stitchdown construction

Guys i will be designing some tactical or work boots. Now before i start the work i needed to decide which sort of construction to choose. After lot of research and keeping different cost aspects in mind i think Stitch down construction will be best. like danner boots I now some of you guys will like to go with good year but that costs loot of $$$$.

I can get the stitch down construction done manually by hand but wanted to know which machine i need to consider if i decide to do this on large scale. I know its much be lockstitch but i am bit confused there are so many of them on the internet.

please see the video. machine is at 0:59

can anyone suggest its name??
