The watchband seems to be well made. This watchband feels confortable on my wrist. The length is 8.75 inches or about 23cm, that's usable length for arm diameter. This band just barely fits my wrist with no slack and no space for adjustment. If you are a stout person with large wrist you might skip this product. This type of band will absorb sweat when working or exercising and more so if worn too tightly. My nylon watchbands get a bath with simple green, once a week, when worn every day. A good band for those with medium wrist sizes. All products of this type should state the length in the details.
