Government Buys Timing Machines 

In the Government Air Service, where seconds are precious and timepieces must be accurate, WATCHMASTER watch rate recorders have been designated to keep timepieces on time.

After extensive trials and tests of Western Electric recorders over a period of years, the Army Air Corps has just ordered nine WATCHMASTERS from American Time Products, Inc., New York.

These instruments will be used at important air bases where they will produce printed records of watch rates and performance and indicate the causes of any irregularities.
