The wooden mechanical transmission model is not only a toy, but also uses a special process. There is no need for glue, nails and tools when assembling, making the assembly model a smart and interesting process.
A full steam punk-style calendar: There is a planetary wheel inside, align the year with the corresponding month, and you can query any day from 2017 to 2044.
There are planetary gears and rotating gears inside to find the correspondence between the date and the day of the week. The appearance is novel, fun and practical.
