olive green is the best color in the whole world. these are 3D printed in PETG, a high quality thermoplastic polymer. PETG is known for its excellent durability and temperature resistance -- ideal for your EDC. it's trickier and slower to print than basic PLA, but we think the juice is worth the squeeze.

I bought the green case for my Watch Ultra 2, and it is great, it has taken a watch I rarely used and found too heavy on the wrist and created a very useful too for the outdoors and every day carry. Turn all the health sensors and it lasts for days and any short outdoor trips. Thanks
I like it lots!! I now use it for my work and gym lol send me the first aerospace aluminum one you make be happy to try it out you know for nights out on the town😃
I love my MPU! Made me fall in love again with my Apple Watch, but also having it off my wrist opened up its usability, which allowed me to get deeper functionality with it.
Hoping for a V.2 that’s slightly taller, maybe like an Apple TV remote size. To counter weight it from being too heavy, maybe the bottom of the case then has room for an AirTag for the non cellular watch owners.
Awesome concept, even better execution. Print & build quality are excellent.
Simply superb. Does exactly what it needs to do and looks good doing it. Removing it is fairly easy but does take a few minutes, so you should consider this a semi-permanent case. Since that's what I wanted it is perfect for me. Just try it out!
Great product, good design and well packaged.
The first time I assembled it, I put the watch in and started screwing in the six screws, but didn’t pay close attention. It resulted in the two screws below the watch, not seating fully, and thus created a gap which allowed the watch to have some wiggle room. So I undid all six screws and rescrewed them in, left to right, top down, paying close attention to applying pressure to pinch the top and bottom has closed while I screwed in the screws. And that worked perfectly!
Very pleased with the mini phone case / concept people I meet are interested in buying one for themselves. The ideal of wearing a real watch and having a way to communicate without all the noise of the digital world is refreshing and freeing I just keep my iPhone 16 Pro Max in the bag now
Ace - would thoroughly recommend - material difference to the time on the blasted phone. Quick postage, well packaged and the stickers were appreciated too!
Absolutely top tier and exactly what I was looking for! Im so glad I found this case. Going on day 6 with minimal screen time. I feel like Ive gotten my life back.
A truly practical and beautiful product.
It would be fantastic if there was a pure black version for my black Apple Watch Ultra soon.
Love this thing! Feels good in the hand, and is very well made. Only downside is how much attention it gets :)
It has helped me not use my iphone endlessly wasting time scrolling. Highly recommend!
I really like the look and utility of it. My only wish is that there was a quick release system so I could take the Apple Watch out easier so I could still use it to work out
Love it!
I love the case. It's been my solo phone for 2-3 weeks now. The only problem I'm having is over-heating issues with the Ultra 3. When i'm using LTE talking on the phone outside, it'll shut down. Part of the problem may be venting issues with the case but the other part is the 90 degree weather. I think adding a few venting cut outs on the top and possibly the bottom of the case would help cool it down better.
Hey Kim - glad you're enjoying the case and thank you for the feedback! This is the first I've heard of the watch overheating. I will keep that in mind with design updates going forward.
I purchased both the orange and green cases. Both look great. Quality is top-notch, has a great texture, and is grippable. The included lanyard and bead are a nice touch. Fits my Apple Ultra 2 watch perfectly. Highly recommended, would buy again.
I’m loving the form factor and build quality. So much fun to use, and the design raises some eyebrows. Highly Recommend.
Overall, it is a great product. It is very sturdy and secure. I would buy it again. The only thing I would like to see is it extend beyond the face and back of the watch. If I lay it face down, it rests on the screen and it I lay it face up it rest on the sensors. It would be nice if it laid flat.
This is a great case. I love throwing this in my pocket instead of my phone. I still pull it out to check it like I would my phone and then realize I can't do anything with it and put it back in my pocket. I also love wearing traditional watches and it allows me to use the apple watch and keep my traditional watches. Great product. Great solution.
I really enjoy using this nifty little case. It adds a few seconds to transactions but that is more than made up for by the utility I find in the case. The only drawback I am experiencing so far is a bit of a lag and inconsistency with using the workout features EG The watch doesn't keep up-to-date with the stops and starts in my bike commute so the data is not very accurate.
Incredible design, great feel in the hand. This really transforms the watch into a fun gadget that feels unique different than a watch or phone in a odd way. Feels like a communication device form Star Trek - really fun.
Incredible craftsmanship, I'm getting questions and compliments every time I pull this thing out.
Amazing concept! The solution to my dumb phone problems. Well done.
When i first saw this i was intrigued. I use my watch really for a few things like setting up notes or reminders via Siri, a flashlight, a compass, listening to music, and Wallet.
This case is perfect to allow me to do these AND now i also get to wear some of my favorite watches.
I would really love to see this as a metal or aluminum case, not to take way from the beauty of the 3d printed case as it is awesome.
I love showing this thing off!!
It’s awesome. Easy to carry with the great form factor.
Awesome product! Love mine. I can actually wear my nicer watches again and not having your actual phone on you is incredibly freeing.
