Ronda - Set of 3 stems for Essor (Court) caliber E45 - new in packaging

Ronda No. 564 - Set of 3 stems for Essor (Cortébert) 10½ ligne caliber E45 and likely E46 as well, new in sealed packaging. I specialize in hard to find watch parts and all watch parts are unconditionally guaranteed. If you need a part for a Swiss watch I likely have it so feel free to inquire. Images do an adequate job of representing the item.
