I also have a 6.5 inch wrist, and I think it fits perfectly on my wrist. It does have heft, but I don't find it unwieldy and the size has never felt too large for my wrist. The top of my wrist is pretty flat, so depending on the shape of your wrist you may have a different experience. As a point of reference, when sizing the factory-supplied strap I use the next-to-last notch.
