Do you like the idea of converting your genuine Moonswatch to have a metal case? Here is the movement spacer/ring that you will need to enable the original Moonswatch movement to fit into a VK63 metal case. There are a few YouTube videos showing you how to do this, it does involve destroying the original plastic case and crystal so proceed with caution! You will need a new stem also. You can obtain the metal case and stem on eBay or other online outlets. This ring part however is not available to purchase anywhere else, to my knowledge.
Note this advert is ONLY for the conversion ring, the image of the watch is for reference only. You will receive 1x black nylon ring only.
