Haydon started to design a variety of products for wartime use such as time delay relays, repeat cycle timers, and electromechanics devices.
Most of the designs were classified and even Haydon's management did not know their end use.

During World War II Haydon made an important contribution to the war effort that made it possible for the United States Army Air Corps (now the United States Air Force) to continue its accurate targeting of strategic and tactical targets.
Specifically, reference is made to the Farnsworth Research Bombing Control System    that improved upon the Norden Bombsight.
Farnsworth Research  had assumed that almost any clock company could furnish one important component, a small gear reduction unit, with the necessary clutches and differentials.
After searching the clock industry, it was discovered that their assumption was very wrong.
Their program for the new electronic bombing system was in jeopardy for the lack of this specialized component.
Haydon designed the gear reduction unit for this program by designing a DC motor, patent No.
2,513,410  that was used in aircraft, tanks, submarines, and a variety of portable military equipment so that all of this equipment could be operated by battery supply.
This enabled Haydon to provide  timers for battery operation that had previously required alternating current for synchronous motor operation.

Haydon found that DC timer applications required accuracy far in excess of anything obtainable by the use of any DC motors then available, even with the best centrifugal governor attached.
The only way to obtain the precision timing accuracy required for many applications was to use a crystal oscillator, frequency divider, amplifier, and synchronous motor, the total cost of which was in the neighborhood of $1,000.00 at the time.
This device was about the size of a loaf of bread and weighed approximately 15 pounds.
Such units were made by other companies but only for applications requiring extreme precision.

It was obvious to Haydon that there was a definite need for a much smaller, lighter and less expensive method of producing accurate speed drives for timers and control mechanisms.
So, he developed what is well known in the industry as a Chronometric Governor for his DC motors covered by patent No.
2,523,298.
It was less than 2 inches in diameter and ½” thick, weighed two ounces and sold as part of the motor to which it was attached for approximately $60.00.

This invention gave The A.W. Haydon Company the capability of furnishing precision timers for de-icing, cabin pressurization, microwave tuning, potentiometer time drives and components for
Electronic controls for guidance systems for missiles plus numerous other applications in the aircraft and electronics fields.
