Note: This is not the original Samsung strap the watch came with, but is extremely similar.

It is a used silicone for Samsung Galaxy Watch 6/5/4 44mm 40mm Pro 45mm Sport 20mm Watchband Bracelet Galaxy Watch6 43mm 47mm (Sapphire). Quick Release strap with 20mm lug.

It was a little too long for my small wrist so I'm selling it. Shorter part with the buckle enclosure is 84mm. Longer part is 125mm.
