This is a pocket watch decorated with the wings of a genuine Morpho butterfly, a jewel of the forest. The combination of the beautiful structural color of Morpho blue and the gunmetal black pocket watch is a beautiful piece! How about a piece that allows you to enjoy the brilliance of a real Morpho butterfly anytime? To set the time, pull out the crown, adjust the hands, and then push the crown back in to start the watch. ★About the Battery★ The watch face parts of all types have a button battery inside when the back cover is removed. The corresponding batteries are SR626SW/SR66/LR626/LR66 AG4/377 any of these. We have checked the operation at the time of delivery and stored it in a state where the claws are immediately engaged to stop it. We check the operation again just before shipping after purchase, but it is a test battery. You can replace the battery yourself if you have one. #AtelierMomo #Morpho #ButterflyAccessories #PocketWatch ※The wings of the Morpho butterfly change their brilliance depending on the viewing angle, so please be aware that the impression may differ from the actual appearance in the photos.
