My wife calls this “Blue Scottish Tartan.” I don't see any blue in it. I see black and green. But no watches. I googled “Black Watch Tartan” and saw a bunch of things that look just like this dog collar.
So if you are Scottish, or of Scottish descent, this collar will remind everyone outwardly of your heritage, and inwardly of haggis. If this style of tartan makes you so angry you just bit your whiskey bottle in half, try the Red Scottish Tartan. And trust us, as Americans, we have no idea why you're angry.3/4" Wide Collars:
