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 a 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, anywhere? (The background box is 5cm square, for size reference) The watch starts when you pull out the crown to set the hands, and then push it back in. ★About the Battery★ The watch face parts all have a button battery inside when you remove the back cover. The compatible batteries are SR626SW/SR66/LR626/LR66 AG4/377 any of these. We have checked the operation at the time of delivery and store it with the claws engaged to stop it immediately. We check the operation again just before shipping after your 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.
