G-S MX334-25 Watch Crystal for Gruen Veri-Thin Marcus/Whitebell

This is a vintage G-S watch crystal specifically for Gruen Veri-Thin models like the Marcus or Whitebell. It's still in its original paper sleeve, which is a nice find for anyone doing a restoration. The dimensions are 22.0 x 18.2 mm. It's old stock but looks to be in great shape for its age. Perfect if you're trying to get an old Gruen back to its original look.
