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 silver pocket watch is a beautiful piece! How about a piece that allows you to enjoy the brilliance of a real Morpho butterfly at any time? (The background box is 5cm square, for size reference) The top is an acrylic cabochon. To set the time, pull out the crown, set the hands, and then push the crown back in to start the watch. ★About the Battery★ The watch face parts all have a button battery inside when the back cover is removed. 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 them with the hands stopped by engaging the tabs. We check the operation again just before shipping, but the battery 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 between the photos and the actual appearance.
