What are they even going to do with all that funding? It really doesn't seem like the product is very complicated or expensive. (no offense or anything)
It turns out that very simple things are very expensive to start with because of the low quantities. I thought an order for 30,000 was massive, but some companies we worked with flat out laughed in my face.
So even though he raised a million bones, he's "only" making < 13,000 watches. That'll still be pretty expensive for him.
Another point I forgot to mention above is assembly cost. I was surprised to learn that automating tasks isn't cost effective even when production is in the tens of thousands (depending on the task of course).
I assume he planned for a lower quantity initial run, so his margins are probably pretty high now. The "fixed" costs of initiating manufacturing are probably the biggest component.
