Twist-Flex Band

Very nice looking and fit my Apple Watch perfectly.


This Twist-O-Flex band works great with the Apple Watch and is very comfortable.

Very nice watchband

I got this watch band for my Apple watch and I am very pleased. The band is well made and the price is very reasonable. I had to take it to a jeweler to get it sized. Now my Apple watch looks like an expensive timepiece. I have seen similar watchbands, also by Spiedel, on Omega watches. So I knew that I would not be disappointed.


fits perfectly, feels very comfortable

Great product

I received my new watch band yesterday and put it on today. It was very easy to install and fits and looks great! Thank you!
