In the Time Museum in Tehran you could get familiar with the different devices used to estimate the time in the past from the premier example of analogue watches and clocks to the newer versions.  The first examples of clocks such as sand clocks are located in the green area of the museum so you would enjoy both watching them and breathing the fresh air. Many wrist watches are also shown on the second floor. Alaedin Travel could provide you with excellent tour to Iran so you could visit its awesome attractions.
