HISTORY & DESIGN
The history and details behind this watch.
Our TYPE A-17a Night & Day recreates the distinctive pilot’s watch described in our original account as an Elgin masterpiece used by the U.S. Army Air Forces during World War II.
The A-17a bears the last A-series designation made for U.S. military pilots. As aircraft became capable of operating by day or night, its unusual 24-hour dial distinguished daytime from nighttime with white and black halves.
We have recreated the design as a quartz watch. Coin-edge detailing on both the front and back of the case helps make scratches to the edges less conspicuous. The crystal is shaped into a rounded dome.
The dial uses a slightly creamy off-white, rather than pure white, together with black to create an antique character. The original strap choices included a two-piece dark-green cotton chino-cloth strap and a khaki nylon grosgrain alternative.
