*【Compatible Models】Our magnetic silicone band features a universal 18mm 20mm 22mm lug width, making it compatible with a wide range of smartwatches and traditional watches that use 18mm 20mm 22mm straps — including Huawei Watch GT series, Honor Watch series, Amazfit, Garmin, Fossil, and many more. Please confirm your watch's lug width (18mm 20mm 22mm) before ordering to ensure a perfect fit. *【Magnetic Buckle Design】Featuring an innovative magnetic clasp system, this band offers effortless one-handed adjustment and a secure, rattle-free fit. The strong built-in magnets hold the band firmly in place — no more fumbling with traditional buckles or pins. Simply wrap, overlap, and let the magnets do the work. *【Premium Silicone Material】Crafted from high-quality, skin-friendly silicone, our band is soft, breathable, lightweight, waterproof, and sweat-resistant. Whether you're running, swimming, working out, or sleeping, it provides all-day comfort without skin irritation — a durable and affordable upgrade for your watch. *【Stepless Adjustment for Perfect Fit】Unlike traditional hole-based straps, the magnetic closure allows for stepless (infinite) adjustment — you can fine-tune the fit to exactly your wrist size, down to the millimeter. Fits most wrist sizes (approximately 5.5"–8.3" / 140mm–210mm) — perfect for both men and women. *【Secure Magnetic Hold】The powerful magnet provides a secure hold that stays in place throughout your daily activities, workouts, and even sleep. Easy to adjust with one hand, yet stays locked until you intentionally slide it open. Please note: The magnetic closure is designed for daily wear and light to moderate activity — not recommended for intense swimming or high-impact sports.
