In the mid-20th century, Gruen, like many other firms, navigated a complex global landscape of trade and manufacturing. For a time, this led them to produce watches in France, leveraging the country’s skilled watchmakers to create pieces for the European and American markets. This watch is a fantastic product of that era, marked “France” at the base of its dial and powered by the robust, French-made Caliber 515SS. The “Precision” moniker, coupled with a sturdy, screw-down caseback proclaiming its water-resistant, shock-resistant, and anti-magnetic properties, tells you this was built not as a piece of jewelry, but as a reliable, everyday tool.
This specific example is a true gem for the enthusiast who appreciates character. The dial features a highly legible, military-inspired layout with bold Arabic numerals at 12, 3, and 6 o’clock. The sharp, dauphine handset was originally filled with radium lume, a detail that has contributed to the watch’s incredible aging process over the past sixty-plus years.
