Gruen SUC C114C Watch Crystal

This is a vintage Gruen watch crystal, still in its original SUC (Standard Unbreakable Crystal) paper sleeve. It's a model C114C with a 10.8 measurement, specifically designed for Gruen timepieces. The packaging has that classic look you'd expect from old stock watch parts. It's never been used and is ready for a restoration project or to keep as a spare for a vintage collection.
