Aulumu A11 for Apple Watch Ultra 49mm Band for Men Mag Buckle Slim Band Designed | for Apple Watch Ultra 3/2/1 49mm, Series 11/10/9/8/SE2/7/6/SE/5/4[46mm/45mm/44mm]

The Aulumu A11 Mag Buckle Slim Band is easily the best Apple Watch band I’ve purchased to date. It combines a clean, minimalist aesthetic with impressive functionality, and it pairs especially well with the Apple Watch Ultra in both form and performance. From day one, it’s been lightweight, durable, and surprisingly comfortable—even during long wear periods or workouts. One of the standout features is the magnetic buckle system, which makes putting the watch on and taking it off remarkably fast and easy. The design feels intuitive and fluid, with a strong enough hold for day-to-day activity. It also looks great—subtle enough for professional settings, yet modern enough to catch the eye. If I had one small critique, it’s that the closure mechanism relies on both a light magnetic clasp and Velcro, which raises a minor long-term concern. Over time, Velcro tends to wear down, and I do wonder whether the magnetic hold alone will be sufficient years down the road. That said, this is more of a theoretical worry than a practical issue at this stage. Ultimately, this is a well-executed product that strikes the right balance between convenience, comfort, and appearance. Highly recommended for anyone looking to elevate their Apple Watch experience with a low-profile, high-functioning band.

It’s wide, nylon and has a chunky, magnetic clasp. The watch lugs are solid, literally, and it accommodates a wide range of wrist sizes on account of its use of 2 differently sized counterstraps. They are fastened via Velcro, but it’s the new, updated stuff and full length. As I have smaller wrists for my size, I appreciate the extra strap and it fits nicely once applied. It’s comfortable enough for sleeping but chunky enough to match the Ultra’s aesthetic. The magnetic clasp isn’t the strongest, and while the passive hooks do a decent job of aligning the clasp, it does nothing for security. That comes in the way of a Velcro pull-tab. It’s definitely secure; there’s no way it’ll fall off unless you forget to secure the tab, but if you forget, it’ll definitely fall off. I would’ve preferred stronger magnets, a mechanical locking clasp, or both. Otherwise, ignoring the childish graphics in rubberized print, it’s clean enough for an adult to be seen in public while wearing it. If the graphics bother you enough, you can always scrape it off. Despite being twice the price of most other straps, this one is worth the cost to me, only just.

I really liked the look and wanted it to be my all around watch band. When I go this it was packaged well. Looked great just like what I was expecting. I put it on and just loved the look and feel. The magnet connection was great the Velcro is the above the magnet to hold it secure worked. So why 2 stars? 1 for the look, I really really like this apple watch band so that 1 star. The second star is for the fit, I like how you can adjust to fit how you want your watch. Now here is where it fails. After daily use I did not realize until it was almost too late that the Velcro above the magnetic latch was just glued on! GLUED ON! While at work my watch band got caught on a fixture and my watch fell off my wrist! I was Surya’s wondered why when there was a Velcro piece holding it together. I looked and the Velcro was on where is grabs but the piece with the magnetic was flopping around! I them inspected the other Velcro part of the watch band only to see that it is all glued!!! I wanted to buy more to match this brand but now I doubt that will happen. Time to look for a replacement. *** July 2nd replacement of watch band came in! I am very happy to receive the replacement and wear this band again! Looking at it I can honestly say I can’t tell the difference with the adhesion to the defective area. I will wear as usual and update if there are any issues. So far I am very happy with the company and there efforts to correct any issues in a fast and friendly manner. Thank you for keeping a great standard with the consumer!

This was one the best Apple Watch Ultra band I used since I bought the watch a few years back. The build quality is excellent, the band weave is great, the stainless steel buckle and magnets are very good. However, the small Velcro tab that secures the buckle got detached, so the risk of the buckle opening and the watch falling off my hand became very high, I had to change the band to something else. I emailed the company through there website as soon as this happened about a month ago go but I didn’t hear from them. EDIT 1: Today I was contacted by Alumu and they confirmed that they have updated the design of the band to ensure the velcro part does not get detached. They will be sending a replacement band. To be honest support was swift in taking action, which is great. I will update this review once I get the new band.

Feel and Material: Using the A11 watch strap has been a pleasant experience. The strap is made from ultra-fine nylon yarn, which gives it a unique, velvet-like texture. This makes it incredibly soft and comfortable against the skin. When you touch it, it feels luxurious and smooth, which is a step up from other nylon straps I've tried. Ease of Use: The strap is easy to put on and take off. The fastening mechanism is intuitive, so you don't struggle with it. Adjusting the strap to fit your wrist perfectly is also simple, making it a hassle-free accessory. Special Note on Material: One thing to keep in mind is that the velvet-like surface of the strap tends to attract small dust particles due to static electricity. This means it can get dirty more quickly than other straps. However, this is a characteristic of the material, and it's a trade-off for the superior comfort and feel. Comparison with Other Straps: Compared to Apple's official double-layer nylon weave, the A11's material feels much better. It’s softer and more comfortable, making it a great choice for all-day wear. Conclusion: Overall, the A11 watch strap stands out for its comfort and luxurious feel. While it may attract dust more easily, the benefits of the ultra-fine nylon yarn and the velvet-like finish make it a worthwhile choice. If comfort is a priority for you, this strap is a great option.

I’m very happy with this watchband. It’s comfortable. It’s easy to take on and off with the magnetic/Velcro strip. I had an issue with the Velcro coming off. I was able to put it back on with some crazy glue and Aulumu replaced the band and sent me a new one.

I got an Apple Watch Ultra with the ocean band (could not stand it) and proceeded to purchase and try numerous bands to make this watch work for me. While I liked the "magnetic only" bands, it makes me nervous to have only magnets. Plus, they were not great-looking, either too narrow or too wide. Otterbox makes a nice, traditional, clasped sport band which I like. But it was traditional clasp - not magnetic. So, based on a review I saw online, I got this Aulumu as one to try. I was concerned because I though it might look crappy or not be good. When it arrived, and I installed and used it, my opinion changed. This is a really nice watch band, if you're looking for a sportier look. The magnetic clasp with the added "teeth" works great, and having the added velcro closure gives peace of mind. This thing is not going to fall off. Also having the larger strap being adjustable with velcro is great, to fine-tune the fit. It is sufficiently "wide" for an Apple watch Ultra, giving it a sufficiently aggressive, sporty look (what I was looking for). At the same time, it is not overly thick (or uncomfortably thick), and the metal clasp is unobtrusive, sitting in a nice spot on the wrist. I think I have found my daily band for this watch. The only thing I don't really like is the "urban technology" logo and design on the underside. It is not particularly attractive. It doesn't really stand out, but they could have opted for something more attractive. I'll probably be alternating between this one and the Otterbox silicone one. Gotta say this is is a sharp-looking watch band.

Cool watch band the design and buckle feel very cyberpunk. Unfortunately although it claims to fit a 42 mm Apple Watch due to the smaller size of the 42 mm series 10 the edges of the watchband connector stick past the watch body. Either they shouldn't claim that it that it with the 42 mm or they should include the correct size connectors so it doesn't stick out
