    Size guide


    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.

    1. How do I know my wrist size?

    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.

    2. What is the watch band width / watch lug measurement?


    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!

    Questions? We've Got Answers! ⭐

    Real talk about your new favorite watch band

    Will this actually fit my watch?

    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.

    Are third-party Apple Watch Bands safe to use?

    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.

    What if I don’t love it?

    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.

    When will it get here?

    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.

    What makes Astra Straps different?

    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.

    Does the perforated design on the Neptuse Silicone Band actually make a difference for comfort?

    It really does. The ventilation holes let air flow directly against your skin, which prevents that sweaty, suction-cup feeling you get with solid silicone bands — especially during workouts or in warm weather. It keeps your wrist cooler and drier throughout the day, and the two-tone color contrast through the holes gives it a sporty look that solid bands can't match.

    Is the Neptuse Silicone Band a good option for someone with a very small wrist?

    Yes — the Neptuse is one of our best fits for smaller wrists. The Small–Medium size starts at just 3.54\", which accommodates wrists that most bands simply can't fit. The pin-and-tuck buckle with multiple holes lets you dial in a snug, secure fit without any excess strap flopping around.

    How does the Neptuse Silicone Band hold up with sweat and water during workouts?

    The Neptuse is built for it. The silicone material is fully water resistant, so sweat, rain, and post-workout rinses are no problem. The perforated design also promotes airflow against your skin, which helps prevent that sticky, uncomfortable feel you get with solid silicone bands during intense exercise.

    How does the Neptuse Band compare to a magnetic silicone band like the Avoco?

    The biggest difference is the closure. The Neptuse uses a traditional stainless steel pin buckle that locks into a fixed hole — it's a classic, no-nonsense fit that won't shift once it's fastened. The Avoco uses a magnetic closure for a more stepless, adjustable fit. If you prefer a secure, set-it-and-forget-it feel with a sporty buckle look, the Neptuse is your pick.
