This movement was originally manufactured in 1948 by the Hamilton Watch Company to Ball Watch Company specifications. The 999B uses Hamilton's revolutionary Elinvar Extra hairspring and monometallic balance, utilizing the best technology of the time to create an ultra reliable, beautiful, high-end watch for railroad conductors.
This excellent condition piece features beautifully decorated, finely beveled 3/4 style nickel plated bridges with circular Geneva stripes, 21 precision cut jewels, a Hamilton whipspring regulator, adjustment to 6 positions, and adjustment for temperature.
The blued steel, extra heavy, whipped spade style hands point to bright, bold, 'boxcar' style sans-serif Arabic numerals on the excellent condition, original enamel dial. This movement is one of 27,000 made.
