SUC A165 Watch Crystal for Gruen Benrus

This is a vintage SUC watch crystal, still in its original paper packaging. It's an octagonal shape, specifically model A165, designed to fit certain Gruen and Benrus watch cases. These are great to have on hand if you're restoring a mid-century timepiece and want an authentic replacement part. It's new old stock, so it hasn't been used, though the paper envelope shows a bit of age. Made in the USA.
