Using this Michele band for your Apple Watch is super easy. First, choose the right end - piece that fits your watch size (either 38/40/41mm or 42/44/45mm). Then simply attach the band to your Apple Watch. When wearing, make sure it's not too tight or too loose for your comfort. As for maintenance, you can clean it with a soft, damp cloth. Avoid using harsh chemicals as they might damage the silicone or the stainless - steel parts. Also, keep it away from extreme heat or cold to maintain its shape and color. And remember, this is just the band, so you'll need your own Apple Watch to use it.
