Purchased this kit for my 89 year old dad for something to do. When he opened it, he commented that there were not any instructions and he felt it was intimidating. When we sat down together to work on it, we looked at the instructions, which were just pictures, and got started. He was surprised there was no glue to use. Once we had a few pieces together my dad's interest perked up and then it became a challenge to work on it and get it done. It took us about 3 hours. He was proud of how the clock looked when it was done and showed it off.
