A small watch that appeared from the Chinese tomb 400 years ago

It is said that clocks came out from the grave 400 years ago in the Guangxi Autonomous Region of China, so that they are bothering archeologists.

Details are as below.
Ananova - Swiss watch found in 400 - year - old tomb

It is said that the clock was discovered when Mr. Jiang Yanyu, former director of the Guangxi Autonomous Region Museum, paid the soil on the coffin of the grave. Suddenly a piece of stone collapsed and fell to the ground and made a metal noise so I found a rugged object. In addition, it seems that it turned out that it is a clock when paying the soil of the object and looking it up. The hands of the clock showed 10:06 AM and the back was engraved with the word "Swiss".

The watch discovered.


The local archaeologists are confused because the tomb in which the clock was discovered was believed not to have been devastated from the Ming Dynasty period 400 years ago, and the excavation is temporarily interrupted and the specialty coming from Beijing It seems to wait for the house to reveal a mystery.

It usually looks like a ring clock to be used for watches as usual, but why is this something like this coming out?
