Easy to build and great looking

I really enjoyed building the watch with my partner. The provided instructions give you the gist of how to put it together, but as a complete watch beginner I needed a bit more guidance. I found some more detailed YouTube videos that helped us put it together and now we have a beautiful statement piece.

Gave as a gift. Friend enjoyed it and looks pretty good. Packaging and presentation could be a little nicer. It all came tossed in a bubble envelope.

Great watch

The watch is beautiful and the kit helps a lot first time builders.


Absolutely stunning dress watch


Over all I love what I got. Enjoyed the experience of putting the watch together. Don't like the strap, going to order a bracelet. Going to pick a couple more dials to see which one fits me best. Worth the money. Automatic mechanical watch for little cash.
