the second link led to a blank page. I don't have any experience with stauer, but I have a couple different watches that I wear. both are very nice, and one is very similar to the first one you posted but it was my 18th birthday gift and outside the price range you gave and I rarely wear it because of that. I just picked up a nice Daniel steiger equinox at a charity auction. they make 2 different versions one that is very nice and expensive the other looks very similar but is about $175 and doesn't use as much gold but is very durable. You said you like lightweight so this might not be perfect for you because the band is black anodized stainless and there are many stainless parts. both are durable and can go to almost 400 ft underwater (a necessity in any daily use watch I buy because I do free diving and spearfishing). Its not the same style as the first one you posted (black and gold) but its a quality watch with a black face.
just what I can share from my experience.
