Also, even a real watch can't buy accessories that are not within the range of your watch style. In other words, if all styles of your watch have no belt buckle but only a butterfly buckle with belt buckle, then you can only buy a butterfly buckle, not a button that is not in the style.
One more thing to remind you, if you bring buttons, the belt you bring must be genuine, and the fake belt will not provide you with services.
Last but not least, the butterfly clasp is close to 2000.
