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 Primus is an integrated band-and-case combo — the case comes built right in, not as a separate piece. The shock-resistant frame features 2mm raised edges around the screen for bump and scratch protection, and the whole unit snaps on as one piece for easy installation. No need to buy a case on top.
Yes — the Primus is designed with wireless charging compatibility, so you can place your watch on the charger without taking the case off. The cutouts are precisely shaped to keep all buttons and the charging contact fully accessible.
That's exactly what it's built for. The band is made from high-quality flexible silicone that stays comfortable over long hours, while the rugged matte case frame absorbs minor impacts from daily knocks. The stainless steel buckle keeps it locked in place so you're not worrying about it during physical work.
The Primus comes in three bold colors: Black, Dark Blue, and Army Green. The matte finish is part of the material itself rather than a coating, so it's designed to maintain its look through regular daily wear and activity.
