Query: Good function, poor durability

I bought this watch for a bike race where I needed to keep track of two times (RAAM). After a week the watch worked fine, but the "crystal" was easily scratched and the stainless steel "case" dented easily. It appears that there is a very thin foil of stainless over a plastic case. I've had a Armitron that took 15 years of abuse and looks better than this after a week.If you're gentle on this watch, or don't care how it looks, it will serve you well.
