Using your new Lagos watch bracelet is a breeze. First, make sure your Apple Watch is the right size (Series 1 through 9, 38mm - 45mm). Open the double - button box clasp and attach the bracelet to your watch. Wear it like you would any other bracelet. As for care, avoid hitting the bracelet against hard objects to prevent damage to the ceramic and steel. Clean it regularly with a soft, dry cloth to keep it looking shiny. If it gets wet, dry it immediately. And remember, the watch face is sold separately, so take good care of your own watch face too.
