G-S Flexo MT284-25 Watch Crystal for Gruen Veri-Thin Yale

This is a vintage G-S Flexo replacement watch crystal, specifically made for the Gruen Veri-Thin 'Yale' model. It's still in its original paper envelope, which is marked with the MT284-25 part number. The crystal measures 22.0 by 16.7 mm and has that classic rectangular shape typical of mid-century Gruen watches. It's a great find if you're looking to restore an old Veri-Thin to its former glory. New old stock.
