Hey there! Welcome to the Apple Watch community! Just a heads-up: the Peony Sport Band is no longer available sold at Apple Store. To find a similar strap, you might want to check out third-party sellers or authorized resellers like Best Buy or TJ Maxx for older releases. Plus, you could save some money this way! I snagged a Plum Gen 2 Sport Band for just $15. Oh, and those $12 leather bands like the Modern Buckle were fantastic too!
