According to a hisotrical summary published in the February 5, 1895 issue of the Jewelers' Circular and Horological Review, the Brooklyn Watch Case Company was established in 1869 and incorporated in 1873. The factory was located at Fourth Ave and Warren St. in Brooklyn, New York.

Crossman reported that the company was started as a private enterprise in 1865 at 42 Pearl Street in New York City. After a year, the company reorganized and moved to 42 State Street in Brooklyn. Around 1870, the copmany relocated to a larger factory at the corner of Fourth Avenue and Warren Street.

The early company manufactured gold and silver cases. However, the silver case line was dropped in favor of their popular gold line. Eventually, the company introduced gold-filled cases as well.

In 1885, several employees reported that cases were being manufactured below market standards. However, after several cases were taken to be assayed, it was found that these claims were false, with all cases surpassing required specifications. [JC, June 1885]

In 1888, the copmany introduced its "Granger" product line, a double-stock solid gold case featuring a layer of 14K on the outside and a lower karat solid gold on the inside. This innovative line of cases, available in 18, 16, 6, and 0 sizes, found immediate success in the market.

In 1890, the company introduced a case with a patented dust band design. These "dust-proof" cases are uncommon and usually demand a premium in the collector market.

In 1892, the Brooklyn Watch Company resigned its affiliation with the American Watch Case Manufacturers' Association, citing that the company had not manufactured gold-filled cases for more than a year. [JC, January 20, 1892]

In 1893, the company discontinued its "Wheat" case. The same year, Lewis A. Parsons, president of the company, died from a stroke. His son, Frederick E. Parsons, who served as the company's treasurer, died in August 1893 from malaria. The deaths of this father/son duo caused disruption in the momentum of the company.

In 1894, the Brooklyn Watch Case Company was absorbed by the Fahys Watch Case Company. Fahys consolidated the offices and relocated the existing stock of the company. However, the company continued to manufacture and sell cases using the popular Brooklyn Watch Case Company name. George E. Fahys, son of Joseph, became president of the Brooklyn Watch Case Company. In 1896, production was also consolidated to the Fahys factory in Sag Harbor, Long Island. A separate entity, Joseph Fahys & Co. became the general sales agent for both companies.

In 1909, the company published advertisements exhibiting an assay test of one of their 14K cases achieved a result of 13.92 Karat Fineness, exceeding the government required specification of 13.50K (including solder). The advertisement positioned the company result at the top of a list of similar 14K cases from other manufacturers. Interestingly, the company followed up the result with another advertisement later in the year exhibiting a score of 14.29 Karat Fineness.

Advertisements for the Brooklyn Watch Case Company appear to have ceased around 1912. Joseph Fayhs died in 1915.

In September 1919, the capital for the company was reduced from $100,000 to $5,000. This move suggests that Fahys fully absorbed the Brooklyn in 1919. No advertisements or mentions of the Brooklyn Watch Case Company have been found after this date. Fahys continued to produce standard Brooklyn cases under the Fahys brand.

Since its early years Brooklyn Watch Case Company maintained close associations with Wheeler, Parsons & Co., Wheeler, Parsons & Hayes, Hayden W. Wheeler & Co., and the Fahys Watch Case Company.
