American Waltham Watch Co. was in operation from 1852-1957 and was an American pocket watch manufacturer. Manufacturing of Waltham watches took place at their facility in Waltham, Massachusetts.

We believe this 1907 dial captures a sunrise over the Atlantic along the East Coast of the United States, a fitting inspiration given that Waltham was headquartered just outside Boston. It is easy to imagine a watchmaker, struck by that early morning light, setting out to preserve it on a timepiece. The porcelain enamel dial features bold Roman numerals and a finely detailed minute track, with markings for each minute and inverted triangles at every 15 minute interval. The result is a layout that feels both elegant and classic, yet entirely unique with its sunrise motif. Inside is a 16 jewel Waltham movement produced between 1898 and 1915. An exposed mainspring barrel and dramatic damaskeening give the movement depth, allowing it to shift and catch light across the plates. Every component was meticulously refinished in our workshop in Little Rock, Arkansas. Screws and steel hardware were thermally blued by hand over an alcohol lamp (read more here), while the jewel settings, gear train, balance, and balance weights were individually hand polished to restore their rich golden tone. The original hands were mirror polished to remove corrosion, then thermally colored by hand, producing a deep blue that stands out clearly against the sunrise dial.

The timepiece is housed in our 40 mm surgical-grade 316L stainless steel conversion case, designed for one of the best fits available in any conversion. Engineered with both caseback and crown gaskets, it offers water resistance up to 50 meters (though it is recommended to remove the watch before water activities). Fully serviced and carefully inspected, this watch is ready for your next adventure.
