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.

Warning! Small parts.
This is one of the coolest gifts I have ever received. It does take time and careful attention to instructions . But, when completed it is accurate to a couple minutes a day, runs for about 14 hours per reset. It has been hanging in my entry for several years now. A great gift.
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
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
Please contact our cupport for help with assembling: customerservice@ugearsmodels.com
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.
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
Thank you for your review.
Please contact our support team via email for assembly help: customerservice@ugearsmodels.com.
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.
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

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.
Super
