G-S Flexo MY299-50 Watch Crystal for Gruen

This is a vintage G-S Flexo watch crystal, specifically made for a Gruen timepiece. It's still in its original paper envelope, which has kept it protected over the years. The crystal measures 22.4 by 19.6 mm and features that classic tonneau shape you'd expect from a mid-century watch. It's a great find if you're looking to restore an old Gruen to its former glory with an authentic period-correct part. New old stock.
