So the commercial mentioned below was actually done in one take. They staked out a beach, built a faux boat deck and lowered a faux shower (complete with running water) then when all of that was moved, the actor bends down to supposedly grab the product, but is, actually, sitting himself down on the saddle which then moves over to the waiting horse.
CGI was incorporated in the diamonds and product as well as brushing out the arm that the saddle is attached to. Creators said the arm extend behind and to the front of the horse.
Regardless of all that, it's a fun spot and done in one take...granted it took them three days to shoot the one take, but still...quite impressive.
