With all these newfangled smartwatches coming out, perhaps it’s time to get back to the basics. The sundial watch is the original smartwatch, with location specific design that utilizes the power of the sun to tell time. No batteries, no apps, no accelerometer, just classic design. Used for millennia, the sundial is the tried and true way to tell time, connecting you to the natural cycles of the sun. Your Sundial Watch will never run out of batteries or need a recharge, but cloudy days could pose a problem.

The 3D printed Sundial Watch Collection combines the latest in digital fabrication technology with ancient knowledge of the sun’s movement. The Sundial Watch allows you to escape “digital time” and the anxiety created by the constant seconds ticking away your day. The Sundial Watch focuses your attention on light and shadow, developing a relationship with the sun and a more fluid perception of time.

The Sundial Watch Collection includes four designs personalized for your location and lifestyle. Each Sundial Watch is made specific to your geographic coordinates, adjusting the gnomon and angle of the hours. Using a resin-based Objet 3D printer, each watch is crafted with digital precision and made from a fused combination of a flexible material in the watchband and hard material for the watch body. All watches contain a compass inlay to orient north and keep you moving in the right direction.

Step 1: The Sundial Watch Video

<p>Finally I have a 3d Printer (UP Mini) and just printed the &quot;Classic&quot; out of ABS. Quite like how it came out, just the resolution of my printer does not seem to be perfect for this project but it is ok for me. I would be very interested in the &quot;adventurer&quot; or the &quot;traveler&quot; but is there also a way to make it fit the same compass which fits in the &quot;Classic&quot; ? Have you maybe already modeled that?</p>
<p>I would love to make this! The only problem, I don't have a 3D printer. :(</p>
<p>Same here bro.</p>
<p>Great idea, and thanks for sharing the designs. Worth mentioning, this won't work with bright moonlight (as suggested in step 10), for obvious reasons...</p>
<p>How did you print the numbers to go on the watch face? They seem to be two separate files rather than 1. Also I soooo vote for a version that has the pointer able to fold sideways so it is not sticking up until you need it to, but isnt a totally seperate piece that you have to stick in. Love these!</p>
<p>Great....</p><p>Really it is a orignal smartwatch....</p><p>I like &quot;The Traveler&quot;</p>
I have a doubt! If you live in the South Hemisphere, how do you have to proceed! Either to build or to read hours?
<p>A sundial at a particular <a href="http://en.wikipedia.org/wiki/Earth#Orbit_and_rotation" rel="nofollow" style="">latitude</a> in one <a href="http://en.wikipedia.org/wiki/Sphere" rel="nofollow" style="">hemisphere</a> must be reversed for use at the opposite latitude in the other hemisphere. Check out the link in Step 3 under &quot;History and Description&quot; for details.</p>
Just to know, it have a Network of specialized technical assistance around the world? And how many embedded functions it have. It glows in the dark automatically or I have to push a button? <br>I think I want all of it!
<p>I WANT ONE! (The Traveler would be nice) Christmas is coming, and this would be a terrific gift for us old fogies who feel a little behind in the tech world. Do you get a commission or something if I would take your downloaded file to an outside printing source? I mean, I appreciate reading instructable files even if I probably would never make one, but many of these ideas are potentially commercial products and you should benefit from your intellectual property. </p>
<p>This is free to share and modify. It's part of the <a rel="nofollow">Creative Commons</a> as are many of the wonderful Instructables. So, please do download and print your own and join the Sundial Watch Community!</p>
<p>This is asking for OpenJSCAD web app with location detection to produce downloadable models!</p>
<p>Very, very cool project:)<br>Can you tell me what the dimensions of the smallest and the biggest model are?<br>I am currently building the &quot;60$ Ewaste 3D Printer&quot; which is also an instructable on this site. Only it has dimension restrictions of 4x4x2cm... Would that be enough for one of the models? This smartwatch would make an awesome first print project for the ewaste printer:-) Possibly I could also scale everything down a little bit..</p>
<p>Hey Thanks. The Ewaste 3D Printer looks amazing. It would be awesome if you printed a Sundial Watch. I recommend printing &quot;The Classic&quot; since it has the simplest geometry and you can add a separate watch band. The dimensions are bigger than 4x4cm, so I scaled it and added an .stl file called &quot;SundialWatch_Classic_Modified&quot; that you can use. Of course, you will want to create your own Sundial Watch top eventually to get a location specific design. Let me know how it works out. </p>
<p>Thanks a lot for adding the modified version!</p><p>I will post how it came out as soon as I will be able to do it!</p>
<p>Input your zip code or lat / long to get your exact magnetic declination at </p><p><a href="http://www.ngdc.noaa.gov/geomag-web/" rel="nofollow">http://www.ngdc.noaa.gov/geomag-web/ </a> </p><p>I have no printer, but I'm going to try to make one from walnut and a nice old watch strap.</p>
<p>Hi gkapriel, this is not only a very well done 3D printed item but just as much a perfect video presentation - so perfect it makes you want to order one on the spot... Apropos: I don't have a 3D printer and I am not likely ever to own one (I am 69). So I wanto ask: Do you know of any one who is going to make series of these watches for sale? Thanks for listening / reading.</p>
<p>There are several online services that will do exactly that. You upload the file, select materials, colors, etc., and they 3d print and send you the parts to assemble. Search for 3d printing services. Or checkout Ponoko here: https://www.ponoko.com/</p>
So smart idea! Thanks for shearing :)
<p>Thanks for the comments everyone. I'd love to hear if anyone 3D prints a Sundial Watch or makes their own design. I would have liked to make a Spherical Sundial if I had more time. </p>
Outstanding and very well written project! Bonus points for &quot;daylight saving time&quot;. Love the historical precedent! My only suggested change is to add a &quot;t&quot; (Flintstones). Thanks for sharing!
<p>Good catch. Thanks!</p>
<p>Fantastic project! Where did you get your small compasses?</p>
<p>I ordered them online from Stanley London.</p><p><a href="http://www.stanleylondon.com/smcomp.htm" rel="nofollow">http://www.stanleylondon.com/smcomp.htm</a></p><p>Thanks for your comment!</p>
<p>Very cool!!!</p>
It is a really cool sundial and I would really like to make one of my own!!!!!!
<p>And it's EMP-proof, too! It's the watch of choice for the most stylish apocalypse survivors.</p>
<p>xD Second that ! nice job :D</p>
Old school and low tech, but still super cool!
I love this!! I'm SOO glad I have a 3d printer!
<p>whoaaa</p>
<p>That looks very fun to wear, probably get a lot of questions, and it looks fairly effective!</p>
