What it is not

I designed, machined, assembled and wore this watch. It works. But it has not been through the validation of a real product, and it's not even close to the level of a "real" watch you'd buy in a boutique. There are compromises and mistakes – likely more than I've found.

Good starting point. Not a design to hand a supplier and try to sell as a luxury watch.

Who it is for

Makers, watch enthusiasts and builders who want to see how a mechanical watch actually goes together, those who want to machine their own, or fork the look by designing their own parts for it.
