The fabric straps are comfortable and wicks away moisture, but keeps moisture in and isn’t too formal. The silicone strap is durable and waterproof, but sweat-wicking. I have sensitive skin and have to wash the silicone strap and let my wrist breathe sometimes if I don’t want rashes. Leather, on the other hand, is durable. It is comfortable to wear and breathable, and will mold to the skin. In my opinion, it is also far more stylish and professional-looking than either fabric or silicone. Bluebonnet is a small Texas-based company that makes Apple Watch straps out of full-grain calf leather. I was very impressed with the thickness of the leather and the build quality of the Apple Watch insert and buckle (whether the metal parts are silver or stainless steel varies depending on the color of the band). It fits my 41-mm Series 7 perfectly. But if you have a small wrist, you should probably punch an extra hole or two in the band. Don’t be tempted to use a knife—either get a leather hole punch or take it to the store.★ Alternative: If you’re a baller, Apple has its own Hermès collaborations that I don’t have. However, I have played with the band Single Tour for Apple Watch at Apple Events and they are beautiful and turn the Series 10 into more than a rich watch, if you are the kind of person who cares about the ethics of the watch.Quince is a direct-to-consumer business that purports to offer luxury essentials at an affordable price. The leather on the Apple Watch strap ($30) is stiffer and thinner, the color isn’t as vibrant, and the hardware is weird—I’m not sure why the buckle has an extra loop at the top. However, it comes in two different sizes, and the smaller one fits the Watch SE. If you want a cheaper option, this will work for you.
