The Waltham Watch Company was a company that made watches a long time ago. They started making watches in the year 1850, when people didn't have phones or computers to tell time, so they needed watches to know what time it was. The company was based in a town called Waltham in Massachusetts, in a country called the United States of America.
The Waltham Watch Company made watches that were very good and accurate, which means they always showed the correct time. The watches were made by very skilled people who knew how to put all the tiny pieces together to make the watch work. The watches were made in a big building called a factory, which is like a big puzzle where people make different parts and then put them all together to make the watch.
The watches made by the Waltham Watch Company became very famous and people all over the world wanted to buy them. The company became so famous that they started making watches for the military and for important people. The watches were so popular that many other companies started making watches too, but the Waltham Watch Company was still the most popular.
However, after many years, people started using phones and computers to tell time instead of watches. This made it hard for the Waltham Watch Company to sell as many watches as they used to, and eventually they went out of business. Today, some people still collect the watches made by the Waltham Watch Company because they are very special and remind them of a time long ago when people wore watches every day.
