I received a model Da Vinci Clock. I've always admired these types of creations at the hobby store but I've never had the guts to pick one up. I'm glad my Secret Santa sent me one; it was a blast to put together, but the challenge is only halfway through! Even though the clock is analog, half the challenge is getting it calibrated correctly (coin weights go in the bucket on the left side, and the grey colored balls at the top are adjustable for timing) - I'm determined to get it as closely calibrated as possible, and a lot of fine tuning will be required. This is quite an interesting gift and even after assembly will continue to provide a challenge and lots of fun! Plus it makes a great decoration for my office!
