The media could not be loaded. I enjoyed this kit. I have spent a little time afterwards to reverse engineer the design and that was both fun (for me) and educational. One of the complaints I read upfront was that the documentation is mostly all pictures. That's what we get when people start complaining about things not being in their language. If you get this wonderful clock I have a few pointers.* There are 4 boards from which you remove the individual numbered parts. The parts themselves are not numbered. The number is beside the part and remains with the board. So do not remove parts until you need them or otherwise write the part number on the part. You might spend a lot of time comparing pieces to their pictures. With my kit some were already loose from their board and presented a bit of a challenge in keeping them straight.* One of the part boards has holes to help you locate the screws for mounting the clock on the wall. So do not discard those boards prematurely. It will help to use a level on the board too when marking the screw positions. That isn't mentioned. The clock has a provision for leveling. It does need to be level. The 'tick' and 'tock' need to be evenly spaced in time for the escapement to work efficiently.* With each major step you put together a sub-assembly such as one of the several gear pairs with axle. Label the assembly before you set it aside with the range of part numbers used in it. Later in the instructions they show you where to install the sub-assembly and you will have fun trying to figure out which is which unless you tag them.* There are errors in the instructions so be careful to match the parts with the pictures. There were but a couple of errors and they were obvious. Like for instance noting the wrong range of parts for one of the sub-assemblies.* A weight powers the clock and friction works against you. Wood is porous and wood rubbing against wood creates a lot of friction. You are instructed to rub various areas of the gears and axles with (cold) wax. This fills the surfaces of the wood and greatly reduces the friction. Do not leave wax chunks or excess residue on the parts. This is an important step. You don't want to later disassemble the clock (which you can do) to have to lubricate critical areas.* Once you are ready to go be prepared to add a little more weight than recommended to get things running. The clock will not at first run for very long before stopping. Make sure that each gear lines up with the adjacent gears appropriately and that no parts are contacting the frame where they shouldn't. Make sure the clock is level. Once you get it to run for an hour or so back off on the weight. Once broken-in the clock will run nicely on the recommended 0.55 kg weight. I will even try less as things progress.* There are 3 clutches in the design. One beefy arrangement allows the weight to be raised for rewinding. Two more subtle clutches free the minute and hour hands so they can be set using a clockwise motion. These are interesting. There is also a thumbscrew thing that helps in leveling the clock. That is a nice feature.* You can decide whether the clock is running slow or fast. If it is running fast lower the weight on the pendulum. Use your stopwatch app and time 100 swings of the pendulum. That should be just a small fraction over 132 seconds. Yes, I figured all of the gear ratios. The weight drops about 4-1/4 inches per hour and (provided you mount it high enough on the wall) the clock will run for 12 hours from fully wound.* You will need a beer/pop (soda) can to fill with sand for the weight. It is not visible (but could be). Um, I used an empty 60 Minute IPA just in keeping with the time motif. An additional ongoing source of empty cans can be helpful during the testing phase.

Be prepared, I needed needle nose pliers, flat head small tip, and a big tablet. Warning some parts are loose and will fly out. Lol still working on it as 7 hours came and when, I still have an hour to get it right.

This was my first 3D puzzle and it was a very fun project. I read all the reviews before ordering and it helped with needed advice to speed construction and avoid some mistakes. Initially my clock would only run a few minutes and I had to lightly re-sand some gear teeth and re-wax. It has been running for 3 days now with a little more than the recommended weight and keeping pretty accurate time. I have thoroughly enjoyed the time I have spent constructing this clock and plan to build the UGEARS Aero Clock next. I highly recommend this puzzle.

The model had all its pieces, and assembly was pretty straightforward. Unfortunately after several attempts and rebuilds this model has just way too much torque/spacing on the gears. The only way I could get it to run was with 5lb of weight, even then it would only run 2o minutes. There’s another pendulum clock by ugears “Aero” that I’d recommend instead.

Great Challenge to build but I cannot get the clock to work??Might have to re wax the running parts.

Horrible product with terrible tolerances and even more poor quality. They expect you to cram a dowel into a hole that's the exact same size or smaller. No extra pieces btw. It came with a nice little note that pretty much says "WAIT!!! before you buy, please know, this is wall art. This is NOT a functional time keeping device. It's a scam. DO NOT BUY THIS PRODUCT.

The media could not be loaded. Bought this for my 8yo son for Christmas to work on together. Took us about two months of occasionally working on it, but we did it! He would figure out what needed to happen, pull the parts, try to fit them together, and then I'd help with the force sometimes needed to get the parts to "click" (and QC his work!). But in the end... It's working! And we both love it! Took a little more weight in the ballast than the plans call for, and (pro tip) make sure to REALLY clean out the little wood nubs left within the gears from where they attached to the wood sheets... But this clock has been running for close to a week now. Finally have the pendulum dialed in to keep nearly perfect time! It's awesome, and he is so proud of it!

This is a thinly laminated "plywood". Pieces separated from main panels. Clearly numbered, one must exercise caution with proper orientation of particular pieces. Many pieces were undersized, therefore fit incorrectly. It's a beautiful ART PIECE.A nightmare to construct. Patience is mandatory. Worthless as a "time piece" when pieces don't fit properly. Definitely not for children.
