At Astra Straps, all our bands have clear and specific sizes indicated. Please check the sizing guide below before ordering. If you are still unsure, you may contact us here.
Simply use a flexible measuring tape to wrap around your wrist and record the measurement on the tape that overlaps the zero end of the tape OR just grab any string/paper strips to do the same, then lay the string on a ruler to get your accurate wrist size.
In most cases, knowing your wrist size/length will be sufficient. Check your wrist size against the size of the strap that you wish to purchase on the individual product details page.
From there, you can select and purchase our watch straps: Small (S), Large (L) or Free Size.


In certain cases, knowing your wrist size alone may not be sufficient. In such a scenario, you will need the watches' band width size, also know as the watch lug width size.
Your Apple watch will say the measurement on the back.

If you cant find the size on the back place the watch with the watch face facing up. Take the measurement of the distance between the lugs (where the watch strap fits).
For Apple Watches the you have the choice between 38MM, 40MM, 41MM, 42MM, 44MM, 45MM & 49MM, you can also enter your watch model number into a search engine to find what size your watch uses.
Apple Watch 7, 8, and 9: The Apple Watch Series 7, 8, and the newly released Series 9 are compatible with a wide range of our bands, including sizes 38MM, 40MM, 41MM, 42MM, 44MM, 45MM, and 49MM. For watch cases, they fit the 41MM and 45MM sizes.
Apple Watch Ultra and Ultra 2: The recently introduced Apple Watch Ultra and Ultra 2 are compatible with 45MM and 49MM bands. As for the watch cases, both the Ultra and Ultra 2 models are available in a 49MM size.
Using these three measurements, you are now ready to grab your band!
Absolutely! Whether you’re rocking the original Series 1 or the latest model, we’ve got you covered. Just check the size on the back of your watch (if you're not sure), and we'll handle the rest. It’s that easy.
Yes. All Astra Straps bands use use precision-machined stainless steel connectors that lock securely into your Apple Watch — the same mechanism Apple uses. They won't scratch your watch or interfere with sensors like heart rate or blood oxygen. All our materials are skin-safe and nickel-free, and using a third-party band does not void your Apple Watch warranty.
We get it – sometimes things just don’t work out. If you’re not in love within 100 days, send it back, no questions asked. We’ll refund you, no drama. We want you to have a band you absolutely love.
We’re all about speed. Most orders ship within 1-2 days, and you can expect it to arrive shortly after.
Plus, if you spend over $50, shipping is on us. Because let’s be real, no one wants to pay extra for shipping.
Great question! At Astra Straps, we don’t just make bands – we craft them.
Every single band is hand-finished to ensure the highest quality and attention to detail. We’re all about combining top-notch materials with unique designs that reflect your personal style.
Plus, we test every band for comfort and durability, so you can count on a strap that’s as strong as it is stylish. When you choose Astra Straps, you’re not just getting a band – you’re getting a piece of wearable art.
The Inflexus uses a blend of polyester yarn and silicone threads, which gives it more stretch recovery and durability than standard nylon braids. It also features a carbon buckle detail for fine-tuning the fit, so unlike a true solo loop, you're not locked into one fixed size. With 30 color options, it's one of the most versatile braided bands in the lineup.
No — the elastic braided nylon is engineered to snap back into shape after stretching, so it holds its fit day after day. The silicone threads woven into the construction add resilience that pure nylon bands often lack. The carbon buckle also lets you tighten things up if you ever want a snugger feel.
It's one of the most comfortable bands for round-the-clock wear. The soft, textured nylon is breathable and never digs into your skin, even after hours of use. The slim, buckle-free design means there's nothing bulky pressing into your wrist while you sleep — most people forget they're wearing it.
Yes to both. The Inflexus is sweat and water resistant, so it handles workouts, rain, and quick showers without any issues. The braided nylon dries fast and won't hold onto odor, making it a solid choice if you want one band that covers the gym, the office, and everything in between.

Astra offers many options of bands, material and colors.
I ride mountain bikes nearly daily and ski a lot too. This band put up with 1 year and 4 months of abuse before finally breaking at the buckle. I move the adjustment quite a bit especially for skiing so that I can slide the watch further up, out of the way, for my gloves to fit. I'm impressed with how long this has held up as my only watch band. The large weave breathes quite well, it never got itchy when soaked with water, mud, sweat. I also never washed it and it stayed relatively clean looking. All in all I'd buy It again but I just saw the Moneo with it's metal snap type buckle and I want to give that one a try.
Band came on time and looks and feels exactly as described. My son really likes it. It’s breathable and he no longer gets a rash under the band.
Been looking for a strap that stays put during my runs. Love how easy it is to adjust. The colors are awesome. I would definitely purchase again!
This strap is doing exactly what I expected. The stretchy nature of the strap allows for it to keep my watch in place while I ride my mountain bike. metal and silicone straps can't do this as they're aren't able to stretch and acommodate a constantly flexing and relaxing forearm. inevitably the watch would slide down to my hand and create a pinch point at the back of my wrist. I'd have to stop and readjust. So far so good with the Astra strap.
Love my new straps (variety of colors)
I love this style of watch band. Its great that you can adjust it. This fits well and is very comfortable to wear.
This looks really nice and seems durable.
I like this band. Im always between sizes on the holes in the other wristbands. This is very comfortable. Easy to adjust and loosen when you want to take it off.
Im happy with this watch band. I've been breaking out in a rash from my silicone watch bands, so I decided to switch to this material. I love it. Its very comfy and cute. Good value.
I got this so I could wear my watch on my ankles for the treadmill - works great! I wear it on my wrist too, and its become my main band.
These adjustable bands are excellent! My son has benefited from these, as the ones that his Apple Watch came with were irritating his skin. I love that these can be washed easily and switched out and are very adjustable.
