(1) new old stock BB watch crystal from my personal cabinets. MX2178-MX2349 Military(curved) Rectangular Sharp Corners. Military has a curve in one or both directions. If you want a photo of the exact crystal in the pull-down listing or to verify the length dimension in mm, let me know and I will send. All listed have labels but may be dirty but will clean bright and clear with soap and water. If you order (2) or more they will ship for the same shipping fee. All will be wrapped, placed in a new plastic protective case, and ship in a padded envelope. You will love the packaging. I have been amassing a crystal hoard over the years and I almost always have what I need. Time to share! No way I can list everything I have.
