I bought this kit Rotary watch because I found it very interesting. Several people have made this Assembly and it was really cool!
The Kit comes with the plate, components including the processor, RTC, Led and battery. Also comes with wires. All you need is to set up!
Below Board detail.
There are the components. Unfortunately, There's a lot of SMDs to weld, In addition to keys.
See how it gets mounted. The box is not part of the kit.
I liked the Kit, but I haven't had time to build. Below link to the product, purchased on Banggood:
