GS Acrylic Crystal CMY350 for HAMILTON Electric - 29.7 x 27.2 mm - New

GS Acrylic Crystal CMY350 for HAMILTON Electric model wrist watch, notated by GS as 98100 / 4002 (and called Electronic), measures 29.7 x 27.2 mm, new in envelope. These are perfectly clear crystals that haven't been stored for 75+ years like other ones on eBay often are. Pretty much all GS crystals require some light filing / sanding for proper fit, as indicated on the back of the envelope. That said, I completely disagree that they require no cementing, but they require very little. Can supply just about any size Watch Crystal you need (acrylic or glass) so feel free to inquire. I specialize in hard to find watch parts and all watch parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
