Loose Link Pins on the Huawei Watch (hwatch) Band
You're probably here because you've tried to remove links from your new Huawei Watch and found that the pins slide back into place with no resistance and fall right out. It turns out that's because Huawei used a pin and collar link as opposed to a cotter pin. Without the collar, the pin will slide right through the link.
