Overview

There is a special place in our hearts for the honest, hardworking watches of the mid-20th century. These are the timepieces that were the backbone of the industry, the reliable and stylish companions that were worn with pride by a generation. Gruen, with its unique blend of American branding and Swiss “Precision” manufacturing, was a master of this form, and this beautiful “Autowind” model is a perfect example of their craft.

In the 1960s, the automatic, or self-winding, watch had become the new standard, and a fierce competition in quality and features emerged. One of the key battlegrounds was the jewel count of a movement. While the standard was often 17 jewels, a higher count, like the 25 jewels proudly displayed on this dial, was a clear signal to the consumer that this was a premium, high-grade caliber. The additional jewels, often used in the automatic winding mechanism, reduced friction and wear, leading to a more efficient, more durable, and longer-lasting movement. This wasn’t just a watch; it was a top-tier engine from a trusted maker.

This particular Gruen Precision Autowind is a stunningly preserved time capsule from that era. It features a gorgeous, vertically-brushed silver sunburst dial that is in simply fantastic condition. The clean, uncluttered layout is a masterclass in mid-century design, with sharp, applied dart-style hour markers and a classic dauphine handset that create a timeless and incredibly legible display. For the true vintage enthusiast, the “Ra SWISS Ra” signature at 6 o’clock is a fantastic detail, signifying the original radium lume plots and firmly dating the watch to the classic 1960s period.
