Antique Gruen Veri-Thin Precision 17J 14K Gold Pocket Watch SS256

This Gruen Veri-Thin Precision (SS256) is a standout piece because it represents the transition between the pocket watch era and the modern "ultra-slim" aesthetic.

The "Veri-Thin" Engineering
The name "Veri-Thin" wasn't just marketing; it was a patented mechanical layout. In traditional watches of that era, the internal wheels were stacked, making the case thick. Gruen’s engineers in Biel, Switzerland, redesigned the bridge and wheel placement so the parts sat side-by-side rather than on top of each other. This allowed for a case that was 20% to 30% thinner without compromising the accuracy of the 17-jewel movement.
