Hi,
I am very sorry for you that your watch is broken by shipping, I think that if someone sent a watch, I did it a few times myself, you know that it is fragile. I certenly want to ship the watch that it will arrive without any damages. So my advise is to ask the guy if he want to split the money you paid, it is his responsability that he ship the package secure and safe, and refund that to you, so that you can make the watch.
good luck
