Aero Clock. Wall clock with pendulum
Assemble me. Catch the star moment!
Ugears is proud to present the Aero Clock, a fully functioning wall clock with a pendulum that you can build yourself, mount to a wall, wind up, then watch as the seconds, minutes, and hours tick by. The theme of the Aero Clock is early aeronautics. The casing and intriguing wooden clock mechanism represent an air base located among the clouds, where zephyrs blow and filtered rays of sunlight dapple the machinery, while you, in the role of aeronaut, launch a new voyage of exploration on the hour.

This simple-yet-elegant Ugears clock is driven by the force of gravity pulling down a weighted bag (you can fill the bag with sand or salt). Raise the bag on its pulleys to wind the clock. As the weight slowly descends, it rotates a drive gear, which then rotates an escape wheel through a reducer. The clock features an adjustable weighted pendulum which interacts with the escape wheel through the steady tick-tock of the anchor mechanism. You can adjust the clock's ticking action to the second, by sliding the pendulum's top and bottom weights. The reducer also transmits rotation to an hour disc and a minute disc. The suspended balloon rapidly descends when the hour strikes, then slowly rises again over the course of the next hour.
Aero Clock features:
- Functional mechanical wall clock with pendulum
- Driven by the force of gravity (pulling down a weighted bag)
- Fixed pointer indicates time on the slowly rotating discs
- Clock discs rotate counterclockwise
- Hot air balloon acts as a “cuckoo”
- Represents an air base located among the clouds
DIY wooden clock features:
- Pre-laser-cut parts on wooden boards
- Assembles without glue or tools
- Step-by-step instructions in 11 languages
- Ready to paint (paint is not included)

Haven't got it working yet. My a2 part on page 10 is only going one direction. It's like its stuck on something and I can't figure out what. I also broke my release lever, so I don't know maybe that's part of my issue. Hoping I can get the a2 part working as it's not a clock without it moving.Any suggestions would be appreciated.
Hey there
Thank you for your feedback

Always a real pleasure to solve these puzzles, the last one :the clock and in addition it really works.
This is a second Aero Clock that we have put together.
It worked as soon as we put the weight on it. We are monitoring the clock to get the time adjustment just right. It was assembled over a leisurely 6-day period with an about an hour or two per day. It is working perfectly with the balloon dropping each hour. The instructions are very clear, but you need to proceed carefully so everything goes together as instructed. We are very happy with the clock with the gentle tic-tock.
I love my UGears clock. It is a different experience every day. So enjoyable. I will send more pictures. Thank you. Kerry
Very beautiful clock, this is a right mechanical movement and can see the gears moving and the hot air baloon going up slowly and down every hours running.
Need a more experience and patient to assembly because it may not work for the 1st time to run this clock, I was take almost 8 month to adjustment to make this clock running well. Now my clock is fully run everyday. I can say this is very great! I am enjoy to look it running and the sound like tik tok... Joy and happy.
Challenging build quality product practical time piece for the future
This was given to my husband as a gift; he loved it! He found building the clock interesting and challenging, and he is now enjoying balancing the clock to work optimally
Great product but the directions were difficult to follow at times and as a result I wound the main cord incorrectly apparently so the clock only runs for about 15 seconds and I don't have the heart to disassemble it.
Je n’ai pas encore eu le temps de construire cette maquette : je suis impatient de le faire.
Lo he montado a ratos y me ha durado dos semanas. Se puso en marcha a la primera, me costo ajustarlo,sobre todo el la bajada y subida del globo.
El manual o instrucciones de montaje hay que tener mucha imaginación para ve algunos de los dibujos y compranderlos, pero no es dificil su montaje.
Item was 2 weeks late due to customs hold lacking proper documentation. Instructions for device were at times, confusing. Metal axles for cog wheels would not stay in place. Improper spacings between wheels. Unit will not operate without stopping inadvertently. Shipping box looked smashed, perhaps making several items inside misshaped. Not a great experience for a first time customer.
Dear Horald

Super
fun to build it work as clock i like it it’s beautiful
it was a gift from my son for may birthday. i have sucessfully built this clock, and after a long time to adjust the mechanism, it was functionnal for about six months with a weight of 2kgs.
And then it did'nt work any more, and the main gear (motor) was damaged.....
i was very sad....
Though I'm still in the finishing process of putting together this model (I have to setup something to hang it on to finish!), the assembly and challenge has been great! I look forward to finishing up soon-and everything does work!
A great challenge. Had one part break but managed to repair it. Working on getting it running.
Livraison très rapide. Livreur agréable. On attend Noël pour ouvrir le paquet
Trés jolie
Hello
A lovely craft project.
Very precisely crafted components that require some thought from time to time.
I'm busy; my hands are occupied.
Thank you
Sincerely,
Peter Hübner
Great
.
Really fun to do but you need to be careful because some of the parts can be delicate due to the nature of the wood. Just make sure you’ve followed the instructions correctly before to push the parts together and don’t rush.
It looks amazing when it’s finished, I’m really impressed with the kit. I’ll probably come back for more kits.
Have not started the build yet, next in the queue but examined all of the parts /sheets and gone through the instructions and am very pleased with the attention to detail- this is my first U Gears but read the reviews and always wanted to build a clock!
Ottima la spedizione. Il regalo è stato molto gradito.
Fun Build.
Easy to assemble
Great to build these with the grandchildren
notice de montage pas assez explicite
Great kit, taking my time to build it and enjoy the experience.
Looking forward to when it is completed and then ordering the next kit.
