A:Answer Thank you for reaching out, Johnny. We've noticed that you're interested in using this watch band with your Watch4 Classic. While Samsung watches come in different shapes and sizes, many of them have the same band width. As long as you have the correct width, you can swap out bands whenever you like. If you ever feel like changing up your look, we offer a wide range of replacement bands on our website. You can also check out our article "How to change the band on your Samsung smartwatch" to help you find the correct size for your watch. If you have any further questions, don't hesitate to reach out to us at Support. - Kelvin
