another enlargement wing for tool, die equipment and machinery. The addition was one hundred feet long by thirty feet in width and was three stories high. In 1943, the building was further enlarged with the addition of new office space bringing the overall size of the plant to three stories and . Products The Star Watch Case Company designed, manufactured and assembled watch cases for a plethora of watchmakers. The movements (mechanisms), dials, hands, crystals (glass watch faces), and some of the crowns (buttons used to wind the watch) were made by other vendors and shipped to Star for final assembly. Star's watchmaker clients included Manistee Watch Company, Hamilton, Longines, Elgin, Gruen, Omega and Pulsar. Until World War I the company manufactured pocket watch cases exclusively. They were available in solid gold, gold filled, sterling silver, rolled nickel-silver or brass. Styles included open face and hunting cases. After the war, wristwatch cases were added to the product line. Government procurement The company produced thousands of watches during World War I that could easily be seen without removing them from pockets. Pocket watch cases were Star's major product until the United States entered the World War II. Then the factory was converted to making brass compass cases, small weapons components, and submarine parts. During the war, the company's reputation for making quality stainless steel military watch cases and cases for military compasses grew. Additionally, the company manufactured elements of military navigational aids. It also made components for the top secret Norden bombsight, used for accurate airborne bombing. Star Watch Case Company made cases for the Omega Speedmaster Professional, worn by Eugene A. Cernan on a trip to the moon, commonly referred to as the "Moonwatch." Other similar Star models were worn on various space missions. Edward H. White wore a Speedmaster during his Gemini 4 spacewalk. Ed Mitchell wore a Speedmaster on Apollo 14. Neil Armstrong wore a Speedmaster on Apollo 11. Design A Star employee, Andrew Hallberg, developed a proprietary pantograph which increased production speed by allowing up to 32 watch backs to be engraved simultaneously, making it much more efficient than hand engraving. The cutting-edge, mass-production technology was closely guarded from competitors, giving the company an advantage in accelerated watch case production. It is a device that can copy and scale, in the instance of Star Watch Case, various engravings on the reverse side of a watch case using
