“The watch has two faces. A small clock face is attached to the movement, a large face is pulled up to a high tower and exposed so that people can see the time. Inside the machine attached the small clock, there is a clockwise shaft in line with the large clock outside. Therefore, we just need to adjust the small clock inside, the clock outside the tower is also automatically adjusted, ”said Mr. Tinh. Photo: dantri

One of the most special things is that this Time Machine is manufactured manually and the operator must pull the cable to run it every 24 hours. Photo: dantri

Mr. Tinh also added that in the past, when the clock's presence was not as popular as today, people would hear the bell ringing to know what time it was, especially at night. The ringing of a clock can spread far away in good weather. Photo: dantri

For Mr. Tinh, this watch is not only a valuable hand-made thing, but also a witness of history, culture and scientific inventions.
