Question: who used the american system of manufactures to produce clocks

title: Waltham Watch Company
text: In early 1962 , Massachusetts Institute of Technology ( MIT ) engineers began work on the Apollo navigation system . The engineers ' starting point was MIT 's revolutionary guidance system , which included gyroscopes and instruments for measuring changes in direction . The guidance system was high mechanical technology , like the precision parts in a watch . MIT . engineers , students and staff , led by Dr. Charles Stark Draper , worked closely with the Waltham Watch Company . The MIT team learned how to work with high precision machining while under the operation and direction of military contractor Raytheon Space and Information Systems Division Waltham Operations . Mechanical gyroscopes , spinning with ever - higher precision , very low friction , and very low wear , required the utmost accuracy and absence of even the most minute defect . Nobody had ever tried to manufacture precision instruments that would work with such accuracy before the Waltham team . It is said that the hygiene and cleanliness rules of the team were so strict that women were not allowed to wear makeup and if someone had just come back from a sunny vacation , they were forbidden to work near the assembly area for fear that they could have skin flaking off from their suntans .
