Several of the original Waltham factory buildings are still standing, and were added to the National Register of Historic Places in 1989.In addition to using grade numbers, Waltham also used many grade names on their watches, often choosing the names of Board members, company investors, or other prominent individuals.His experience ranges from legal affairs reporting to covering the Middle East.He served stints as a newspaper and magazine editor in Saudi Arabia and the United Arab Emirates.A lip or notch on the case back can be found at the 6 or 12 o’clock position. At or near the edge of the movement will be a serial number.If there is no lip, carefully wedge the blade into the seam and lift. Carefully examine the case back of a Waltham pocket watch. Press down on the crown and a tiny hatch will release the cover. Digits in the serial number will range from two to eight depending on the year of production.Their vision was to form a watch company that could produce high-quality watches at a lower cost using interchangeable parts.With financial backing from Samuel Curtis, of small-arms manufacturing fame, the watch production began in 1851, and the first small group of watches were finished in late 1852.
It is still possible to purchase modern quartz watches that bear the Waltham name, but these watches are unrelated to the "genuine" American Waltham Watch Company.
The first watches produced went to officials of the company, and it was not until 1853 that the first watches were offered for sale to the public.
Problems were encountered with the new production methods.
Waltham continued to manufacture watches (and clocks) until 1957, when they ceased production and became the Waltham Precision Instrument Company.
The rights to the name "Waltham Watch Company" were sold to the Hallmark Watch Company of Chicago, Illinois who continued to sell imported watches using the Waltham name.
