Columbus Watch Co. Columbus, Ohio 1874-1903 Dietrich Gruen, born in Osthofen, Germany in 1847 stated a business as he Columbus Watch Co. on Dec 22, 1874. At the age of 27, he received a U.S. patent for an improved safety pinion. the new company finished movements made for Madretsch, Switzerland, a suburb of Beil. The imported movements were made in a variety of sizes and were in nickel or gilt. The early watches usually had the initials. C.W. Co. intertwined in script on the dial. The serial numbers generally ran up to around 20,000 a few examples are in the 70,000. D. Gruen and W.J. Savage decided in 1882 to manufacture watches locally. By 1883 the first movements were being produced with a train consisting of 72 teeth on the barrel, 72 on the center wheel, 11 on the center pinion, 60 on the third wheel with a pinion of 9, 70 on the fourth wheel with a pinion of 9 with a 7 leaf escape pinion. The new manufacture primarily made 18 size movements but also pioneered the 16 size watch, while reducing the size and thickness. Several new innovations were used into the design, including a completely covered mainspring barrel, a new mircometric regulator and the ability to change the mainspring without removing the balance cock. By 1884 they were making their own dials, but no cases were ever manufactured. The company went into receivership in 1894 with new management. That same year Frederick Grewen started again as D. Gruen and Son. They had Paul Assmann to produce 18 size & 16 size movements with 18 & 21 jewels with the escapement designed by Moritz Grossman of Glasshute. Soon after this time movements were obtained form Switzerland and he new Gruen ver-thin movement was developed. In 1898 this company moved to Cincinnati. From 1894 through 1903 the Columbus Watch Co. produced watches both under the Columbus Watch Co. and the New Columbus Watch Co. names. The re-organized company produced the same models but switched primarily to named grades such as the Time King and Columbus King. The higher grade watches were assigned a special block of serial numbers from 500,000 to 506,000. In keeping with the industry several models with 25 jewels were produced in this block of numbers. In 1903 the Columbus Watch Co. was sold to the Studebakers and the South Bend Watch Co. started. The machinery, unfinished movements, parts and about 3/4 of the employees moved to South Bend, Indiana. Some marked Columbus Watch Co. movements were finished by South Bend. Examples exist of dials made in the South Bend style and movements marked Columbus Watch Co.
