Replacement bands for the Samsung Galaxy Watch line. The Galaxy Watch 4, 5, 6 and 7 use a standard 20mm quick-release band, so almost any 20mm strap clicks straight on with no tools. The Galaxy Watch Ultra and, from 2025, the Galaxy Watch 8 and 8 Classic use Samsung’s own Dynamic Lug system, so those models need a band made for that connector or a dynamic-lug adapter — standard 20mm bands will not fit them directly.Match the band width to your watch and pick a size for your wrist. For picks, fit help and a full model-to-band compatibility table, see our guide to the best Samsung Galaxy Watch bands, or the best Galaxy Watch Ultra bands if you own the Ultra.
