Powered by gravity through a weighted sandbag, it uses a unique counterclockwise rotating disc system and an adjustable pendulum for accurate timekeeping. Its standout feature is a charming hot air balloon 'cuckoo' that descends hourly, making it both a captivating kinetic sculpture and a precise timepiece. Designed for adults and advanced builders, this 11-hour assembly project doubles as a striking dΓ©cor piece and an educational journey into classic clock mechanics. ## Description Product Description Ready to make your own clock? The time has come. For years, we've been hearing the same question again and again from our loyal customers: "Can UGEARS create a working wall clock with a pendulum that keeps accurate time?" We are proud to present the Aero Clock, a one-of-a-kind mechanical model and fully functioning DIY gear clock. Complexity combined with elegance Wooden wall clock puzzle 3d As you build the Aero Clock, a wooden wall clock with pendulum, you will learn the basic principles behind clockworks, how the steadying influence of a swinging pendulum operates through a rocking anchor, locking and unlocking the gears on an escapement one second at a time, thereby regulating the (slow) descent of a weight as it drives both power gears and timekeeping gears. The Aero Clock is one of the most sophisticated and ingenious model making kits. The assembled wooden clock kit is driven by the force of gravity pulling on a bag you fill with sand or salt. Raise the bag on its pulleys to wind the 3D wall clock. As the weight slowly descends, it rotates a drive gear that rotates an escape wheel through a reducer. Model size: 29.5*18.5*6.5 in Maximum size of the model: 86.6*18.5*6.5 in Package size: 14.9*6.7*2 in Number of components: 320 Estimated time of assembly: 11 hours Level: Advanced Special features On our Aero Clock, time is not marked by hands moving over a clock face. Instead, a fixed pointer indicates the time on the numbered hour and minute discs that slowly rotate counterclockwise. We've replaced the classic cuckoo with a hot air balloon that descends rapidly when the hour strikes then slowly rises again for the next 60 minutes. Memorable experience Like other UGEARS crafts for adults hobby kits, Aero Clock offers the great satisfaction of building an actual functioning timepiece that is both gorgeous and precise. This is a perfect family project or a solo construction kit and a memorable 11-hour adventure. Dedicated to discovery UGEARS wooden clock kits for adults celebrate the crucial role of clocks in accurately determining longitude so early explorers could determine precisely where they were and could then travel there again. Aero Clock wooden puzzle pays tribute to these brave adventurers. Get your Aero Clock wooden puzzle set now and discover the magic of accurate timepieces. Review: Exceptional - I don't do reviews, but in the case of the Ugears aero clock I just had to make an exception. The design and construction of this kit is definitely on another level. You get what you pay for in life. The build quality is of this kit is at the highest level. All I would say to would be buyers is take your time. Yes you could probably have it all together in a far less time than the 11 hours indicated by Ugears, but the result would certainly not be a working clock. Care and attention to detail are required. Sand all rough edges and pay particular attention to those parts with mating surfaces. Anything that rubs against or contacts with another part benefits from more attention when sanding and waxing. The smoother the better. The instructions are excellent, but in my case I had some difficulty in understanding the cord winding. Youtube did however quickly solve my problem. The end result is fantastic. Visually a work of art. A work of art that actually keeps good time and a pleasure to watch as the hour sees the balloon quickly descend from its slow rise over the hour. Personally I would not consider this kit as complex. Not for a child that wants quick results, more suited to teenagers and budding teenage adults who want to spend time creating something to be proud of. If you take your time and follow the instructions carefully you will love what Ugears have helped you create. Looking foward to my next Ugears kit. Have made many hints to Santa Review: Great fun kit! - Great kit. Went together well. The balloon was fiddly, but all in all, great fun. And it all worked! The balloon rises, then falls on the hour. It kept stopping and eventually traced it to one of the mounting screws that wasn't fully screwed in, so it twisted the whole clock slightly. Found that 2kg of sand totally filled the weight bag. (dried it well before weighing). The minute indicator has to be turned about 7 minutes cw before the ratchet kicks it when adjusting. The pendulum "weights" could do with finer adjustments to achieve more accurate time keeping, but I'm just happy it all works 😁 ## Features - Warning:Not suitable for children under 14 years.

The counter weight and the balloon both move in the same direction on mine.** A: The cord to the counter weight is rapped the opposite way to the cord going to the ballon, as one winds up the other winds out (balloon goes up, weights go down) **Q: On page 6 of the manual, does the wax cord, that winds around the round piece of wood, have to be cut to size?** A: Yes **Q: Does the clock run continuously once started or only for a limited period?** A: I think if it ran continuosly, it would disobey the laws of thermodynamics, so..unfortunately...no. **Q: What is the length of the clock, including the weught at its lowest point?** A: length 136cm wide 38cm this clock needs your full attention keep eyes on the line up dots and hang dead level or it will not work ## Customer Reviews ### ⭐⭐⭐⭐⭐ Exceptional *by D***. on 14 December 2022* I don't do reviews, but in the case of the Ugears aero clock I just had to make an exception.

The instructions are good but some sections are a bit difficult to understand. The laser cutting of the parts is incredible. I do have a working clock after quite a lot of fettling and adjustment, however despite many attempts I could not get the balloon to rise and fall. Whenever the wheel and cog for the balloon was added the clock stopped. At the moment I am happy enough with the clock and might try to get the balloon working later ## Frequently Bought Together - UGEARS Wooden 3D Puzzles for Adults Aero Clock - Mechanical Puzzles for Adults, Wall 3D Clock Puzzle with Pendulum Model Kit - DIY Miniature Kit Crafts Gift for Fathers Day - 320 Pcs - UGEARS Wooden 3D Puzzles for Adults - Astronomer Table Clock with Tourbillon Model Kit - Mechanical Clock Kit Functional DIY Miniature Kit Wood Crafts for Adults - Gifts For Puzzle Lovers - 338 Pieces - UGEARS Mechanical Tellurion 3D Puzzle Planetarium Solar System Model Kit for Self-Assembly Idea Earth and Moon Jigsaw 3D Wooden Puzzles for Adults Rotating Astronomy --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.de/products/329174049-aero-clock](https://www.desertcart.de/products/329174049-aero-clock) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-06-24*
