Cant ship the watches in a ziploc bag. So I did some searching for watch cases on Alibaba, ironically found the Helgray branded travel case.
Then I found these leather cases that I can have made (real leather). Branded with my brand logo or wordmark. If I order 500, price is $4.16 each! That's awesome, could double as sunglasses case as well. Would show that on the website/Kickstarter page.
Then, I was thinking I would order branded bubble mailers to slide those watch cases into. Would have Goodspeed Watches printed on the outside.
