Samsung Galaxy Watch 9 40mm Watch Straps & Bands

Replacement straps and bands for the Samsung Galaxy Watch 9 40mm. The Galaxy Watch 9 uses the same Dynamic Lug system as the Galaxy Watch 8, so all Watch 8 straps and adapters fit perfectly.

Not sure which size you have? Check the back of your watch case, or on your phone open Settings > About phone / About watch > Model number - it will show 40mm, 44mm, or Classic 46mm. These sizes are fitted and are not interchangeable - a strap made for one size will not fit another.
