The idea started in April of 2015 with designing 16S salesman cases. It is US based company with manufacturing facility in Taiwan. United States made the best watches in the world, not Swiss. The movements are so amazing, craftsmanship is unparalleled in the world. The requirement of Railroad Grade specification is so stringent, it challenged American watch makers to the level no others can meet. The objective of Classic Watch Case Co. USA is to let the world know and appreciate these masterpieces and remember their legacy etched in history. However, the beauty is encased where no one can see it, so Classic Watch Case Co, USA intends to produce clear back cases (or now commonly known as display salesman cases) so collectors can appreciate and showcase the pride of ownership. USA is founded by American pocket watch collector. We, at CWCCO, USA know that all of the watch case companies of the past do not survive the economy because the demand is not enough to sustain the company. Similarly, CWCCO, USA will also face similar fate. But, we would like to invest and promote pocket watch collection to younger generation of collectors.
