Hamilton watch company, established in 1892, began as a by-product of the 13-acre facilities of the lancaster and keystone watch companies of lancaster, pennsylvania. after purchasing the illinois watch company in 1928, hamilton would go on to have roughly half the market share of

railroad watches in the u.s. ultimately, their production in wristwatches

 would garner them what some considered as the highest quality of american watch manufacturing. hamilton's u.s. production would halt by 1969 and they would ultimately be sold to a predecessor of the modern swatch group by the mid-1970's.
